新平县杂交稻旱种品比试验

Comparative test of hybrid rice varieties in upland in Xinping County

为筛选适宜云南新平地区的具有较强旱种适应性的杂交稻品种,本研究选择滇禾优34、滇禾优55和滇禾优56等14个杂交稻品种进行同田展示比较试验。结果表明,品种滇禾优56、云粳39、滇禾优615、滇禾优55、滇禾优34和滇杂31能够正常成熟,其他8个杂交稻品种未抽穗;正常成熟的6个品种中,滇禾优56、云粳39和滇禾优615的生育期适中,抗性较好,产量构成协调,产量较高,旱种适应性较好,可作为旱种杂交稻品种在研究区推广种植。

In order to screen hybrid rice varieties with strong drought adaptability suitable for the Xinping area of Yunnan Province,this research selected 14 hybrid rice varieties,including Dianheyou 34,Dianheyou 55,and Dianheyou 56,for field display comparative experiments.The results showed that varieties Dianheyou 56,Yunjing 39,Dianheyou 615,Dianheyou 55,Dianheyou 34,and Dianza 31 could mature normally,while the other 8 hybrid rice varieties did not tassel.Among the six normally mature varieties,Dianheyou 56,Yunjing 39,and Dianheyou 615 had a moderate growth period,good resistance,coordinated yield composition,and high yield.They had good adaptability to drought and could be promoted and planted as drought hybrid rice varieties in the research region.
