摘要
通过对已育成的3 个绿豆品种的比较分析,认为抗旱、早熟、丰产是育成品种的主要特点。由株荚数、基茎粗、百粒重和荚粒数构成的选择指数对丰产性的选择十分有效。抗旱指数是抗旱性和丰产性的有机结合,杂交育种是提高丰产性的关键。
In this article, three mungbeen varieties,namely Qindou No.2, Qindou No.4 and Qindou No.6 were compared. It was found that the main characteristics of these three varieties were early maturing, drought resistant and high yielding. The select index was constituted by No. of peds of per plant, basic stem diameter, weight of per 100 seeds and No. of seeds of per pod. The index of drought resistance lies in yield increase and drought resistance. The hybrid breeding is the main measure for mungbean breeding.
