自1978年起,我所开展了食用豆类品种资源的搜集、保存、鉴定、利用的研究,现在不少省(区市)的农科院也开展了此项研究。据不完全统计,全国保存国内、外食用豆类品种资源13,000多份,我所保存近4,080份。大部分品种经1—3年试种,对其植物形态和主要农艺性状作了田间和室内鉴定,并从中选出一些优良品种提供生产试种。食用豆类属豆科,蝶形花亚科。我所近4,000份品种按植物分类学分为8个属15个种,现将在北京种植的果结分述如下:(本文标本图见封底)一、豌豆(Pisum safivum L.)又名寒豆、麦豆,春播生育期80—116天。蔓生和直立型、花色白或紫,籽粒有白、黄、灰绿、褐等色,粒形有圆、凹圆皱,
Since 1978, I conducted research on the collection, preservation, identification and utilization of legume variety resources. Nowadays, many provinces (autonomous regions and municipalities) have conducted this research. According to incomplete statistics, more than 13,000 domestic and overseas leguminous materials were conserved, and nearly 4,080 were kept by me. Most of the cultivars were field-tested and indoor-identified for their plant morphology and major agronomic traits after 1-3 years of trial cultivation, and selected some good varieties to provide production trials. Legumes are legumes, butterfly flower subfamily. Nearly 4,000 varieties of my class are classified into 8 genera and 15 species according to their plant taxonomy. The fruits now planted in Beijing are described as follows: (See the back cover of this paper) I. Pisum safivum L. , Wheat, spring sowing period of 80-116 days.
