【摘要】 对具有黑麦细胞质的春小麦核质杂种阿齐佩格、普通小麦埃尼塔和异核型核质杂交种阿齐佩格×埃尼塔的 F1代在干旱条件下抗旱生理特性和产量因子进行分析。研究表明 ,干旱处理后异核型核质杂种一代在产量方面具有显著优势 ,同核型核质杂种 (阿齐佩格 )生长势强于对照品种。这表明黑麦细胞质在一定程度上具有抵御短期干旱的能力 ,由核质杂交种与地方抗旱品种杂交选配可成为小麦抗旱高产育种的有效途径。更多还原

【Abstract】 The characteristics of drought resistant physiology and yield trait of nucleus cytoplasm hybrid wheat with rye type cytoplasm (АЦПГ),wheat(Энита)and allonucleus hybrid АЦПГ(♀)×Энита(♂) F 1 were studied. The results indicated that after drought stress treatment, allonucleus hybrid had significant superior in yield index. The growing potential of АЦПГ higher than the control cultivar Энита.This shows that rye type cytoplasm have the ability to resist short time drought in certain degrees. The cross of wheat nucleus cytoplasm hybrid with the local fine varieties might be an effective way for breeding of wheat with drought resistance and high grain yield.更多还原
