我们旅大地区,无霜期短,对早熟丰产的花生品种要求比较迫切,但目前有些早熟花生品种,往往达不到完全成熟,霜来一早,便受到冻害,不但不能作种,而且严重地影响了质量。如伏花生、白沙1016两个品种在这个地区春种得130—135天,夏播得110—120天。尤其是这两个品种,作为小麦或油菜的夏播品种,更不理想。现有的四粒红和立茎小粒,作为复种品种,是可以达到成熟的。但是这两个品种粒小,产量较低。所以,如何培育出比现有品种更早熟、更高产的花生新品种,就成为科研部门的当务之急。经过几年的 In the Luda area, the frost-free period is short, and there is an urgent need for peanut varieties with high yield of early maturity. However, at present, some early-maturing peanut varieties often fail to reach full maturity. Frost comes early and frost damage sooner. Not only can it not be used as a seed but also seriously affected quality. If the peanut, white sand 1016 two varieties of spring in this area 130-135 days, summer broadcast 110-120 days. Especially these two varieties, as summer sowing varieties of wheat or rape, even less desirable. The existing four red and stem small particles, as multiple species, can reach maturity. However, these two varieties of small grain, lower yield. Therefore, how to breed more new varieties of peanuts earlier than existing varieties and higher yields has become a priority for scientific research departments. After several years
