ABSTRACT
Seventeen maize genotypes were evaluated for chemical composition at baby corn stage and grain maturity stage (hard dough stage). For baby corn purpose, the parental line, BQPM-4 was found to be good in moisture, reducing sugar and crude fibre content while BQPM-2 was found to be good in dry ash content. Calcium, iron and phosphorus contents were relatively more in CML 161, CM 150 and HKI 193-1. However, for grain purpose, BQPM-2 was found to be good in protein and lysine content while BQPM-4 was better in both tryptophan and starch content. In hybrids, BAU1M-4 x K-1105 for moisture content, BQPM-2 x HKI 163 for calcium content, BQPM-2 x BAU1M-2 for iron and crude fibre contents, CM-111 x K-1105 for phosphorus content, BAU1M-4 x CM-150 for reducing sugar content and BQPM-2 x K-1105 for dry ash content were found to be good for baby corn purpose while for grain purpose, BQPM-2×BAU1M-2 was good in protein, lysine and starch contents while BQPM-4 × K-1105 in tryptophan content.
