Abstract:
Fifty-five landraces of kharif sorghum were evaluated and correlation coefficient were estimated for the grain yield and the yield contributing traits including the grain mold rating. Correlation studies revealed that the plant height exhibited positive significant association with fodder yield per plant indicating the role of plant height in increasing the fodder yield. The seed hardness showed positive significant genotypic correlation with germination percentage of seed indicating the importance of seed hardness in improving the germination percentage of seed. Threshed grain mold rating recorded negative significant correlation with germination percentage indicating that higher grain mold infestation is responsible for reducing the germination percentage of seed. Specific gravity of seed exhibited positive and highly significant association with 1000 seed weight thereby indicating the role of specific gravity in development of bold seeded genotypes in sorghum. Germination percentage of seed exhibited highly significant and positive association with vigour index of seed.
