摘要
选用16个玉米杂交种为材料,对各试验杂交种的产量和主要农艺性状进行调查及相关分析,结果表明,在南疆春播条件下,玉米杂交种的穗粗、株高、穗长、出籽率是影响产量的主要因素。选择抗倒伏、株高适中偏高、果穗中长、出籽率高和偏晚熟品种是提高籽粒产量的有效途径。
In this experiment, the maize hybrids developed by Institute of Grain Crops, Xinjiang Academy of Agricultural Sciences were used to investigate and analyze the grain yield and main agronomic characters of all experimental hybrids. The experimental results find that ear- width, plant height, ear- length and kernels shelling percentage are the principal factors for affecting yield of spring maize in the south Xinjiang. It was suggested that the hybrids selectee should obtain the characters of lodging resistance, mid - high plant height, mid - long ear length, high percentage of grain shelling and a bit late maturity, it is effective way to increase grain yield.
