为解决我市原主栽芸豆品种中存在的豆荚商品性差、产量低、熟性晚、豆荚易老化等问题,我所科技人员于1986～1994年从国内外征集大量的芸豆品种试材,进行了分批分期试种观察,品比试验,筛选出熟性早、品质好的芸芸丰(623),1990年进行成果鉴定并应用于生产。在此基础上,对86-77、86-1、86-66等试材进行分离选种,选出优良变异单株,扩大繁植,从14个株系优中选优,经3～4年春秋季品比试验和多点试种、示范,决选出优质高产大荚型86-77-4,代号77,其特点为单荚重,商品性好,无筋,风味品质佳。3年平均亩产达2682.5kg,比对照品种增产31.5％。同时以同样的方法决选出适于秋季种植的芸豆新品系86-66-2,代号66,其特点是抗病性强,结荚多,品质好,亩产1500kg左右,比对照品种增产24.6％。1994年底经本省市同行专家对该项研究
In order to solve the problems of poor quality, low yield, late maturity and easy aging of pods in the original planted kidney bean varieties of our city, our scientists collected a large number of kidney bean cultivars from 1986 and 1994, Batches were observed in batches in phases, the ratio test, screened Yun-Feng Feng (623) of early maturity, good quality, in 1990 the results were identified and applied to the production. On this basis, 86-77, 86-1, 86-66 and other materials were isolated and selected, select the excellent mutant single plant, expand the plant, selected from 14 strains of excellent, by 3 to 4 years of spring Autumn than the test and more trial, demonstration, decided to select high-quality large-yield pod 86-77-4, code 77, which is characterized by a single pod weight, good commercial, non-gluten, good flavor quality. 3-year average yield of 2682.5kg per mu, an increase of 31.5% over the control varieties. At the same time, the same method for selecting a new kidney bean line 86-66-2 suitable for planting in autumn, code 66, which is characterized by strong disease resistance, pod and more, good quality, about 1500kg per mu, 24.6 more than the control varieties %. By the end of 1994 by the provinces and cities counterparts on the study
