ABSTRACT
A line x tester set was obtained by crossing 10 inbred lines with four testers in maize. Forty F1’s along with14 parents and two standard checks were evaluated for eleven characters during rabi 2004-05. Out of 40 crosses, 23 crosses over better parent and 11 crosses over standard check were significantly out yielded for grain yield. The crosses DMR 274 x HOL 34, DMR 201 x EI 34 and DMR 156 x EI 34 showed high heterosis over better parent and standard check(DHM 103) for grain yield per plant as well as for 100 seed weight, ear length, chlorophyll content at 50 % flowering and plant height. Thus, these crosses possess high heterosis, in future could be exploited commercially for higher yield in maize.
