Studies On Transfer Effect Of Low-ALA Character In Flax

The qualitative analysis of linolenic content of the 5th generation of hybridization in 290 strains and the 4th generation of backcross in 178 strains has been determined in this study. The group of the 5th generation of hybridization and the 4th generation of backcross,the strains that contain linolenic beyond 5% are 235 and 74 respectively, their percentage in group are 81.03 and 41.57 respectively. The study indicated that genic character of low linolenic content imported from E1747 can genetic by means of sexual hybridization. The test results of one-thousand-grain weight and fatty content are :The one-thousand-grain weight and fatty content in the group of the 5th generation of hybridization and 4th generation of backcross are remarkably higher than the initial E1747 and accessing to or a little bit higher than high linolenic content parents. The quantitative analysis result of different fatty acid determined by GLC technology indicated that correlative exited in the five sorts of fat acid .The correlativity of linolenic content and one-thousand-grain weight is positive. There is no remarkable correlativity between linolenic and fatty content.
