Abstract:

The new variety test of rice is the key process of screening and identification breeding varieties, and the yield is an important index to measure the superiority of varieties. In this paper, two group regional rice varieties of Hunan Province, early rice and one-cropping late rice, were used as materials to analyze the effects of water content in grain on rice yield. The results showed that the water content of early rice and late rice directly affected the yield of each variety, and the difference between the two methods was significant. According to the standard water content, the method of unified conversion of yield could effectively avoid the influence of various factors on yield and truly reflect the yield of each variety.

Key words: rice, regional test, water content, yield
