ABSTRACT

To study the combining behavior of quantitative traits in rice, line*tester (4*3) progeny was generated involving 7 parents; 4 different lines,namely Super Basmati,Basmati 385, Basmati515 and KSK 133 and 3 well-adapted testers, namely, Basmati 198, PK 386 and KS 282. Super basmati, Basmati 515, Basmati198, Basmati 385, KSK 133 and PK 386 were found to be effective general combiners that provide excellent segregates for further selection. Basmati 385* KS 282, Super Basmati* KS 282, KSK 133* PK 386, Super Basmati* PK 386 and Basmati515* KS 282 hybrid combinations have higher specific combining ability (SCA) effects on grain yield and its components and can be used to exploit hybrid vigor to increase yields.
