In the present study, 24 different Bhut Jolokia chilli landraces and seven Capsicum annuum cultivars have been collected from the northeastern region of India and subsequently screened under in vitro and in vivo conditions against Colletotrichum capsici and C. gloeosporiodes infections. During field evaluation, eight chilli genotypes (CC0164, CC0165, CC0191, CC0192, CC0202, CC0206, CC0209 and CC0218) were highly resistant and 12 genotypes (CC0154, CC0179, CC0181, CC0183, CC0186, CC0189, CC0193, CC0198, CC0205, CC0210, CC0213 and CC0217) were found in resistant category against C. capsici infection. During in-vitro germplasm evaluation, 11 and 12 landraces were found to be highly resistant to C. capsici and C. gloeosporioides infections, respectively. According to the findings, the majority of Bhut Jolokia chilli landraces are resistant to anthracnose. Given the difficulties farmers experience as a result of excessive use of fungicides and pesticides, germplasm screening for host resistance has already begun. The resistant lines identified in the current study offers better choices to tackle anthracnose and could be used effectively in breeding programs to develop anthracnose resistant varieties.","PeriodicalId":20252,"journal":{"name":"Plant Genetic Resources: Characterization and Utilization","volume":"229 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73953169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study was conducted on eight qualitative and 14 quantitative traits related to growth and floral attributes for characterization and grouping of 54 chrysanthemum genotypes. Wide variability was observed among most of the traits and principal component analysis revealed that the first two principal components explained most of the existing variation (>98%) in germplasm. Genotypic coefficient of variation exhibited a wide range from 9.41% (ratio of leaf length/width) to 105.99% (corolla tube length of ray florets), while phenotypic coefficient of variation varied from 10.49% (ratio of leaf length/width) to 106.38% (corolla tube length of ray florets). Broad sense heritability estimates were higher (>96%) for most of the characters, except for traits such as ratio of leaf length/width and peduncle thickness. Forty-four pair-wise inter-trait combinations showed positive genotypic and phenotypic correlations for 91 possible combinations. D2 analysis revealed that genotypes of clusters I and IV to be highly distinct, and hybridization between them might have better chance to obtain desirable types. D2 analysis confirmed that the cultivars in cluster IV namely, Red D Spoon, Tokyo Soldier, Yellow Reflex and hierarchical clustering showed that the cultivar Tokyo Soldier to be highly diverse. It is recommended to use the above genotypes in crossing programme for obtaining better progenies.","PeriodicalId":20252,"journal":{"name":"Plant Genetic Resources: Characterization and Utilization","volume":"32 1","pages":""},"PeriodicalIF":1.1,"publicationDate":"2022-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78412932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Crosses of twenty-six lines (female) with each of two I. cylindrica and twenty-one maize genotypes (testers) were evaluated for four haploid induction parameters viz., pseudoseed formation frequency (PFF), embryo formation frequency (EFF), haploid regeneration frequency (HRF) and haploid formation frequency (HFF). I. cylindrica outperformed maize in haploid induction rate with a frequency of embryos formed with I. cylindrica (18.39%) were significantly higher as compared to maize (4.08%).

Tomato leaf curl virus (ToLCV) is a begomovirus transmitted through the whitefly (Bemisia tabaci) and is responsible for severe losses in tomato production. In this context, the current investigation was carried out to determine heterotic combiners with high yield, resistance to ToLCV and mode of gene action for economically important traits. For this, 11 prescreened inbred lines were crossed in a half diallel fashion to generate 55 F1 hybrids. The 55 crosses with 11 parents and commercial checks were evaluated for different horticultural traits and resistance to ToLCV. The molecular validation with SCAR markers TG0302 and SCAR1 confirmed the presence of ToLCV-resistant genes in parents and their crosses. The hybrid IIHR-2902 × IIHR-2852 showed the presence of both Ty-2 and Ty-3 alleles in the homozygous state. The estimation of σSCA2 and σGCA2 was significant. It also indicated that the genetic control of target traits was under additive and non-additive gene effects. The values of σA/D2 along with σGCA2/σSCA2 found to be less than unity indicates the preponderance of non-additive gene action in the expression of the studied traits except for percent disease incidence. The parental line IIHR-2919 was the best combiner for fruit and yield traits. The cross combinations IIHR-2913 × IIHR-2898 exhibited significantly higher economic heterosis for yield along with the presence of Ty-2 and Ty-3 genes.
