[Objective] The aim was to explore the production potential and extension value of Yun peanut No.3 to lay foundation for further extension.[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,26.50％ 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 peanut with high contents of oil and fat,and constitutes the only 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 production 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 regions in China.%[目的]探讨云花生3号(Arachis hypogaeaL.)的生产潜力和推广价值,为其进一步大面积推广奠定基础.[方法]介绍云花生3号的选育经过、特征特性,并分析其产量表现及其稳定性.[结果]云花生3号是利用外国资源与云南地方品种、通过人工有性杂交和改良系谱法育成的早熟优质花生新品种.其粗脂肪含量50.32％,蛋白质含量26.50％,油酸含量38.93％,亚油酸含量38.88％,油亚比1.00,属典型的红皮小粒高含油量高蛋白质花生品种,也是我国至今唯一通过品种审定(登记)的红皮小粒花生品种.多点试验中,荚果产量3 615.9 kg/hm2,仁产量2 570.1 kg/hm2,产油量1 293.3 kg/hm2,大面积生产一般荚果产量3 000 kg/hm2左右,鲜食产值达2.5万元/hm2左右,最高鲜花生单产1.6万余kg/hm2,产值6.4万元/hm2,并表现抗旱、耐瘠、适宜套作等优良特性,于2012年通过云南省品种认定.已在云南各主要花生产区推广应用2万hm2以上,并引进贵州、海南等省种植,显示出良好的应用前景.[结论]云花生3号中早熟、高产、品质优,适宜云南全省种植,也可在我国南方条件类似花生产区种植.
