Study on Environmental Sensitivity of Variety in Rice
Study on Environmental Sensitivity of Variety in Rice
摘要
Abstract
According to sensitivity to environment, rice varieties can be classified into a strong environmentally sensitive variety, a weak environmentally sensitive variety and an environmentally insensitive variety.The general method that was used to evaluate the environmental sensitivity (ES) of rice variety was put forward in this paper. ESs of varieties were evaluated as follows: (1)ES of indica-japonica hybird rice was more sensitive than that of japonica rice. (2)The order of ESs of japonica type varieties was medium-maturing late japonica variety ＞ early-maturing late japonica variety ＞ late-maturing medium japonica variety ＞ medium-maturing medium japonica variety. (3)There was a significant difference in ESs among varieties of the same japonica type rice, too. Some problems, such as the principles of rather late-maturing rice planted northward,were also discussed at the end of this paper.关键词
