Abstract

Quxian No. 15 is a new autumn vegetable soybean variety bred by crossing Tongdou No. 2006 as female parent and Xiaonongqiuyan as male parent. The growth period is 79 days. It has determinate podding habit and convergent plant type. The average plant height is 57.3 cm and the bottom pod height is 8.4 cm. There are 11.9 nodes in its main stem and 1.9 effective branches. The flowers are white, and the pod pubescence is gray. The seeds are elliptical with yellow-green seed coats. Each plant produces an average of 29.3 effective pods, with an average of 2.1 seeds per pod. The standard pod is 5.7 cm in length and 1.5 cm in width, with a standard pod rate of 68.6%. The fresh 100-pod mass is 306.5 g, and the fresh 100-seed mass is 76.7 g. The yield is about 700 kg per 667 m ². The fresh seeds have soluble sugar content of 1.5%, protein content of 118.5 g·kg^-1, starch content of 54 g·kg^-1, and fat content of 42.5 g·kg^-1. It is susceptible to SC15, medium-resistant to SC18 and medium-resistant to anthracnose. It is suitable for autumn soybean planting in Zhejiang province and regions with similar ecology.
