Genetic analysis of diverse castor (Ricinus communis L.) genotypes based on seed related morphometric traits

Diverse source of early genotypes is obligatory for breeding high yielding castor (Ricinus communis L.) cultivars. One hundred and twenty-five medium duration including three checks were evaluated the presence genetic diversity variability. Genetic distance, variance components correlation coefficients estimated seven seed related quantitative traits. Significant genotypic differences observed among collections these High heritability advance noticed length, breadth, Length/Breadth ratio, shelling percentage, 100 weight yield per plant, thus mode gene action reported was additive. analysis based on dendrogram, phenogram circular form grouped entries into groups it computed inter intra cluster distance. Principal Component Analysis (PCA) revealed that first cumulatively accounted 72.57  cent total variation. Seed plant showed significant association with percentage weight. Also, direct effects positive through ratio The promising identified (ICIRG 2272103 RG 1673) information generated would be useful early/medium cultivarsas well to understand physiological mechanism earliness in castor.
