国家食用豆产业技术体系2019-2021年普通豇豆新品种(系)联合鉴定分析

Joint Identification of New Varieties(Lines)of Cowpea during 2019-2021 Organized by China Agricultural Research System of Food Legume

新品种的联合鉴定可以有效评估其高产、稳产及生态适应性。本研究对国家食用豆产业技术体系2019-2021年10个普通豇豆新品种(系)在14个试验点的联合鉴定试验进行了分析。结果表明,不同生态区普通豇豆的表型差异明显,其中以主茎分枝数、单株荚数和产量的变异较明显(平均变异系数均大于20%),株高、生育天数和百粒重的变异一般(平均变异系数均介于10%~20%),单荚粒数变异不明显(平均变异系数为9.93%)。最终分别筛选出4个适合北方春播区、4个适合北方夏播区及2个适合南方区种植的豇豆新品种(系)。

The combined identification of new varieties can effectively assess their high yield,stable yield and ecological adaptability.In this study,the joint identification test of ten new common cowpea varieties(lines)in 14 test sites of the National Edible Bean Industry Technology System from^(2)019 to 2021 were analyzed.The results showed that the phenotypes of different ecological common cowpea differences were obvious,the variation of the number of main stem branches,the number of pods per plant and yield were obvious(average coefficient of variation was more than 20%),the variation of plant height,growth period and 100-grain weight were generally(the average coefficient of variation between 10%-20%),and the variation of seed number per pod was not obvious(the average coefficient of variation was 9.93%).Finally,four new cowpea varieties(lines)suitable for northern spring sowing area,four suitable for northern summer sowing area,and two suitable for planting in southern China had been selected.
