利用永368(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.
