本文报导了如何选育大豆高产品种问题。通过研究发现,目前有些大豆品种在生产上有倒伏现象,为提高大豆产量,必须选育秆强不倒的品种。有两个途径可达上述目的,一是选育矮秆和半矮秆的大豆品种,大豆矮源的产生有四种:1.利用有限结荚习性品种和无限结荚习性品种杂交;2.有限结荚习性品种之间进行杂交,3.用钴60等射线处理有限结荚习性的大豆,4.农家品种中的涹秆材料。应用上述方法已选出一些大豆矮秆半矮秆品系。二是对高秆大豆后代用高肥水条件进行筛选,从巾已选出秆强不倒高产的新品种黑农26,该品种己在黑龙江省南部地区推广二百多万亩。
This article reports on how to breed high-yield soybean varieties. Through research, we found that some soybean varieties have the phenomenon of lodging in production at present. In order to increase the yield of soybean, it is necessary to breed breeds with strong stubbornness. There are two ways to achieve the above objectives. One is the selection of dwarfing and semi-dwarfing soybean varieties. There are four types of soybean dwarf sources: 1) the combination of limited sowing varieties and unlimited sowing varieties; 2. Limited hybridization between crossed varieties, 3. treatment of limited pod habitat with cobalt rays such as cobalt 60, 4. stalk material in peasant varieties. Some soybean dwarf dwarf lines have been selected using the above method. Second, the high-stalk soybean offspring with high fertilizer conditions were selected from the towel has been selected to breed strong non-yielding new varieties of black peasants 26, the species has been in Heilongjiang Province to promote the southern region of more than two million mu.
