The present study aimed to estimate the nature and magnitude of variability present in castor genotypes with respect to yield and its contributing traits. A study with 15 genotypes on variability, correlation, path and genetic divergence was carried out for thirteen characters. The variability in oil content ranged from 46.75% to 51.71%. The genotypic and phenotypic coefficients of variation were high for number of capsules on main raceme. Positive association of number of nodes up to primary raceme and total length of primary raceme was observed with seed yield per plant hence, these traits may be directly attributed for the improvement of seed yield. The path coefficient analysis demonstrated that utmost positive direct effect on seed yield per plant was exerted by total length of primary raceme (0.62). Mahalanobis D<sup>2</sup> statistic grouped the 15 genotypes into seven clusters. Number of capsules on main raceme contributed much to the total genetic divergence. Selection of genotypes from diverse clusters like cluster II and V, and cluster II and VII for hybridization programme would help in achieving novel recombinants. In conclusion, for the improvement of seed yield the main emphasis should be given on total length of primary raceme and number of nodes up to primary raceme. However, shelling out turn should also be taken into account to improve oil percentage.</p></div>","PeriodicalId":100092,"journal":{"name":"Annals of Agrarian Science","volume":"16 2","pages":"Pages 143-148"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasci.2018.02.004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91756844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first three principal components (PCs) explained 69.69% variation. Four groups of characters were distinguished in regard to first (PC1) and second (PC2) principal components. Factor analysis indicated that three main factors accounted 69.69% of the total variability. Three first factors accounted for 33.69%, 20.82% and 15.19% of total variability, respectively and the terms proposed for factors were ‘phenological traits’, ‘morphological traits’ and ‘yield components’. Communalities indicated that studied traits were reliable and ranged from 0.537 (canopy height) to 0.881 (seed yield). Two-dimensional ordination biplot indicated positive correlation between seed yield, pods per plant, canopy width, harvest index and biological yield. Cluster analysis grouped 25 genotypes into two main groups and four clusters. At a distance of 5, the 11 traits examined formed into two clusters. These findings can be used in breeding strategies for future hybridization programs for yield improvement and are appropriate for classification of diversity among chickpea germplasm.</p></div>","PeriodicalId":100092,"journal":{"name":"Annals of Agrarian Science","volume":"16 2","pages":"Pages 136-142"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aasci.2018.02.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91720701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Development of competent and time saving tools for assessing the varying expression of agronomic traits of a crop and understanding its genetic background is a prerequisite. Recently, the commercially important beverage crop, tea (<em>Camellia sinensis</em> (L.) O. Kuntze), is of prime importance for its worthwhile health-benefit attributes. Although due to some inherited bottleneckness, several advanced genomics and phenomics technologies have already been utilized in tea for crop improvement program. Attempts have been made for its yield and quality trait associated marker development and next generation phenotyping considered to be the unique point of scientific interest.
