[目的]选育出适合我国南方生态气候条件种植的珍珠豆型高油酸花生新品种,为南方花生产区高油酸花生生产发展提供优良品种.[方法]将从美国引进的高油酸种质SunOleic 95R分别与我国珍珠豆型高产、抗病品种汕油162、粤油13和粤油45进行杂交,从杂交后代材料中筛选得到符合育种目标的高油酸品系,并进行区域试验和生产试验.[结果]选育的桂花37属珍珠豆型花生品种,油酸含量82.90%,亚油酸含量2.60%,油亚比（O/L）32.34,且高抗青枯病、抗叶斑病和锈病.在国家（南方片）花生区域试验和广西花生品种区域试验中,荚果产量分别为3670.35和3814.05 kg/ha,分别比对照品种（汕油523和桂花21）减产6.02%和2.26%;在广西北流生产试验中,平均荚果产量5570.70 kg/ha,与所有参试品种的平均产量（5550.36 kg/ha）相比,桂花37增产0.37%.2016年6月桂花37通过广西农作物品种审定委员会审定.[结论]选育的珍珠豆型花生新品种桂花37的油酸含量高且抗病性强,适合在我国南方花生产区推广种植.

英文摘要：

[Objective]The present study aimed to breed Arachis hypogea L. var. vulgaris new varieties which could adapt to eco-climate conditions in southern China, and provide superior varieties for development of high-oleic-acid peanut in southern peanut planting areas. [Method]High-oleic-acid germplasm SunOleic 95R was brought in from America and crossed with three local A. hypogea L. var. vulgaris high-yield and disease resistent varieties（Shanyou 162, Yueyou 13 and Yueyou 45）. The strains with high oleic acid were selected from the offsprings for breeding, and regional trials and planting trials were conducted. [Result]Guihua 37 was a bred A. hypogea L. var. vulgaris variety with 82.90% oleic acid content, 2.60% linoleic acid content and oleic acid-linoleic acid ratio（O/L） being 32.34. It was highly resistant to bacteria wilt, leaf spot and leaf rust. In national（southern） trials and Guangxi regional trials for peanut planting areas, the pod yields were 3670.35 and 3814.05 kg/ha respectively, which were decreased by 6.02% and 2.26% compared with control （Shanyou 523 and Guihua 21）. In Beiliu planting trial, the average yield was 5570.70 kg/ha, which increased by 0.37%compared with the average of other tested varieties（5550.36 kg/ha）. In June, 2016, Guihua 37 was approved by Guangxi Crop Variety Approval Committee. [Conclusion]Guihua 37, a new variety of A. hypogea L. var. vulgaris containing high oleic acid content and resistance to diseases, is adaptive to peanut planting areas in southern China.
