Evaluation of Nine Maize varieties for Intervarietal Hybridization

Abstract

The technical difficulties in the production of double cross hybrids have been a serious problem for slow coverage of the total maize area under cultivation. The evaluation of inbreds makes the procedure costly. The development of the varietal hybrids seems to be a quick approach to ensure the high yields of maize in comparatively short time and with the least expenditure. The heterosis expressed by the genetically diverse varietal crosses can be exploited and the success of which will depend on the efficiency with which the superior varietal crosses can be detected.
