Evaluation of early and high yielding mutants of sesame (Sesamum indicum L.) for different genetic parameters
Publication date:
Twenty-eight genotypes of sesame in the M4 generation, obtained through the use of gamma radiation, were evaluated at Nuclear Institute for Agriculture and Biology, Faisalabad, Pakistan during 2005-06. Data on seed yield and its component, i.e. days to flower, days to mature, plant height, number of branches per plant, capsules per plant, capsule length and seeds per capsule, were recorded and analysed for correlation, path and genetic parameters. Capsules per plant showed significant genotypic and phenotypic correlation while highly significant and positive genotypic correlation with seeds yield. Positive direct effects were observed for capsules per plant and seeds per capsule. More than 50 percent heritability was noted in all attributes except seed yield per plant. However, maximum genetic advance was estimated in seed yield (45.25) followed by number of branches (41.32) and capsules per plant (31.13). It may be concluded that for direct selection maximum emphasis should be given primarily to capsules per plant followed by seeds per capsule and capsule length. Based on these attributes, high yielding and disease resistant mutants have been obtained.
