摘  要:
矮败小麦是太谷核不育基因m s2和矮秆基因Rht10的紧密连锁体,是一种具有矮秆性状标记的显性核不育新材料,是小麦遗传改良极为有效的工具,利用它特别适用于多亲本聚合杂交和轮回选择育种,简化并加速了小麦种质创新和新品种选育进程,经过十几年的潜心研究,已育成一批各具特色的优异种质及优良品系。通过高产超高产基础群体组建及群体改良,成功选育出品2、品4、品7、品10、品13及品14等优良超高产品系,其中,品2平均产量达到8307.0 kg/hm2,比对照增产21%,品7平均产量达到8 244.0 kg/hm2,比对照增产20%。

摘  要:
Dwarf male-sterile wheat is a linkage body with Taigu genic male-sterile gene ms2 and dwarf gene Rht10.It is a new dominant male sterility material with dwarf marker and an effective tool process wheat genic improvement.It especially fit to the multi-parents polymeric cross and recurrent selection breeding.Thereby it can accelerate the progress of wheat germ plasm innovation and cultivation of new varieties.After study for tens years,we have bred a great mount of excellent breeds and strains.Such as PIN2,PIN4,PIN7, PIN10,PIN13 and PIN14 are the super high yield strains.The yields of PIN2 reach 8 307.0 kg/hm2,over CK 21%;and the PIN7 is 8 244.0 kg/hm2,over CK 20%.
