Objective   A high-yield, high-quality, disease-resistant peanut variety was bred, and its growth characteristics and cultivation in Fujian studied.

  Method   Years of directional selection were carried out by crossing between the high-yield, high-quality peanut Xianghua 120 as female parent and the disease-resistant Quanhua No. 10 as male parent. The final hybrid cultivar obtained was subjected to field trials and the spring peanut regional tests in Fujian.

  Results   In the provincial tests from 2015 to 2016, the newly bred Puhua 45 showed a pod yield of 3 787.05 kg·hm⁻² and a kernel yield of 2 559.00 kg·hm⁻², which were 9.09% and 7.69% higher, respectively, than those of the reference. Nutritionally, it contained 53.08% crude fat, 26.3% protein, 47.8% oleic acid, 31.6% linoleic acid, and with an O/L ratio of 1.51. Compact in plant type and upright on standing, Puhua 45 grew with vigor and was moderately resistant to bacterial wilt, rust, and leaf spot. It had passed the national non-major crop variety registrationGPA(2019)350271 in January 2021. Its outstanding physiological and agronomical characteristics that were superior to the reference included the more concentrated blooming period and pods per plant, and the higher effective flowering rate, leaf area index, net assimilation rate, chlorophyll content, and dry matter accumulation.

  Conclusion   In addition to high-yield, high-quality, and disease-resistance, Puhua 45 exhibited many desirable properties and should be promoted for peanut cultivation in Fujian.
