摘要：

通过杂交及不完全回交，结合分子标记辅助选择，育成携带广谱抗稻瘟病基因Pigm的粳稻新品种扬农粳3091。选育过程中的稻瘟病抗性鉴定结果显示，携带Pigm基因品系的抗性水平显著好于对照。该品种于2021年通过江苏省农作物品种审定委员会审定，具有综合抗性好、品质优、丰产稳产性好等特点。本文介绍了该品种的选育过程、特征特性及主要栽培技术要点。

Abstract:

Through incomplete backcross breeding and molecular marker-assisted selection, a new japonica rice variety ‘Yangnonggeng 3091’ was bred containing Pigm, a broad-spectrum resistance gene to rice blast. In the program developing the variety, all rice lines with Pigm presented well resistance to blast disease. Besides of blast resistance, Yangnonggeng 3091 was showed well agronomic characteristics, elite grain quality, high and stable yield, and authorized by Jiangsu Crop Variety Approval Committee in 2021. In this paper, the breeding process, agronomic characteristics and cultivation methods of Yangnonggeng 3091 was introduced.

Key words: japonica rice, molecular marker-assisted selection, rice blast, breeding
