Correlation and path analyses among floral characters of drought resistant cultures of rice

摘要

Twenty five drought resistant cultures were raised at Agricultural College and Research Institute, Killikulam in randomized block design and replicated thrice and the relationship between seven characters namely ovary length, ovary width, style length, stigma length, anther length, anther width, filament length with pollen fertility was compared through correlation and path analyses. Correlation studies revealed that ovary length has positive and significant association with pollen fertility. Ovary length, stigma length, anther width and filament length has positive direct effect on pollen fertility. However, only ovary length has positive significant association with pollen fertility. Hence selection of spikeiets based on ovary length will increase the pollen fertility
