Online published: 2022-11-17
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
