Moench), also known as “lady’s finger”, belonging to the Malvaceae family, is an alloploid. Availability of haploids and doubled haploid lines are essential for the development of improved okra hybrid varieties. Anthers were excised from flower buds at different stages. The ability to produce haploid callus or somatic embryogenesis and thereby, regenerate into haploid plants was investigated. Several factors, such as flower bud initiation time, type of media and plant growth regulator combinations have been evaluated. The flower buds of different sizes were dissected to determine stages of development before subjecting to various pre-treatments and then the anthers. These were cultured on different PGR combinations (NAA, IAA, 2,4-D, KIN, BAP, IBA, ZTN, 2iP, GA3 and TDZ) and various concentrations. The cultures were incubated in both dark and light conditions. The suitable developmental stage of microspore for callus induction was obtained from 12 mm length of flower buds in okra for calli and root development. The effect of flower bud initiation time was an important factor in anther cultures. The media, MSNB, gave highest percentage (95 %) of callus induction. Incubation for 28 days in dark gave highest percentage (92.5 %) of callus induction. The ultimate aim of this study was to investigate the potential of okra anther culture. The study will ultimately help in double haploid development for faster crop improvement.","PeriodicalId":15010,"journal":{"name":"Journal of Applied Horticulture Lucknow","volume":"76 1","pages":"89-92"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83858026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data on variables affecting the price of greenhouse tomatoes were collected through a field study for a shortterm period from November 2014 to January 2017. The wholesale price of the crop was drawn from a market study for this period. The results show that the trend forecasted through General Regression Neural Network along with activating function of reciprocal is more efficient to estimate the training data. The Epsilon-SVR SVM acquisition pattern alongside the linear activating function was taken into consideration to estimate the testing data in an efficient way for two-month, three-month or biannual periods.","PeriodicalId":15010,"journal":{"name":"Journal of Applied Horticulture Lucknow","volume":"61 1","pages":"84-88"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83979739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pathogenicity and host range experiment revealed that Fusarium oxysporum isolate No.3 was the most virulent one to the susceptible cucumber cultivar “Beta alpha” and cucumber was the only infected host. The prevalence of the non-additive variance suggested heterosis breeding approach is effective way for improvement of these traits. Most of the traits exhibited significant hybrid vigor for some of crosses based on the better-parent. The analysis of variance showed that all the studied traits were highly significant indicating that both of the parents and hybrids had high variability. Significant general and specific combining ability variances were obtained in all studied traits implying that both additive and non-additive gene effects control genetic expression of these traits. The study showed that lines P2, P4 and P5 had significant positive GCA effects for total yield trait under fusarium wilt stress. Thus, these parents could be successfully used in future breeding programs. Among all the crosses, P1×P3, P1×P4, P1×P5, P2×P4 and P2×P5 exhibited significant SCA effects for both early and total yield characters under fusarium wilt stress. So, these hybrids can be used in future breeding program. The genotypes Kaha1×Dokky2 and Kaha1×Kaha2 followed by Kaha2×Dokky3 as well as Kaha1×Dokky3 were the most resistant genotypes decreasing disease severity correlated with increase in total phenol contents and activities of polyphenol oxidase, peroxidase and catalase as compared to susceptible genotypes, i.e., Dokky3, Kaha1×Dokky1 and Dokky1. The scavenging activity was higher in susceptible genotypes as compared with resistant genotypes. Furthermore, there was a high correlation between the total phenol content and the scavenging activity. Results also revealed a noticeable significant correlation between disease severity, total yield and early yield traits. Cluster analysis classified the fifteen genotypes into five clusters with different number of genotypes. Further improvement of fruit yield could be possible through the hybridization and selection in transgressive segregation.","PeriodicalId":15010,"journal":{"name":"Journal of Applied Horticulture Lucknow","volume":"66 1","pages":"255-264"},"PeriodicalIF":0.0,"publicationDate":"2020-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78221832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The herbicides metribuzin, topramezone, mesotrione, and ethofumesate were evaluated in tank mixtures for bermudagrass and mature goosegrass control and seashore paspalum injury. Goosegrass was controlled with tank mixes that included topramezone (0.01 kg ha-1) + metribuzin (0.10 kg ha-1) with an acceptable level of seashore paspalum discoloration. Incorporating a post-spray dry down allowed for complete control of goosegrass with one spray application.

Gynoecious, an important agricultural trait which highly correlates with yield, was proved to be controlled by F locus. Conventional plant breeding approach has some limitations in term of potential inaccuracies and time-consuming. Molecular marker-assisted breeding is, therefore, an effective alternative solution. F locus– linked molecular marker has been reported previously. The main aim of this project was to evaluate the potential applicability of this F locus–specific marker for marker–assisted selection in Vietnam cucumber breeding program. Three different cucumber populations e.g., pure lines, F2 and F3 population were utilized with 13, 131 and 84 plants, respectively for each population. Plant sexual phenotypes were determined. Sequencing reactions were performed for BCAT 3’UTR of 3 gynoecious and 2 monoecious pure lines. Plant genotypes were determined by standard PCR with a primer pair amplifying a 56 bp-deletion region in BCAT 3’UTR. A 56 bp-deletion was found in BCAT 3’UTR of gynoecious pure lines as compared with monoecious lines. The marker based on this 56 bp-deletion region in BCAT 3’UTR could help to separate cucumber plants having homozygous and heterozygous sex phenotypes. The marker genotype absolutely corresponded with monoecious trait. Especially, the marker could precisely explain for 80 % gynoecious trait. The marker highly explained for Vietnam cucumber sex traits and could be applied for marker-assisted selection in cucumber breeding program in Vietnam in future.","PeriodicalId":15010,"journal":{"name":"Journal of Applied Horticulture Lucknow","volume":"8 1","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89739954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ariffin","doi":"10.37855/jah.2020.v22i02.22","DOIUrl":"https://doi.org/10.37855/jah.2020.v22i02.22","url":null,"abstract":"The study was conducted on a polyembryonic mango, Harumanis which contains more than one embryos including one zygotic and single or more number of nucellar ones. In this paper, we used microsatellite markers to identify whether the seedlings of Harumanis were zygotic or nucellar. A total of 95 progenies of Harumanis were evaluated using 13 polymorphic microsatellite markers. The genetic profiling revealed that a total of 14 Harumanis progenies were zygotic or open pollinated seedling as their genetic profile was different with Harumanis at least at one loci. Nevertheless, 76 Harumanis progenies were true to type or nucellar seedlings as their genetic profile was similar to Harumanis. The remaining five progenies could not be identified with the call rates of the genotypic data. Identifying true to type or nucellar seedling is useful for nursery growers to determine the true to type Harumanis progenies from the seed. Meanwhile, the open pollinated seedling or zygotic seedlings are preferred by breeders as they are considered as a new variety which increases the mango genetic variability. Key word: Mango, Harumanis nucellar, zygotic, microsatellite Introduction Harumanis is considered the “King of Mangoes,” gaining popularity in Malaysia because of its deliciousness, and sweet and aromatic fragrance. Harumanis is polyemroyonic thus its seed contains more than one embryo, which may be both zygotic and nucellar or all nucellar embryos (Shukla et al., 2004; Degani et al., 1993). In mangoes, this trait is genetically controlled by a single dominant gene while the cultivar and environmental conditions influence the number of seedlings produced from a seed (Aron et al. 1998; AndradeRodríguez et al., 2005). The nucellar tissue that covers the embryo sac forms the nucellar embryos and produces genetically identical seedlings to its parent plant (Aron et al., 1998). These seedlings from nucellar embryos are true to type as their mother and are preferred by nursery growers to produce rootstocks because using them results in a more even orchard (Rao et al., 2008). On the other hand, fertilization either by self or cross-pollination forms zygotic embryo. This type of embryo will produce new open-pollinated progenies imperative for the development of new mango varieties. Unfortunately, based on morphological criteria, it is difficult or not possible to identify whether the seedlings are derived from nucellar or zygotic embryos (Desai, 2004), making molecular markers imperative for identification purpose. In general, the most vigorous seedling from each seed is used to produce rootstocks. Unfortunately, uneven orchards may occur because the nucellar seedling is not always the most vigorous (Rocha et al., 2014) which lead to impractical identification of nucellar seedlings using morphological characteristics. To differentiate zygotic and nucellar embryos, researchers used genetic markers, including isoenzymes (Degani et al., 1993), RAPD (Ochoa et al., 2012), and","PeriodicalId":15010,"journal":{"name":"Journal of Applied Horticulture Lucknow","volume":"31 1","pages":"122-126"},"PeriodicalIF":0.0,"publicationDate":"2020-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81044258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional exhaustive organic inputs, self renewable organic inputs like plant growth-promoting rhizobacteria (PGPR) were tested against the soft rot incidence in ginger for two consecutive years. Two local varieties, namely, Bhaise and Majouley were used with conventional organic inputs and PGPR, alone and in combinations. The disease causing organism was challenge inoculated. The disease symptoms were assessed by visual scoring. In addition, growth and yield parameters were recorded. The results revealed that PGPR along with the other organic inputs have significant effect on disease suppression in addition to promoting the growth and yield parameters like plant height, number of leaves, number of tillers, leaf area and yield per plant.
