黑龙江省七份黑绿豆地方品种品质性状的鉴定与评价

Identification and Evaluation of Quality Traits of Seven Local Black Mung Bean Cultivars in Heilongjiang Province

为鉴定及筛选适宜黑龙江地区种植的优良黑绿豆地方品种,并为当地绿豆育种改良提供优异亲本。本研究对黑龙江省7份黑绿豆地方品种的外观品质、营养品质及芽用加工品质进行了系统鉴定。结果表明:望奎黑绿豆BB-3的粒长以及粒宽最大,分别为0.55 cm和0.39 cm;肇东黑绿豆BB-5的百粒重最大,为5.54 g;黑绿豆的豆芽生物产量在106.33~113.44 g之间;黑绿豆的蛋白含量在25.13%~28.48%之间;黑绿豆BB-4、BB-5及BB-6缺失66 kD亚基。综上分析,黑绿豆的营养及外观品质优于普通绿豆对照品种。其中望奎黑绿豆BB-3,肇东黑绿豆BB-6和BB-7综合农艺性状优良、商品性好,具有良好芽用特性,可作为现代工厂化豆芽产业应用的首选原料,也可作为优良亲本参与黑绿豆育种工作。SDS-PAGE分析结果表明,黑绿豆和普通绿豆种子贮藏蛋白的电泳图谱基本一致,66 kD功能蛋白亚基组成在黑绿豆品种间有显著差异。

In order to screen the excellent local varieties of black mung bean suitable for planting in Heilongjiang Province,and provide excellent parents for local mung bean breeding and improvement.Here,we identified the appearance quality trait and edible bud processing quality of 7 landraces collected from Heilongjiang Province and the protein components of black mung bean were analyzed for the first time.The results show ed that the seed length and width of BB-3 of Wangkui black mung bean were the largest,0.55 cm and 0.39 cm,respectively.The 100 seed weight of Zhaodong black mung bean BB-5 was the largest(5.54 g).The biological yield of black mung bean ranged from 106.33 g to 113.44 g.The protein content of black mung bean ranged from 25.13%to 28.48%.Black mung bean BB-4,BB-5 and BB-6 were missing 66 kD subunits.By comprehensive analysis,the nutrition and appearance quality of black mung bean was better than that of ordinary mung bean.Among them,Wangkui black mung bean BB-3,Zhaodong black mung bean BB-6 and BB-7 were black mung bean varieties with excellent comprehensive agronomic traits,good commerciality,and good sprouting characteristics,which can be used as the preferred raw material for modern factory bean sprouting industry applications.The results of SDS-PAGE analysis showed that the electrophoretic profiles of black mung bean and common mung bean seed storage proteins were basically the same,and the composition of the 66 kD functional protein subunit was significantly different between black mung bean varieties.
