红皮小粒油食兼用花生新品种云花生3号的选育与应用研究

目的]探讨云花生3号(Arachis hypogaea L.)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。

Breeding and Application of Yun Peanut No.3

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 cuhivar 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 maxi- mal 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.
