花生用种量大,繁殖系数低,一般繁殖1亩良种只能供7—8亩大田使用,因此,一个新品种育成后往往要经3—5年时间的繁殖,才能满足推广需要,致使花生新品种推广缓慢、使用年限缩短。针对这一情况,我们于1988—1991年在蓬安县清溪、红旗乡进行了花生新品系836—1的高倍快速繁殖试验示范,收到了显著效果。1991年经省组织 Peanut seed with large, low coefficient of multiplication, the general breeding 1 acre of seed can only be used for 7-8 acres of field, therefore, after breeding a new variety often 3-5 years of breeding, in order to meet the promotion needs, resulting in peanuts The promotion of new varieties is slow, the useful life is shortened. In response to this situation, we conducted a high-speed rapid propagation experiment demonstration of a new peanut line 836-1 in Qingyi, Hongqi Township, Peng’an County from 1988 to 1991, and achieved remarkable results. In 1991 by the provincial organization
