摘要：

The effects of different moisture stress conditions on performance of 85 quality protein maize (QPM) genotypes were measured. Significant variations among the genotypes were observed for grain yield/plant and quality traits (protein, lysine & tryptophan). The study showed that hybrids NP-06-07R-74-10-1-1 x HO6R-6136-64-1-4-1 and NP-06-07R -73-6-1#1 x HO6R-6136-64-1-4-1 gave superior performance in all the environments with respect to yield, economic heterosis and percentage loss in stress. The inbreds viz., (CML 161 X CLQ-6203) B-4-1-1-B-2-B-1 and HO6R-6136-64-1-4-1 were best for grain yield, while, the inbreds NP-06-07R -76-11-2-1, NP-06-07R -73-6-1#1 and (CML 161 X CLQ-6203)B-4-1-1-B-2-B-1 were best for both lysine and tryptophan. The correlation between different moisture stress conditions and quality traits was positive. A single cross hybrid NP-06-07R -73-6-1#1 x HO6R-6136-64-1-4-1 was identified as superior for grain yield/plant, Lysine and tryptophan contents in all the environments as compared to best check HQPM-5.
