Comparative test of hybrid rice varieties in upland in Xinping County
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.
