Wild species of Rice offer an important source of variability for improvement of cultivated Rice.Wide hybridization is the only way to transfer useful genes from wild species into cultivated Rice.In order to utilize the resistant potential of Oryza rufipogon to various biotic and abiotic stresses, this species was crossed with cultivated varieties of Oryza sativa. The crossability between O. sativa and O. rufipogon varied from 17.5-33 (%). The highest crossability was observed in IR-6/O. rufipogon (33%) and least in KS-282/O. rufipogon (17.5%). Based on crossability, IR-6 showed a close...

Rice is ranked as the worlds number one human food crop and accounts for more than half of the worlds daily calorie intake. It is an economically important food crop that is domesticated after wheat and helps in poverty alleviation. In the present study, 20 advanced lines were evaluated for yield and yield attributing traits and resistance to bacterial blight. For quantitative trait analysis out of 53 traits, 13 agronomic traits, 29 morphological traits and 11 grain quality traits were studied.
