Abstract:

The grey correlative degree analysis was conducted to comprehensive evaluate eight main indicators of eight Mungbean varieties including yield, pods per plant, grain number per pod, 100-seed weight, etc. The results showed that ‘Xilv1’, ‘Luohai18’ and ‘Jinlvdou6’ all had larger correlative degrees which were respectively 0.7422 , 0.7288 and 0.6642, better comprehensive characters with the reference variety and higher yield, pods per plant and grain number per pod. ‘Jinlvdou1’ and ‘Jinlvdou4’ were the worst grey correlative degree which were respectively 0.5405 and 0.5122 and all indexes were lower than average. These were consistent with actual performance of the varieties and could be the main criterions in the variety extension.
