Genetic Variability for Seed Ageing and Longevity Among the Advanced Sweet Sorghum Genotypes and Cultivars

Twelve sweet sorghum genotypes were evaluated for seed germination and vigour traits under accelerated ageing and natural storage conditions to examine the genetic variation, heritability and correlation. Loss in seed germination, field emergence and seedling vigour were more due to accelerated agei...

Description
Summary:Twelve sweet sorghum genotypes were evaluated for seed germination and vigour traits under accelerated ageing and natural storage conditions to examine the genetic variation, heritability and correlation. Loss in seed germination, field emergence and seedling vigour were more due to accelerated ageing than natural storage. Seedling vigour showed moderate values of phenotypic and genotypic coefficients of variation, high values of heritability (h2-bs) and moderate to high values of genetic advance over mean of fresh, aged and stored seeds. Genotypic and phenotypic correlations explained the extent of association among the seed physiological traits.
