Abstract:

Zhehua 6 is a new high oleic acid peanut variety, which is a combination of Huayu 52 as the female parent and Xiaojingsheng as the male parent, and the hybrid offspring were selected and bred according to the genealogical method and multi-generation directional screening. It has the characteristics of high and stable yield, outstanding early maturity, strong lodging resistance and wide adaptability. This variety participated in the regional experiment in Zhejiang Province from 2020 to 2021, with an average pod yield of 4 074.00 kg·hm-2 and an average seed kernel yield of 3 040.58 kg·hm-2, which were increased by 36.4% and 47.5% respectively compared with the control Xiaojingsheng. In 2020, its protein content was 22.0%, oleic acid content was 77.9%, linoleic acid content was 4.74%, and the ratio of oleric acid to linoleic acid was 16.43, which were detected by Hangzhou Center of Inspection and Testing for Quality and Safety of Agricultural and Processed Products, Ministry of Agriculture and Rural Affairs, P.R. China. This variety showed moderate resistance to leaf spot, bacterial wilt and rust, and had been registered as a national non-major crop variety in 2023. It is currently the first high oleic acid edible peanut new variety developed in Zhejiang Province. Zhehua 6 has high and stable yield, outstanding early maturity, tolerance to continuous cropping, and excellent comprehensive characters, and is suitable for spring and summer planting in the ecological area of the middle and lower reaches of the Yangtze River in Zhejiang Province.
