长粒香型优质高产粳稻新品种云粳39号选育及栽培技术

Breeding and Cultivation Technology of Long-grain and Quasi-aromatic Japonica Rice Yunjing 39 with Good Quality and High Yield

云粳39号是云南省农业科学院粮食作物研究所选育的长粒香型优质高产粳稻新品种,杂交组合为合系41号、云粳20号。2011~2012年参加云南省中海拔粳稻区域试验,平均产量为10 440.00 kg/hm2,较对照云粳26号增产7.90%。2013年参加云南省生产试验,平均产量为10 207.50 kg/hm2,较对照云粳26号增产5.06%。该品种具有优质、高产、稳产、抗病等优点,适宜在云南省海拔1 450~1 850 m稻区及周边省份相似生态型稻区推广种植。2014年通过云南省农作物品种委员会审定。该研究介绍了云粳39号的选育经过、特征特性及栽培技术要点。

Yunjing 39, a hew long-grain, quasi-aromatic, good quality and high yield Japonica rice variety, was bred by Food Crops Institute, Yunnan Academy of Agricultural Sciences, derived from Hexi 41/Yunjing 20. In Yunnan middle-altitude territorial experimentation during 2011- 2012, the average yield of Yunjing 39 was 10 440.00 kg/hm3, higher than Yunjing 26 by 7.90%. In the pilot production test in 2013, the aver- age yield of Yunjing 39 was 10 207.50 kg/hm3, higher than Yunjing 26 by 5.06%. Yunjing 39, which has the characteristic of good quality, high yield, stably high-yield ability, strong resistance to diseases, is suitable for the cultivation in the altitude ranges from 1 450 to 1 850 m in Ymman Japonica rice planted area and surrounding provinces with similar ecotype in China. It was certified by the Variety Certification Committee of Yunnan Province in 2014. The breeding process, characteristics and cultivation technique key points of Yunjing 39 were introduced.
