摘　　要：以 5个同质异核二角型小麦雄性不育系 ms( bicor) - 82 2 2、ms( bicor) - 83( 37) 65、ms( bicor) -偃师 9号、ms( bicor) - 80 ( 6)及 ms( bicor) - 90 - 1 1 0为基本材料 ,与一批优良小麦品种(系 )及部分亲本材料为父本进行测交 ,获得 2 1 1个组合 ,考察其 F1育性 ,结果表明 :( 1 ) 5个同质异核不育系 ,除二角型非 1 B/1 R不育系 ms( bicor) - 90 - 1 1 0与二角型 1 B/1 R不育系 ms( bicor) - 83( 37) 65、ms( bicor) -偃师 9号之间平均恢复度差异显著外 ,4个 1 B/1 R不育系之间平均结实率差异不显著 ;( 2 )对同一不育系而言 ,与不同恢复系测交 ,其恢复度呈现连续变异 ;( 3)同型非 1 B/1 R不育系较 1 B/1 R不育系恢复度普遍高 ;( 4 )对同一恢复系而言 ,各不育系测交The fertility of 211 hybrids (F 1) derived from five male sterile lines of wheat with Ae.bicornis Cytoplasm,namely ms(bicor) 8222,ms(bicor) 83(37)65,ms(bicor) yanshi 9,ms(bicor) 80(6)and ms(bicor) 90 110,with some wheat varieties or lines and partial parent materials was inverstigated.The result showed that:(1) In the five male sterile lines,with different nucleus,of wheat with Ae.bicornis cytoplasm there was obvious difference of restoring degree between the non 1B/1R wheat male sterile lines ms(bicor) 90 110 and the 1BL/1RS wheat male sterile lines ms(bicor) 83(37)65,ms(bicor) Yanshi 9,while there was no obvious difference between the four 1B/1R male sterile lines each other,(2) As the same male sterile line tested crossing with different restoration lines,the restoration degree showed successive variation;(3) The restoration degree of non 1B/1R male sterile lines were higher than that of 1B/1R male sterile lines,(4) As the same restoration lines,there was obvious difference between each hybrids (F 1) derived from tested crossing.
