These studies presence of sufficient exploitable genetic variability for various yield related traits among the rice genotypes. A good number of rice genotypes were screened and identified on the basis of various morphological, physiological and molecular studies, that would be used in the development of F1 hybrid seed. The genotypes CB-17, CB-32 and Basmati-198 were good general combiners for productive tillers per plant, primary branches per panicle and yield per plant, especially under water stress condition and also gave specific cross combinations for good yield and yield related traits....
