冬小麦品种航天诱变后代性状分析
VARIATION ANALYSIS OF SPACE MUTATION IN WINTER WHEAT VARIETIES
摘要
Abstract
Seeds of eight winter wheat varieties were carried into space by satellite Shijian No.8 and returned to the earth.After years＇ consecutive planting and choices,the mutagenic effects of space condition on the the yield in the SP3 generation,high whiteness and strong gluten materials apperaed in the mutation progenies of zhoumai18 with a whiteness value of 82.9 and stability time of 80min in the SP2 and SP3 generations were studied.The results showed that the variation of phenotype in progenies could be induced,while different varieties and traits responded differently to the space conditions. The mutant frequency of Xinmai18 and Zhengmai 366 was 13.2% and 12.5% respectively.The variation was significant in plant height,ear length,yield and quality trait.Segregation and inheritance occurred in the successive progenies,most of which were tended to be stable after the selection of single ear or plant.关键词
