LINE X TESTER ANALYSIS IN BASMATI RICE

 MUHAMMAD RASHID^*, AKBAR ALI CHEEMA AND MUHAMMAD ASHRAF

Abstract: 2 line x 3 tester mating design along with 5 rice genotypes and 6 F₁s were used of line, tester was higher than that of interaction of line x tester for all the characters. The predictability ratio indicated the predominance of non-additive gene action in the inheritance of all these characters. The highest significant heterosis (61.9) was observed in the cross Super Basmati/DM-107-4 for yield/plant. The female Super Basmati, male DM-25 and DM-107-4 were observed to be good general combiners for most of the characters studied. The crosses between Basmati-370/DM-25 and Super Basmati/DM-107-4 were observed good specific combiners for yield/plant. However, the cross combination Basmati-370/EL.-30-2-1 was identified as the promising specific combiner for further improvement in rice.
