Investigation,collection and evaluation of local long cowpea germplasm resources in Guangxi
摘要
Abstract
During 2015 to 2020,relying on the ministry of agriculture special"the third National Crop Germplasm survey and collection action"and Guangxi innovation driven development project"Guangxi crop germplasm resources collec-tion,identification and preservation"two projects,the agricultural and rural affairs bureaus of various counties in Guangxi and the Guangxi academy of agricultural sciences conducted systematic surveys,collections,and field evaluations of veg-etable germplasm resources throughout the regrion.The results showed that a total of 1997 vegetable resources were col-lected,including 150 local long cowpeas resources from 45 counties(cities,districts)in 13 cities.The germplasm resourc-es of long cowpea were mainly distributed in Guilin(northern Guangxi),Baise(western Guangxi)and Hezhou(southeast-ern Guangxi).Among them,Babu district,Zhongshan county,Mashan county,Cenxi city and Jingxi city were the five dis-tricts/counties with the highest concentration of cowpea resources.Long cowpea resources were predominantly found in low-altitude hilly and mountainous areas at an altitude of 0-300 m,accounting for 55.3%of the total collected.All 145 identified resources were vegetable-use long cowpea,all of which were of the soft pod type.Among them,91.7%were vining type,75.2%were early-medium maturing type,51.0%had light green pods,and 57.9%had young pod length less than 50 cm.Further identification revealed that 10 long-pea resources,including Hezhou Early Beans,Liuzhou Green Beans,Guilin Long Beans,Nanning Sweet Beans,and Guilin Autumn Wind Beans,exhibited excellent traits in aspects such as early maturity,high yield,disease resistance,and high quality,holding significant breeding potential and applica-tion value.This study systematically analyzed and evaluated the basic characteristics and elite germplasm of Guangxi cowpea resources,providing a scientific basis for the in-depth exploration and innovative utilization of cowpea germ-plasm resources.关键词
