They were characterized based on morphological, physiological, biochemical and molecular characteristics. The results on plant growth promoting traits showed all isolates positive to IAA production, four positive to ammonia production and five positive for in vitro siderophore production. Three isolates exhibited antagonistic activity and none of them showed volatile cyanogen production. The 16S rRNA gene sequence analysis revealed all the isolates to show similarity to Rhizobium sp. While rhizobia generally have a pH range of 6.5–7.5 for optimum growth, the isolates RH-1. RH-2, RH-4 and RH-8 grew in a liquid yeast extract-mannitol agar medium at pH-4, suggesting acid tolerance in the strain of Rhizobium. The isolates were authenticated for their nodulation and growth promotion of cowpea in a paper cup experiment and four isolates (RH-2, RH-3, RH-4 and RH-5) were evaluated for their growth promotion in cowpea under field condition. It was observed that inoculation of Rhizobium increased nodulation, growth parameters and yield of cowpea compared to uninoculated control. This study showed that these rhizobial isolates with plant growth promoting traits can be used to promote the growth and yield of cow peain acidic soils of Kerala.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"74 1 1","pages":"126-133"},"PeriodicalIF":0.8,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89191043","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}

SBC-47) production. The treatment consisted of four levels of P (20, 40, 60 and 80 mg P kg-1 soil) and four levels of S (10, 20, 30 and 40 mg S kg-1 soil). The experiment was laid out in factorial completely randomized design with three replications during kharif season of 2016. The experimental soil was deficient in available phosphorus (13.85 kg ha-1) and available sulphur (15.91 kg ha-1). The results revealed that combined application of P and S had significant effects on seed and stover yield of black gram. The optimum seed and stover yield were recorded with combined application of 60 mg kg-1 soil and 30 mg kg-1 soil, respectively which was statistically at par with combined application of 80 mg P kg-1 soil and 40 mg S kg-1 soil. The assessment of temporal availability of phosphorus and sulphur at 20, 40 DAS and after harvesting of black gram in acid Inceptisol of Meghalaya indicated that available phosphorus in soil increased with each successive increasing level of P application, however it showed decreasing trend with time intervals of 40 DAS and after harvesting of black gram at each successive dose of 40, 60 and 80 mg P kg-1 soil over 20 mg P kg-1 soil in the presence of S fertilization. Similarly, available sulphur in soil also increased with each successive increasing level of S application, whereas it also showed decreasing trend with time intervals of 40 DAS and after harvesting of black gram at each successive dose of 20, 30 and 40 mg S kg-1 soil over control as 10 mg S kg-1 soil in the presence of P fertilization.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"11 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2019-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85852454","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}

In the present study, total 26 geographically diverse French bean genotypes collected from different agro-climatic zones of Himachal Pradesh and two check varieties viz., Baspa and Jawala were grown under randomized complete block design with three replications for deciphering the extent of genetic diversity. The extent of variability was assessed using DUS morphological traits and PCR based approach. Analysis of variance for quantitative traits showed significant differences among all the genotypes for all the characters studied. The genotypes RL-19 and RL-20 gave higher seed yield and performed better for many of the horticultural traits over all the checks. Further, 15 RAPD primers were used for scoring polymorphism at the DNA level. The French bean landraces produced 79 PCR fragments, of which 59 were polymorphic with an average of 3.93 polymorphic fragments per primer. The overall percentage of polymorphism was recorded 74.62 per cent. The average Jaccard similarity index among genotypes ranged from 0.48 to 0.98, thereby showing sufficient genetic variability. Geographical affiliations and morphological associations were observed while studying the genotypic patterns within each group i.e. A, B, C and D. Such variability is desirable in breeding programs. Which also reveal the inherent capacity of the community as a selector, conservator and improver of the potential genetic resource for sustainable future.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"55 1","pages":"470-479"},"PeriodicalIF":0.8,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86316402","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 undertaken to evaluate agronomic performance of cowpea germplasm and select the candidate accessions for breeding population and cultivation by small-scale farmers in South Africa. A randomized complete block design with three replications was used for the experiment. Data were collected on the agronomic traits including days to 50% maturity, days to 95% maturity, hundred seed weight, leaf area index, number of branches, number of internodes, number of seeds per plant, plant height, number of pods per plant, pod length, dry biomass weight per plant, grain yield per plant and grain yield per hectare. Highly significant differences were observed among the accessions for all traits. The grain yield per hectare was correlated positively and significantly with number of pods per plant and grain yield per plant showing a scope for simultaneous improvement of yield and yield related traits. Principal Component biplot revealed that accessions Acc2024, Acc5352, Acc2355, Acc4565, Glenda and L-cwp3 were the most genetically distinct accessions and can serve as potential candidate parental lines for hybridization to achieving transgressive segregation population in breeding programmes.","PeriodicalId":18181,"journal":{"name":"Legume Research","volume":"41 1","pages":"757-762"},"PeriodicalIF":0.8,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78478623","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}

However, water-soluble protein banding pattern revealed the presence of 16 bands including 8-12 variate of RM-value (0.16 to 0.95) with four common bands of RM-value 0.43, 048, 0.23 and 0.65, respectively. UPGMA cluster analysis was used to group the 13 genotypes into six distinct clusters. The banding pattern of tris-soluble protein was found to be more distinct than water-soluble protein.
