Forty two DH lines were selected out from 5 crosses of wheat×maize.Being compared with their wheat parents, they changed in plant height, spike numbers per plant,spike length,seed number per plant,seed weight,mature date and resistance to powder mildew.These variations were two dimensional.Dwarf lines with better agronomic characters and high resistance to powder mildews were selected out so as to be used as parents in wheat breeding.Wheat×maize method was proved valuable in haploid breeding,wheat improvement...

In order to transfer the powdery mildew resistance gene of Triticum araraticum to common wheat, T.araraticum was crossed with common wheat cultivars,and the resulting F 1 plants were selfcrossed or backcrossed to the wheat cultivars.All plants of F 1 hybrids and some of F 2 and F 3 progenies were identified to be resistant to powdery mildew.The cytological analysis showed that less than 7 pairs of bivalents per PMC at metaphase I of F 1 hybrids were observed and C banding showed that the bivalents consisted of A u and A b chromosomes. Trivalents,tetravalents and a few pentavalents were also observed in PMCs.More than 90 percent of somatic cells in the F 3 progeny had 42 chromosomes,some of which obtained the chromosomes from T.araraticum .

Chromosome 1RS/1BL was widely used in Sichuan wheat breeding. 48 cultivars possessing 1RS/1BL translocation were identified by improved Giemsa-Cbanding, and the genetic expression of gene Pm8 for resistance to powdery mildewwas carried out. These cultivars were inoculated by mildew isolate which virulence has been investigated by known resisrant gene lines. The resultsindicated: 21 of those shows absence of Pm8 resistance,24 present the Pm8 resistance and 3 would carry other gene...

Chromosome 1RS/1BL was widely used in Sichuan wheat breeding. 48 cultivars possessing 1RS/1BL translocation were identified by improved Giemsa-Cbanding, and the genetic expression of gene Pm8 for resistance to powdery mildewwas carried out. These cultivars were inoculated by mildew isolate which virulence has been investigated by known resisrant gene lines. The resultsindicated: 21 of those shows absence of Pm8 resistance,24 present the Pm8 resistance and 3 would carry other gene (s) confering the resistance to powdery mildew. It was assumed that many released cultivars which showed genetic variation of gene Pm8 made the epidemic of wheat powdery mildew in Sichuan. The exploitation of Chromosome 1RS/1BL in wheat production was also discussed in this paper.

用Giemsa-C带技术鉴定了48个含1RS/1BL染色体的小麦材料,并对其抗白粉病基因Pm8的遗传表达进行了初步研究。用对Pm8非毒性的小麦白粉菌系接种这些品系,结果表明:21个小麦品系1RS/1BL染色体上的抗白粉病基因Pm8未表达,24个具有Pm8抗性,3个品系可能含有除Pm8外的其它基因或组合。我们认为,在四川小麦中的含1RS/1BL染色体的品种(系)中Pm8基因的不表达也是白粉病流行的重要原因,在利用1RS/1BL染色体于四川小麦高产育种中应注重其抗病性,并发掘新的抗白粉病资源有重要的现实意义。
