Genetic Variability in Sesame (Sesamum indicum L.) Genotypes for Shattering and Shattering-Related Traits

Shattering has a substantial yield reduction in sesame. Sixty-four sesame genotypes were evaluated using 8 x 8 lattice design with two replications at the main research station of Pawe Agricultural Research Center to assess the genetic variability among sesame genotypes for shattering and shattering-related traits. Data were collected on days to first capsule opening, days to 90% maturity, number of opened-capsules plant-1, number of total capsules plant-1, length of cracking on opened-capsule, number of seeds dropped opened-capsule-1, number of seeds dropped opened-capsule-1 while the capsule is inverted, and the number of seeds retained opened-capsule-1. In the present study, the mean seed retention and rate of shattering capsule-1 ranged from 22.56% to 73.71% and from 26.20% to 77.78%, respectively. Analysis of variance revealed significance difference (P<0.05) among sesame genotypes for number of days from first capsule-opening up to days to 90% maturity, while the evaluated genotypes showed non-significant difference (P>0.05) for rate of shattering and other shattering-related traits which indicated low scope of improvement for shattering resistance through the evaluation and selection of landraces. Furthermore, low estimates of heritability and genetic advance as percentage of the mean for shattering and its related traits indicated that an environment had a significant influence on these traits, which suggests breeders to evaluate sesame genotypes for shattering resistance based on molecular data rather than phenotypic data for reliable results and valid recommendations.
