Abstract:

Yuebiao 5 is a new conventional rice variety with disease resistance and fine grain quality. It was derived from the application of marker-assisted selection and pedigree selection, which import the blast resistant gene Pi2 into the rice variety Yuefengzhan, through backcross, selfing, agronomic trait selection and molecular marker assisted selection over years. The new variety has the following excellent characteristics: high resistance to rice blast, high yield, grain quality of GB-quality 1, lodging resistance. The resistant rate of Guangdong vantage blast population, Zhong B and Zhong C were 93.8%~100% and 92.9%~100%, respectively. It was approved by Guangdong Variety Approval Committee in May 2015, and has a good promotion application prospect.
