摘要
对阜新地区常用的21个玉米杂交品种的籽粒产量、干物量、单株穗数、株高、倒伏系数、雌雄穗开花间隔、叶片卷曲指数、叶片衰老指数等指标进行综合考察,得出各品种的综合耐旱指数,并利用选择指数多性状综合评价品种的抗旱性,为农业生产及进一步筛选耐旱玉米种质提供参考。
This article investigated the drought resistance indexes of 21 corn hybrids including grain yield, plant dry weight, panicle number per plant, plant height, lodging coefficient, anthesis silking interval, leaf rolling index and leaf aging index in Fuxin region. The drought resistance index was obtained according to the indexes referred above, which give some references for agricultural production and further variety selection of drought resistance corn.
