| Description |
An investigation was undertaken on sesame at K Block, Department of Genetics and Plant Breeding, University of Agricultural Sciences, GKVK, Bangalore during 2005-2007 to identify the ideal crop growth stage to study the root morphological traits using ten sesame lines; to estimate the genetic variability parameters and stability performance of 35 select sesame genotypes for seed yield, its component traits and root traits under three moisture regimes; to know the genetics of root morphological traits using two crosses and seed yield using three sesame crosses. The results revealed that, 60 DAS was the ideal growth stage in sesame for root sampling. A close correspondence between PCV and GCV for root traits indicted lower interference of environment. The genotypes RT-343, YLM-66, CSI-94- 20, RT-46, Rangapura, TKG-306, PKDS-41 and Shivanakere for root traits and CSI-94-20, PKDS-41, LTK-4, JCS-399, RT-125, Chinnappana Hatti and RT-54 for seed yield were desirable under all the three moisture regimes. Dominance and dominance × dominance types of gene effects were predominant with duplicate epistasis in the inheritance of traits. The F2 of the crosses TKG-314 × CST-2001-05 and MT-19-03 × AT-87 recorded higher variance than their parents which indicated the scope for recovery of large number of trangressive segregants in F2. The entries RT-342 and Co-1 for root traits and Chinnappana Hatti, CSI-94-20, JSC-399, MT-111, RT-125, Navile and RT-54 for seed yield were found stable under moisture stress-free environment. |
