Abstract

Psathyrostachys huashanica is a relative of wheat (Triticum aestivum L.) with many disease resistance genes that can be used to improve wheat disease resistance. In order to enrich the germplasm resources available in wheat genetics and breeding, we assessed Fusarium head blight (FHB) resistance in 45 interspecific derivatives between wheat and Psathyrostachys huashanica during two years from 2017-2018. Two interspecific derivatives comprising, H-34-8-2-6-1 and H-24-3-1-5-19-1 were identified as FHB resistant lines. These two lines were examined based on their morphology and cytogenetics, as well as by genomic in situ hybridization (GISH), fluorescence in situ hybridization (FISH), molecular markers, and 660K genotyping array to determine their genetic construction. The results confirmed H-34-8-2-6-1 as a wheat-P. huashanica 1Ns long arm ditelosomic addition line and H-24-3-1-5-19-1 as a wheat-P. huashanica 2Ns substitution line. Assessments of the agronomic traits showed that H-34-8-2-6 had significantly higher kernel number per spike and self-fertility rate than parent 7182. In addition, compared with 7182, H-24-3-1-5-19-1 had a much lower plant height while the other agronomic traits were relatively similar. The two new lines are valuable germplasm materials for breeding FHB resistance in wheat.

小麦与花沙棘豆种间衍生物的抗枯萎病鉴定及分子细胞遗传学。
华山拟小麦是小麦(Triticum aestivum L.)的亲缘植物,具有许多抗病基因,可用于提高小麦的抗病性。为了丰富小麦遗传育种的种质资源,在2017-2018年2年间,对45个小麦与花沙刺槐种间衍生物的赤霉病抗性进行了研究。两个种间衍生物h -34-8-2- 1和H-24-3-1-5-19-1被鉴定为FHB抗性品系。利用基因组原位杂交(GISH)、荧光原位杂交(FISH)、分子标记和660K基因分型阵列对这两个品系进行形态学和细胞遗传学分析,确定其遗传结构。结果证实h -34-8-2- 1 -1为小麦- p。华山芥1Ns长臂二染色体附加系与H-24-3-1-5-19-1作为小麦杂种。华山卡2Ns代换系。农艺性状评价表明,H-34-8-2-6的穗粒数和自育率显著高于亲本7182。与7182相比,H-24-3-1-5-19-1株高较低,其他农艺性状基本一致。这两个新品系为小麦抗赤霉病育种提供了宝贵的种质材料。
