伴生小麦的生物学和遗传学特性研究

摘要：调查研究了伴生小麦的生物学和其遗传特性，并应用A-PAGE方法对普通小麦和伴生小麦进行醇溶蛋白遗传分析。结果表明：伴生小麦植株高，茎杆细，分蘖多，分蘖成穗率高，叶片细长，穗粒数30-35粒左右，千粒重20-30g左右，种子休眠期通常比小麦长，伴生小麦为自花授粉作物，与小麦杂交能够结实，有42条染色体，醇溶蛋白遗传分析表明，伴生小麦属于普通小麦类型。

Studies on the Characteristics of Biological and Genetics of Semi-wheat

Wheat yields were affected by the semi-wheat that grew in wheat field. Experiment was conducted to study on the characteristics of biological and genetics of semi-wheat. The gliadin composition of common wheat and sime-wheat was analyzed by A-PAGE. The results showed that the plant height of the semi-wheat was taller than cultivated winter wheat cultivars,the stalk diameter was slender,the numbers of tiller was more,earbearing tiller percentage was higher. The numbers of seeds per ear were nearly 30-35. 1000-seeds weight of semi-wheat were nearly 20-30 g. Seeds dormancy was more time than winter wheat. Semi-wheat was self-pollinating species. It could product seeds that sime-wheat had been crossed with varieties of wheat. The number of chromosomes of sime-wheat was 42. The sime-wheat belongs to wheat species.
