Effects of Location on Performance of Selected Tropical Maize Hybrids Developed in Malaysia

Eighteen selected locally-developed maize hybrids involving ten single, four double and four three-way crosses were evaluated with two open-pollinated check varieties (Metro and Suwan 1) at three locations in Peninsular Malaysia. The study was aimed to compare performance among the hybrids at the...
