dc.description.abstractBreeding for yield improvement in self-pollinated crops requires identification superior of crosses in early segregating generations, thus enabling the breeder to grow large populations in subsequent generations for recovery of desired genotype ( s). A study was therefore, undertaken in rice to verify breeding behaviour of F3 families in relation to breeding potential of crosses identified in F2 generation. Among ten crosses involving 13 parents evaluated in F2, five crosses namely Daya/IR36, Shrabani/IR36, IR72/ORP665-14, IR36/KM30 Shrabani/IR64 and Ajaya/Jajati, Shrabani/IR36 were found potential. The evaluation of F3 families of the ten crosses revealed that Daya/IR36, namely crosses four crosses of out 10 and Birupa/IR64 were found potential. Further the classification of F2 plants into low, Yielding categories revealed their medium and high importance in F3 by showing high magnitude of mean performance and variation in progenies of high yielding category than in the low. On the basis of the present study it may be stated that predictions for high grain yield in rice from the mean performance of parents and early generation bulk hybrids would seem to be useful and reliable in obtaining potentially superior segregants for release as cultivar(s).en_US
