Title : Evaluation of per se performance of parents on grain yield and its component traits in rice (Oryza sativa L.)

Abstract :

Selection of parents based on per se performance and gca effects is of great relevance in breeding programme, in the event of the characters being under the complicated genetic control such as epistasis and linkage. Evaluation of parents based on per se performance and gca effects separately might lead to contradiction in selection of promising parents since per se performance of parents was not always associated with high gca effects [1]. Combination of both per se performance and gca effects would be able to identify parents with good reservoir of superior genes. So, the parents were evaluated for high per se performance as well as for high gca effects together. Considering the trait single plant yield the lines ACK 09009, IR 8 and CO 43 showed desirable gca effects combined with high per se performance. Along with high per se performance and good combining ability for yield the line IR 8 was also found to be good for grains per panicle, grain weight and plant height. The line ACK 09009 recorded high per se performance and gca effects for number of productive tillers per plant and panicle length along with yield. The line CO 43 which was found to possess desirable per se performance along with gca effects for yield exhibited the same trend for the traits grains per panicle. Among the testers ASD 16 recorded desirable per se performance along with significant gca effects for yield.
