Abstract:
Objective A new high-yield, high-quality soybean variety for fresh bean consumption was bred through sexual hybridization of pedigrees and cultivated in regional trials to determine production performances.
Method Hybridized by using Fuxian 5 as the female parent and Yundou 9 as the male parent, a pedigree line coded 08B3-1 was generated. In the spring of 2013 trial, the newly bred variety demonstrated yield traits and bean quality significantly higher than those of the reference, Maodou 3. It was then named Mindou 7 and submitted for demonstration in the annual regional trials in the province on new soybean varieties for fresh bean consumption.
Result In the 2013 trial, Mindou 7 showed an average fresh pod yield of 11 459.40 kg·hm−2, which was 2.25% higher than that of Maodou 3. In the subsequent provincial regional trials in 2015 and 2016, it delivered an average fresh pod yield of 9 625.50 kg·hm−2, which was 1.76% higher than that of Maodou 3. Again, in 2017, the yield was 9 780.45 kg·hm−2, impressively 5.68% higher than that of control. The new variety was approved and released by the Fujian Provincial Committee of Crop Variety Identification in April 2018.
Conclusion The mid-season-maturation Mindou 7, with its large pods and beans, palatable taste and flavor as well as tender texture after cooking, was considered a premium variety for fresh soybean consumption and suitable for spring planting in Fujian.
