STUDY ON ASSESSMENT OF CLIMATE RISK FOR SEED-BREEDING BASE AREA OF BILINEAR HYBRID RICE

The climate risk for seed-breeding of bilinear hybrid rice is defined on the basis of Jiangxi geographical data on the scale of 1:250000, climate data in 40 years of 84 observatory stations and analysis of the relationship between climate factors and height above sea level, using spatial analyzing method of GIS. The climate risk for seed breeding of bilinear hybrid rice is assessed and the best region and season for seed-breeding is sought. It is important to agricultural production. Analyzing results were proved by the production practice.
