摘要
利用永 36 8(普通小麦 )与春品 11(白壳、六倍体小黑麦 )、人工合成小麦双二倍体、柱穗山羊草进行复合杂交 ,采用系谱法 ,按照宁夏小麦品种选育目标 ,经过连续十年的选择 ,培育出 10个稳定优良品系 ,分别为春节 1、2、3、4、5、6号和春山1、2、3、4号。它们与宁夏目前生产上的主栽品种宁春 4号所属的遗传类群不同 ,品质也有明显改进。染色体组原位杂交和醇溶蛋白电泳鉴定结果表明 ,新创造的 7个选系是黑麦染色体 1B/ 1R易位系 ,另外一个品系是涉及黑麦其他染色体的易位系。
Ten advanced wheat germplasms, named Chunjie 1, 2, 3, 4, 5 and 6 and Chunshan 1, 2, 3 and 4, came from derivatives that Yong 368 (Common wheat) hybridized with Chunpin-11 (White chaff) (Triticale) and Synthetic wheat or Ae.Cylindrica, using pedigree method. These new germplasms did not have the same genetic background of Ningchun 4, a major wheat cultivar in Ningxia now. The quality of the new germplasm was obviously improved. Chromosome in situ hybridization test and HMW-G-S analysis showed that seven of ten newly created lines had 1B/1R translocation, and one line had translocation involving other R chromosomes.
