Abstract:

Abstract: 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 20~30g. Seeds dormancy was more time than winter wheat. Semi-wheat was self-pollinating species.It can product seeds that sime-wheat had been crossed with varieties of wheat.The number of chromosomes of sime-wheat was 42.The sime-wheat belong to wheat species.
