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 combination of molecular marker-assisted selection and pedigree breeding method. The broad-spectrum resistance gene Pi2 of rice blast is introduced into Yuefengzhanzhong, and the new variety of conventional rice with high quality and disease resistance has been bred by many generations. This variety is highly resistant to rice blast, and the frequency of resistance to B and C in dominant populations of Guangdong are 93.8% -100% and 92.9% -100%, respectively, with high yield and good quality. Inverted strong. In May 2015, it passed the examination of new crop varieties in Guangdong Province.
