Abstract:

Zhenong 16 is a new spring vegetable soybean variety bred through sexual hybridization using Zhenong 8 as the female parent and JP55 as the male parent. This article provided a detailed introduction to the breeding process of Zhenong 16,its regional trial performance,characteristic traits,and key seed propagation techniques,aiming to offer references for large-scale application and promotion of Zhenong 16. Results showed that in the regional trial of fresh spring soybeans in Zhejiang Province from 2020 to 2021,the average growth period of Zhenong 16 was 81.6 days. The plant height of Zhenong 16 was 30.3 cm,main stem node was 7.7,and effective number of branches was 3.2. There were 28.4 effective pods per plant,with a standard pod rate of 70.6%. The number of seeds per pod was 2.0. Fresh hundred pods weigh was 311.1 g,and fresh hundred seeds weight was 73.8 g;The seeds were circular in shape,the seed coat was light green,and the cotyledons were yellow. Besides,Zhenong 16 had high resistance to mosaic virus disease SC15 and SC18 strains,and were susceptible to anthracnose. The average fresh pod yield per 667 m2 was 827.0 kg in the regional test of fresh spring soybeans of Zhejiang Province in 2020 and 2021,and the average fresh pod yield per 667 m2 was 824.4 kg in the production test of fresh spring soybeans of Zhejiang Province. This variety is suitable for spring planting in Zhejiang and surrounding areas with similar climate.
