太空诱变紫花苜蓿SP1代表型性状变异研究
|
摘要
利用太空特殊环境对植物的诱变作用,选择4个紫花苜蓿品种(德福、德宝、阿尔冈金、三得利)进行航天搭载太空诱变,以回归地面种植的第一代(SP1)为研究对象,通过田间表型性状变异研究,初步确定了6类变异类型;通过变异集团分类及单株优选,优选出6类变异集团57株变异单株(速生单株17株、分枝强单株11株、大叶单株4株、多叶单株6株、叶色变浓单株5株、抗逆单株14株),为紫花苜蓿新品种的选育提供形态学依据和种质材料。
By using the mutation effect of space special environment on plant,four alfalfas were selected to board on spacecraft for mutation. Taking the test materials of seed cultivation SP1 generation as the research object,we found 6 types of mutation after field observation of phenotypic variation. By means of further group classification and single optimization,we selected 57 variation plants such as fast-growing plants( 17),dwarfing-strong branch plants( 11),big area plants( 4),multifoliate plants( 6),leaf color deeped plants( 5),and stress resistance plants( 14). The research would provide a morphological basement and the germplasm resources to the further breeding of new alfalfa cultivar.
