STUDIES ON SEED VIGOUR IN SORGHUM

Abstract

                                Studies made on the nature of association of different vigour tests with field emergence in sorghum (CSH 5) seeds revealed that standard germination, vigour index, germination after soaking them in sodium hydroide and ammonium chloride solutions and rate of germination correlated positively and highly significantly with field emergence. Rate of germination exhibited the maximum correlation coefficient of 0.764 with field emergence. Among the germplasm varieties. Is 3096, Is 1025, Is 6391, Is 2971, Is 2625 and Is 3541 recorded more than 95 per cent germination after nine months of storage. Varieties varied in their sensitivity to NH,CI soak test.
