摘要
采用灰色关联分析方法研究了 6个小麦品种 8个主要农艺性状与抗旱性之间的关系 ,结果表明 ,关联度大小依次为不育小穗 >小穗数 >千粒重 >穗下节长 >穗粒数 >有效穗数 >株高 >最高群体 ;在选育抗旱性品种时应适当提高株高 ,最高群体 ,同时注意有效穗数、穗粒数、穗下节长的选择 ;品种抗旱性强弱依次为豫麦 4 8号 >洛旱 2号 >豫麦 2号 >晋麦 5 4>豫麦 4 9>豫麦18。
Gray relationship analyse was produced in wheat between eight major agricultural characters and fighting a drought . The results showed relationship degree: no-raise-spicule>spicule-number>kilo-grain weight>stem length under spike>spikes per plant>efficiency spike>plant height>tiptop colony. When selecting wheat variety of fighting a drought,we should properly improve plant height,tiptop colony,and should pay attention to efficiency spike,spikes per plant,stem length under spike as well.Wheat varieties of fighting a drought:Yumai 48>Luohan 2>Yumai 2>Jinmai 54>Yumai 49>Yumai 18.
