Abstract

Forty Five single crosses without reciprocals in 10 x 10 full diallel were attempted during rabi 2010 and the F1 were evaluated in different seasons under coastal saline situations. The mean squares due to gca and sca were found significant for all traits across the seasons. In general the parents MTU 1061 and MTU 1001 were noticed to be good general combiners in all the seasons for grain yield and majority of yield component characters studied in the present investigation. Among the hybrids, NLR 33359 x MTU 1001, NLR 40024 x MTU 1061 and NLR 40024 x MTU 1001 were noticed to be good specific combiners across all the seasons studied with regards to yield components and grain yield indicating their potentials as promising hybrids for saline conditions. Hence, these crosses can be subjected to pedigree breeding to evolve high yielding genotypes suitable for coastal saline soils.
