水分高效利用抗旱小麦品种筛选研究

Studies on Wheat Cultivars Screening for Drought Resistance and High Water Use Efficiency

通过旱棚和大田对12个旱地小麦品种进行了抗旱鉴定和水分利用效率评价。试验结果表明,按照抗旱指数将12个品种分为4个类型:运旱23-35、运旱22-33属于极强类型;西农928、运旱21-30、洛旱2号、临旱51329、长6359和晋麦47属于中等类型;运旱20410、衡水7228属于弱类型;临旱51241、洛麦9769属于极弱类型。筛选出水分高效利用抗旱品种运旱23-35、运旱22-33、临旱51329、晋麦47等4个品种。

The exprienment was conducted to evaluate resistant drought and water use efficiency of 12 wheat cultivars under field and water-free shellter conditions.The results showed that 12 wheat cultivars were devided into four types according to drought resistance index.Yunhan 23-35 and Yuhan 22-33 were highly resistant,Xinong 928,Yunhan 21-30,Luohan 2,Linhan 51329,Chang 6359 and Jinmai 47 were moderately resistant.Yunhan 20410 and Hengshui 7228 were susceptible.Linhan 51241 and Luomai 9769 were highly susceptible.Yunhan 23-35,Yuhan 22-33,Linhan 51329 and Jinmai 47 were high water use efficiency wheat cultivars.
