为了获得矮秆、高产稳产和适当早熟的小麦新品种,在安徽农学院激光室共同主持和协作下,近两年又继续进行了L_3、L_4代小麦激光育种试验,发现L_2变异的单株,在L_3代中有一变异株的性状得到了遗传,并继续分离,性状超亲。 In order to obtain dwarf, high and stable yield and suitable early maturing wheat variety, under the co-chair and collaboration of laser chamber of Anhui Agricultural College, the laser breeding experiments of L_3 and L_4 generations were continued in the recent two years. It was found that single plant, In the L_3 generation a mutant has been trait genetic traits, and continue to segregate, trait super progenitor.
