籼型香糯新品种滇新10号的选育

Breeding and Cultivating of New Fragrant and Glutinous Rice Variety "Dian Xin 10"

籼型香糯新品种——滇新10号是云南农业大学稻作所利用籼粳亚种间和地理远缘间的品种杂交,经8代选育而成的高产、优质、抗病的新品种。亩产量在425～666公斤,比当地糯谷品种增产12.76％～212.42％。目前已在云南、四川、安徽,湖北等省大面积推广应用。本文着重介绍了籼型香糯——滇新10号的选育过程特征、特性及其栽培技术要点。现将结果概述如下:

Through eight generations a new frangrant and glutinous rice variety—'Dian Xin 10' was developed by crossing from the Rice Reseach Institute of Yunnan Agricultural University. The crossing was done between two subspecific rice varieties of Indica and japonica, which were also with far geographic relationship. The Variety, with high potentail yield, good quality and resistance to diseases, has been extended in many provinces (Yunnan, Sichuan, Anhui Hubei etc.) . The yield is ranged 425～660 kg per mu, and is 12.76%～212.42% higher than the local varieties. This paper stresses the breeding method of the variety and its agronomic characteristics and cultivation.
