摘要 粤标5号是应用分子标记辅助选择与系谱选育相结合的方法,将稻瘟病广谱抗病基因Pi2导入粤丰占中,经多代选择育成的优质抗病常规水稻新品种。该品种高抗稻瘟病,对广东的优势菌群中B、中C的抗性频率分别为93.8%~100%、92.9%~100%,丰产性较好,米质达国标优质1级,抗倒性强。2015年5月通过广东省农作物新品种审定。 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 P/2 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.
