Abstract

Extent of genetic diversity in a collection of 41 sesame
genotypes comprising advanced breeding lines and
varieties was assessed based on phenotypic (19
morphological and quantitative traits) and genotypic (68
SSR loci) data. Wide variation was observed for quantitative
traits, namely, plant height (86-137 cm). No. of capsules/
plant (42-116), days to maturity (81-103) and seed yield/
plant (10-23g)., SSR markers showed 29% polymorphism
with an average of 2.8 alleles/locus and 0.409 PIC value
indicating a trend of moderate level of diversity at molecular
level in the collection. The results reinforce the need for
using both phenotypic and molecular data for genetic
diversity assessments and selecting diverse lines for
breeding programmes.
