New Mung Bean Varieties(lines)in Henan Province:Comparison and Analysis of Combined Identification Test
摘要
Abstract
Aiming at the problems of slow variety renewal and insufficient yield stability in the main producing areas of mung bean in Henan Province,this study was conducted through multi-point joint identification of Zhengzhou,Nanyang,Luoyang and Anyang to screen out the high and stable yield mung bean varieties suitable for planting in Henan Province,and to provide theoretical reference for breeding improvement and market promotion.The new mung bean lines in the joint identification test of new mung bean varieties in Henan Province from 2019 to 2020 were used as test materials,and the field performance,yield results and agronomic traits in test sites were compared by statistical analysis.The average yields of'Zhenglyu 19','Zhenglyu 20','Anhuang mung bean 2'and'Wanlyu 7'in two years were 1936.80 kg/hm2,2219.03 kg/hm2,2009.40 kg/hm2,1971.38 kg/hm2,respectively.Compared with the control variety'Zhenglyu 8',the yield was increased by 3.18%,18.21%,7.04%and 5.02%,respectively.The average yield of'Wanheilyu 1'and'Wanlyu F9'was 1661.70 kg/hm2 and 1503.68 kg/hm2,respectively,which was 11.48%and 19.90%lower than that of'Zhenglyu 8'.The coefficient of variation of pod number per plant was the largest in the agronomic traits of the tested mung bean lines,which was 20.43%.The variation coefficient of growth period was the smallest,only 3.77%.The results of correlation analysis showed that the yield was significantly positively correlated with the number of pods per plant,significantly negatively correlated with the growth period and the number of nodes on the main stem.The number of pods per plant was significantly positively correlated with the main stem branch,and significantly negatively correlated with the growth period.Plant height was significantly positively correlated with the number of main stem nodes and significantly negatively correlated with pod length.In summary,the four mung bean lines such as'Zhenglyu 19'in this study were relatively stable in Henan Province,and had certain promotion value and application value,which provided a theoretical basis for the breeding of new mung bean varieties and the utilization of germplasm resources.关键词
