EVALUATION OF HIGH OIL HYBRIDS OF MAIZE

摘要

Heterosis for grain yield, oil. and protein was studied in ten high oil maize hybrids obtained after crossing the oil lines. R 802, R 805 and R 806 introduced from USA with Indian lines viz., CM 119, CM 201, CM 201. CM 202 and the composite. Harsha. The studies were made over the standard check DHM-105. For grain yield, the hybrids HOH-8, HOH-2, HOH-5 and HOH-10 have shown significantly level heterosis. while the hybrids HOH-3. HOH-6 and HOH-9 were significantly superior to the standard check, DHM-105 in oil content. Simultaneous increases in yield, oil and starch were observed in HOH-2 and HOH-5, while HOH-8 recorded more protein than DHM-105. Hybrids, HOH-2, HOH-5 HOH-8, HOH-9 and HOH-10 can be recommended for further evaluation at several locations as yield, oil, protein and starch arc reported to be greatly influenced by both genotype and environment.
