Seed Production Environment and Potential Seed Longevity of Rain-fed Sesame (Sesamum indicum L.) Genotypes

Abstract: Variability and adaptability of potential seed longevity were investigated in 14 sesame genotypes grown in three plant population environments in South Western Nigeria in each of the two cropping seasons. Seeds obtained from these genotypes were subjected to accelerated aging test using methanol-aging techniques. Data obtained were subjected to analysis of variation and differences, means separation at 5% probability level and stability test. The test genotypes exhibited significant differences in seed longevity in five out of the six environments. Genotype 73A-11 had distinct seed longevity potential in all the environments except in 266,667 plants ha^-1. The stability analysis result indicated that regression coefficients ranged from 0.05-2.06 and were statistically close to unit. Four genotypes, 73A-11, 93A-97, E8 and CK2 were desirable with high seed longevity potential in all the environments. Genotype 73A-11, 93A-97, E8 and CK2 were identified as desirable genotypes with potential for high longevity in any of the three plant population densities. The result further identified 73A-11, 93A-97, E8, CK2 and Pbtil as being most appropriate in 133,333 plants ha^-1 and all the genotypes except 93A-97, Type A, 530-6-1 and 69B-882 in 166,667 plants ha^-1while all the genotypes except Type A, 530-6-1 would be appropriate in 266,667 plants ha^-1. The identified genotypes were superior in seed longevity potential and hence could be considered in commercial seed production and future seed improvement programme.
