国家食用豆产业技术体系绿豆新品种(系)联合鉴定

Multi-Loci Identifications on New Varieties(Lines) of Mungbean from China Agriculture Research System on Food Legume

分析了国家食用豆产业技术体系2016-2017年24个绿豆新品种(系)在20个试验点的鉴定结果,以期为新品种(系)的进一步示范推广提供参考。结果显示,不同生态区绿豆表型差异明显,以株高、主茎分枝数、单株荚数和单株产量的变异最明显(平均变异系数均介于20%~40%),单荚粒数、百粒重、生育期变异不明显(平均变异系数均介于10%~20%)。综合分析发现,冀绿0816、JLPX02、品绿2011-06的生态适应性最广,在20个参试点均适宜种植,适应性最差的为苏绿16-10,仅在江苏南京能够正常生长成熟。根据表型及产量表现,分别筛选出适宜不同生态区种植的绿豆新品种(系),为这些品种(系)的进一步示范推广奠定基础。

To accelerate the promotion and application of 24 new varieties(lines)of mungbean,phenotypic evaluation were made in 20 loci in the year of 2016 and 2017.The results showed that the phenotypic variations of mungbean were obvious in different ecological zones.Plant height,number of branches per main stem,pods per plant and yield per plant showed wide genetic variances with the average coefficient of variation at 20%-40%,while the variances on seeds per pod,100-grain weight and growth period were fairly narrow with the average coefficient of variation lower than 20%.Jilü0816,JLPX02 and Pinlü2011-06 had the widest ecological adaptability.These three varieties can be applied in all the tested sites,while Sulü16-10 had the narrowest adaptability,and only can be planted in Nanjing and around.According to the phenotype and yield performance,varieties suitable for planting in different ecological areas were screened,laying a foundation for further demonstration and popularization of these varieties.
