Not AvailableIn order to know the variation in seed quality among the varieties and hybrids (public, private sector) of sorghum collected from different market outlets. A total of 52 lots (38 cultivars) were evaluated for seed germination and seedling vigour. The values ranged significantly from 1.67 g (KDSH 302) to 4.60 g (MRS a6 9) for hundred seed weight;55% (CSH 16) to 97% (CSH 14) for seed germination; 9.2 cm (CSH 1.6) to 16.93cm (JKSH 434) for root length; 11.15 cm (MSH 51) to 20.95cm (Sudhama 333) for shoot length; 10.21 mg (KDSH 302) to 28.22mg (MRS 4649) for seedling dry weight and 728 (KDSH 302) to 2196 (JKSH 22) for seedling vigour index traits. Whereas, CSH 16, JKSH 474, NSH 36, KDSH 302, CSH 9, NSH 18, MDSH 262 ,VIH 540, MSH 51 and'Local farm market (Udaipur)' showed low values of germination ranging from 55 to75% (lesser than minimum seed certification standard) which is alarming and needs attention for searching the causes and solutions. The differences for these seed quality traits within the cultivar were also observed due to different market sources as found in 11 cultivars. Farmers become aware of vigour differences when the germination test fails as measure of quality for expensive seeds. The study highlights the importance of seed vigour and suggests the supply of standard quality seed by seed industry which is essential to realize the performance of cultivars on farmer field.

Not AvailableTwelve 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.Not Availabl
