Genetic study and path analysis in pearl millet.

摘要

Correlation and path co-efficient analysis were carried out in twenty-one parents and hundred and ten F1 genotypes in pearl millet for ten characters during kharif 1999 in Coimbatore, Tamil Nadu, India. The grain yield had high significant positive correlation with plant height, earhead length, earhead girth and productive tillers. The leaf width showed very high positive association with earhead length, earhead girth, and 100-grain weight with grain yield. The path coefficient study revealed that the earhead length had high positive direct effect on grain yield followed by plant height, earhead girth and productive tillers. The 100-grain weight showed high indirect effect through leaf number, plant height and leaf length and the leaf number exhibited high indirect effect on leaf length and earhead length on grain yield.
