    摘要:

    2015-2020 年,依托“第三次全国农作物种质资源普查与收集行动”,对重庆 35 个涉农区县进行普查征集与系统调 查收集。通过对收集到的蔬菜资源分布情况、生物学分类等进行整理和分析,并经田间初步鉴定。结果表明,本次资源调查共 获得蔬菜种质资源 428 份,隶属 14 科,30 属,35 种。主要分布在渝东北三峡库区及主城都市区,海拔 800 m 以上蔬菜资源占 51.17%,多在人口密度 500 人 /km2 以下地区分布,豆类、瓜类、芥菜类蔬菜资源数量占比最大。通过对各类蔬菜资源的鉴定评 价,分别筛选出在高产、抗病虫、抗逆、优质等方面表现优异的资源 64 份,其中有 6 份适宜大面积推广,分别是三元丝瓜、冬寒 菜、脚板苕、丁家儿菜、青草坝萝卜、酒罐萝卜。本研究结果将为重庆蔬菜种质资源多样性研究、种质创新、新品种选育提供基 础。

    Abstract:

    From 2015 to 2020,relying on The Third National General Survey and Collection Action on Crop Germplasm Resources,Thirty-five agriculture-related in Chongqing districts and counties were surveyed. The distribution and biological classification of vegetable germplasm resources collected were analyzed. A total of 428 vegetable germplasm accessions from 35 species of 30 genera of 14 families were obtained. These germplasm accessions were mainly distributed at the three Gorges Reservoir area and the main urban areas of northeast Chongqing,accounting for 51.17% above 800 meters above sea level. Most of them were distributed in areas with a population density of less than 500 people /km2 . Beans,melons and mustard accounted for the largest proportion. Through the identification and evaluation, sixty-four resources with excellent performance in high yield, resistance to diseases and insects,and stress resistance were screened out,of which six were suitable for cultivation with potentially commercial interest,namely Sanyuan luffa,Malva,Dioscorea alata L.,Dingjia cardamine, Qingcaoba radish,Wine jug radish . This study will provide data support for the research on the diversity of vegetable germplasm resources,germplasm innovation,and new variety breeding in Chongqing municipality of China.
