Correlation and path analysis studied in 18 Indian genotypes for 13 characters during kharif and rabi. The study indicated that direct selection based on the traits, number of productive tillers per plant and ear weight during kharif where as in rabi days to maturity and ear weight are effective as the association and direct effects were positive for these traits. The association of protein and calcium content and carotene with grain yield is negative. Simultaneous improvement of grain yield along these traits is not possible so we have to seek a compromise among the attributes to find out an acceptable level of the characters under improvement. The path analysis study indicated that direct selection based on the characters, number of productive tillers per plant and ear weight during kharif where as in rabi days to maturity and ear weight are effective as the association and direct effects were positive for these traits.
