摘要
科辐早熟沙打旺新品种,是用 C_0^(60)—r 射线处理沙打旺干种子,诱发早熟突变选育出来的。它的特点一是早熟一个半月到近三个月;二是产粒量高;三是产草量高;四是植株形态突变。在大面积的示范推广中,充分显示了这个科辐早熟沙打旺新品种良好的生产价值。这个新品种培育和推广成功,是沙打旺育种工作的一个突破,在不久的将来,必将为我国寒冷地区的草原建设做出应有的贡献。
The new variety of early-maturing Astragalus adsurgens pall radiated is selected through treatment of the dry seeds with ^(60)Co-γ and the induction of early-maturing mutation.The nature of the new variety is,early maturing for one and half to three months;high amount of seed production;the third is high yield of grass;and the forth is the form mutation of plant.In the process of demonstrating and extension on large area the improved seed illustrated advanced value of production.The successful cultivation and extension of the variety is a breakthrough for the breeding of A.adsurgens pall.It is expected the variety would make proper contri button to the construction of grassland in the cold region of China:
