EFFECTS OF BIPARENTAL MATING IN FORAGE OATS

Abstract

Effects of biparental matings (BIP) were studied in two oat (Avena sativa L.) crosses alongwith their parents. TI,e mean values of BIPs were better than the mean values of parents (selfed) for all the charactrs studied in both the crosses. In general, the lower limit of range shortened and the upper limit increased in desired direction. The analysis of variance of biparental progenies indicated significant variation among BIPs (for both the crosses) for all the characters studied except leaf width and leaf:stem ratio in the cross, UPO 210 x UPO 136. A comparison of genotypic and phenotypic correlations among the characters between the biparental progenies and selfs indicated several new correlations in the BIPsas compared to the selfsin both the crosses suggesting breakage of the linkages.
