[Method] Selection, breeding, characters, yield and the stability of Yun peanut No.3 were analyzed. [Result] Yun peanut No.3 is a new early-mature peanut species bred based on foreign resources and local varieties through sexual hybridization and improvement. It contains 50.32% of fat, 26.5% of protein, 38.93% of oleic acid, 38.88% of linoleic acid, and the ratio of oleic acid and linoleic acid is at 1.00. It is a typical small-scale peanut with red skin, high contents of oil and fat, and constitutes the first one approved by cultivar registration in China. According to related tests, pod yield achieved 3 615.9 kg/hm2 ; kernel yield was 2 570.1 kg/hm2 and oil output was 1 293.3 kg/hm2 . For the production at scale, pod yields would be about 3 000 kg/hm2 ; the production value of fruit would be 25 000 Yuan/hm2 ; the yield per unit area would be maximal at 16 000 kg/hm2 , totaling 64 000 Yuan/hm2 . It enjoys different excellent qualities, such as drought-resistance and barren-resistance. It was approved in Yunnan Province in 2012 and extended at 20 000 Yuan/hm2 in major production lands. [Conclusion] Yun peanut No.3, which is highly-yield and highly-qualified, is suitable to be grown in Yunnan, as well as similar conditions in southern regions in China.展开更多
