Abstract

Thirty six single cross hybrids with six commercial checks were evaluated for yield performance along with earliness, plant height and ear height. The mean performance for days to tasseling and days to silking were significantly different among the hybrids. Considering the yield, Kaberi 50 and Pioneer 3396 were found as the best and the second best check, respectively. None of the hybrids produced higher yield compared to the best check Kaberi 50. On the other hand, L₁´T₁, L₃´T₁, L₅´T₃, L₆´T₃, L₁₀´T₁ and L₁´T₃ produced higher yield compared to 2nd best check Pioneer 3396 whereas L₅´T₃ and L₁₁´T₃ were earlier than the checks. The seven lines involving these crosses were selected for next generation evaluation. Better performing crosses showed higher K⁺/Na⁺ and lower contents of O₂^•-, H₂O₂ and melondialdehyde (MDA) than the susceptible crosses suggesting their better stress tolerance ability and thus better performance in yield.
