摘要
本研究于1985、1986两年将我国北方小豆主产区地方品种92份及长江下游地方品种4份夏播于南京农业大学,1990年将我国北方小豆主产区地方品种275份及江淮流域地方品种11份夏播于北京农学院(北纬40度)进行观察。本文主要以1990年北京观察的生育期性状就该地区的参试地方品种进行了生态分类,并讨论了该地区的生态类型分布。(1)将生育前期(播种~开花)由35天以内的极早(Ⅰ)到56天以上的极晚(Ⅵ)划分为6个水平,生育后期(开花~成熟)由35天以内的极短(a)到51天以上的极长(e)划分为5个水平。所有参试品种可归为22类群。(2)河北省区域(包括北京、天津)内生态类群多,遗传资源最丰富,以此为中心地带相距越远的地域其类群数越少,江苏、山东、黑龙江生态类群较单一。
92 local varieties of adzuki bean that producted at north china
and 4 local varieties of lower reaches of chang jiang were planted at
Nanjing Agricultural University in summer in 1985-1986. In 1990, 275 local
verieties of adzuki bean that producted at north .china and 11 local varieties
of chang jiang and Huai he valley were planted in Summer at Beijing
Agricutural College (40°) and were abserved. This article is about the
ecological classify of local varieties of that their growth duration characters
were observed in 1990 in Beijing and discussed the ecological type
distribution at Beijing area.
(1) Take the earliest that the earlier growth duration (Plant-flowering
period) is within 35 days (Ⅰ) and the latest is above 56 days (Ⅳ) devided
into 6 levels. take the shortest that later growth duration (flowering
period-reaping is within 35 days (a) and the longest is above 51 days (e)
devided into 5 levels. Take all test varieties devided into 22 groups. (2)
In Hebei province region (include Beijing. Tan jin) ecological groups are
more, heredity resources were the richest. centure in the region the distance
is the farther, the groups is less. The ecological groups are more simple at
Jiang su, Shan dong and Hei Long jing province.
