Abstract：With large seed variety (Xianghua 2008)and small seed variety (Hunan agriculture floret born)as materials,using the data of total solar radiation,rainfall,evaporation capacity,temperature,the peanut climate production potential was estimated at 4 major peanut planting areas in Hunan Province (Shaoyang, Shaodong,Dao and Mayang County).The results showed that the climate production potential of large seed peanut was significantly higher than that of small seed one.The main restriction eco -factor of peanut yield was temperature at sowing to seedling,seedling and pod development stages.At flowering stage,the main re-striction eco -factor of peanut yield was water in south central and northwest of Hunan Province.The climate production potential use ratios were very low.The actual peanut yield was less than 30% of climate production potential both in Dao and Mayang County.Hunan peanut yield had very big rise space,which provided a theo-retical basis for high yield variety breeding and high yield cultivation techniques.
