Abstract:

In order to breed new mung bean variety with strong adaptability, drought tolerance and continuous cropping tolerance, ‘Jin mung bean No. 4’ and ‘Tongyu mung bean’ were taken as the female parent and the male parent respectively for hybridization in the Institute of Industrial Crops, Shanxi Agricultural University in 2008. ‘Fen mung bean No. 4’ was bred by the way of ‘continuous planting high pressure stress method’ in the generational directive breeding process. In the production test, the yield of ‘Fen mung bean No.4’ was 11.1% higher than that of ‘Jin mung bean No.3’, and the variety was approved by the Shanxi Crop Variety Approval Committee in January 2021. The new variety ‘Fen mung bean No.4’ has good nutritional characteristics, such as high protein, low fat, medium starch, etc. At the same time, the functional components (such as vitexin and isovitexin) could provide medicated diet function. The breeding of the new variety provides a choice for medicine homologous food.

Key words: drought tolerance, continuous cropping tolerance, mung bean, new variety, ‘Fen mung bean No.4’
