EFFECTS OF BIPARENTAL MATING IN FORAGE OATS

Published on

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.
