摘要: 为解析黄淮麦区小麦(Triticum aestivum L.)主导品种的品质与抗性遗传基础,利用12个小麦品质、抗病、抗旱和抗穗发芽相关的KASP标记对该区99个小麦品种(系)进行检测。结果显示,品质方面,发现33份携带Glu-D1d基因编码的优质麦谷蛋白亚基5+10类型材料及39份含有Glu-A1基因编码的Ax1/Ax2*强筋单倍型材料;抗病性方面,仅12份具备Lr68叶锈病抗性基因,所有参试材料中均未检出抗赤霉病Fhb1基因;抗穗发芽检测中,TaSdr-B1a、Rio Blanco型及Hap-H抗穗发芽单倍型分别见于9份、73份及13份材料中;抗旱性方面,53份材料为COMT-3B基因的3Ba抗旱单倍型,45份为TaDREB-B1a抗旱单倍型,而89份材料为TaSST-4A基因的A2a抗旱单倍型。由此可知,黄淮麦区小麦品种中,所检测的抗旱基因分布广泛且占比较高,而抗病性方面优异单倍型占比较少,在育种策略上迫切需要强化抗病基因的引入与利用。

Abstract: To elucidate the genetic basis of quality and resistance traits in the dominant wheat (Triticum aestivum L.) varieties from the Huang-Huai wheat region, 99 wheat varieties (lines) were genotyped using 12 KASP markers related to quality, disease resistance, drought resistance and pre-harvest sprouting resistance. The results revealed that 33 materials carried the Glu-D1d gene encoding high-quality gluten subunit 5+10, and 39 materials contained the Glu-A1 gene encoding Ax1/Ax2* strong-gluten haplotype. In terms of disease resistance, only 12 materials exhibited Lr68, a leaf rust resistance gene, and none of the tested materials were found to carry the Fhb1 gene for Fusarium head blight resistantce. For sprout resistance, the haplotypes TaSdr-B1a, Rio Blanco type, and Hap-H associated with pre-harvest sprouting were detected in 9, 73, and 13 materials, respectively. In drought resistance, there were 53 materials carried 3Ba drought resistant haplotype of the COMT-3B gene, 45 materials possessed the TaDREB-B1a drought resistance haplotype, and 89 materials carried the A2a drought resistance haplotype of the TaSST-4A gene. It could be seen that the drought resistance genes detected in wheat varieties in Huang-Huai wheat region were widely distributed and accounted for a relatively high proportion, while the excellent haplotypes in disease resistance accounted for a relatively small proportion. Therefore, it was urgent to strengthen the introduction and utilization of disease resistance genes in breeding strategies.

Key words: wheat(Triticum aestivum L.), quality, disease resistance, drought resistance, pre-harvest sprouting resistance, gene detection, KASP genotyping technology, Huang-Huai wheat region
