Productivity has not been increasing at the rate for production to keep pace with population growth. One of the main reasons of this is the unavailability of suitable high yielding maize genotypes. The yield potential of composites is low, so the ninth five-year plan has stated that there is a need for hybrid maize, especially for the areas where high inputs are available. Therefore, the Agriculture Botany Division, Khumaltar is evaluating local as well as exotic germplasm for hybrid development in collaboration with the National Maize Research Programme (NMRP), Rampur and the International Maize and Wheat Improvement Center (CIMMYT), Mexico. During the last three years, a number of inbred lines and hybrid trials from different sources were evaluated at Khumaltar. Most of the hybrids yielded more than 10 ton ha-l, whereas some of the hybrids yielded as much as 14 ton ha-l. CML 287 X CML 323, CML 226 X CML 295, NC 300 X CML 323 and NC 300 X CML 295 were the highest yielders, whereas NC 300 X CML 323 was earliest in maturity and shortest in plant height. Inbred lines of superior hybrids were evaluated. CML series 20, 223, 226, 287, 295, 323, 324, 327, 329 and NC 300 inbred lines were promising in combining ability and agronomical characters, and they will be used for developing hybrids in the future.Collection: CIMMYT Publications Collection
