| 摘 要： | 对中国扁茎大豆进行了8年产量试验,评价其产量表现和稳产性以及确定其在生产中直接利用的可能性;对中国扁茎与普通大豆品种的10个杂交组合进行了后代观察和选择,以确定抗倒伏性和扁茎性状的遗传方式及选择方法;对后代品系和育成品种进行了产量试验,以确定中国扁茎大豆在育种中的利用价值。结果表明,中国扁茎大豆的产量为1 830～2 296 kg/hm2,仅为对照品种九农21的76%～79%,在5～9月份降水量多于430 mm以上地区不宜推广种植。只要普通大豆亲本秆强抗倒伏,后代就可以出现抗倒伏有所提高又具有高丰产性能的植株材料,但抗倒伏性难以达到目标。但选用晚熟且抗倒伏的引17作亲本与中国扁茎大豆杂交,后代中出现了大量抗倒伏性符合育种目标要求且丰产的材料。连续选择扁茎株的效果很明显,可获得比中国扁茎更为稳定的扁茎系统。已有2个品种通过审定.新品系平安1020在雨量少、日照很充足、有灌溉的条件下,获得了5 802 kg/hm2的高产。98-4032、00-6023和01-5171新品系的平均产量都超过对照品种,并具有较好的稳产性。获得了一批抗倒伏性强且高产的后代材料。 |

| Abstract: | The yield tests of fasciated soybean were conducted for eight years to determine its yield performance,yield stability and possibility to be used in production.Observation and selection of offspring from ten crosses between fasciated soybean and common soybean cultivars were conducted to determine inheritance pattern and selection method of resistance to lodging and fasciated characteristic.Yield experiments of breeding lines and new cultivars were conducted to determine applied value of fasciated soybean in China in breeding.The results showed that seed yield of fasciated soybean of China was 1830-2296 kg/hm2 and 76%-79% of check cultivar ’Jiunong 9’.Its commercial planting was unsuitable in area that had more 430mm precipitation between May and Sept.When common soybean variety parent was resistant to lodging,their offspring had middle resistance to lodging and good seed yield characteristics,but the resistance to lodging could not meet the requirement.When a late maturing variety with good resistance to lodging ’Yin 17’ was used as parent and crossed with fasciated soybean of China,a large number of offspring that had good resistance to lodging and good yield characters appeared.Effectiveness of continuous selection for fasciated character was very obvious and more stable fasciated lines than haricot soybean of China could be obtained.Two cultivars were examined and approved.A new strain ’Pingan 1020’ had highest yield of 5802 kg/hm2 in area of less precipitation,adequate light and irrigation.Average yield of three new strains,98-4032,00-6023 and 01-5171 were all higher and stable yield than check variety.A lot of progeny materials with good seed yield and good resistance to lodging were obtained. |
