Genetics of Rice Under Normal and Water Stress Conditions

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. The crosses productive tillers per plant (Basmati-198 x CB-17), seeds per panicle (Basmati-2000 x CB-42, Basmati-198 x CB-14), 1000 seed weight (Basmati-2000 x CB-32, CB-42 x CB-32) and yield per plant (CB-32 x CB-14) sowed promising results for yield and yield related traits. Thus these hybrids could be used as such or further selection could made to develop high yielding rice genotypes suitable for cultivation under water stress condition. Over all this book will provide the information the breeders, geneticist, researchers and students related to genetic study of the rice crop.
