Abstract:

Ningzi 3 is a late-maturing and high-yielding new variety of Chinese milk vetch, selected by Zhejiang Wuwangnong Seeds Sharehooding Co., Ltd. This variety was systematically selected through pedigree analysis, based on the domestic Chinese milk vetch variety Ningbo Daqiao as the basic population, and variant individuals with late maturity and thick stems were selected. After years of self breeding for agronomic and quality traits, targeted breeding was carried out. The average fresh grass yield of this variety in the two-year multi-point adaptability test is 56 877.9 kg·hm^-2, which is 21.5% higher than the control Ningbo Daqiao variety. During the flowering period, the crude protein content were 19.5%, crude fiber content was 25.50%, crude fat content was 31.4 g·kg^-1, nitrogen content was 3.12%, phosphorus content was 2.02 g·kg^-1, and potassium content was 42.7 g·kg^-1. In 2022, it was recognized as a non major crop variety in Zhejiang Province [Zhejiang Recognition Fertilizer 2022001] and is suitable for planting in Zhejiang Province.
