聊城地区辣椒品种引种比较试验OA

To meet the development needs of the pepper industry in Liaocheng and screen new early-maturing,disease-resistant and high-pungency pod pepper varieties suitable for local cultivation,a comparative experiment was conducted on three introduced varieties and three self-bred hybrid varieties by investigating their botanical and biological characteristics.The results indicated that the introduced varieties Wojiao No.1 and Taijiao No.1 had relatively short growth periods and high pungency.Taijiao No.1 possessed strong comprehensive resistance,while both varieties showed weaknesses such as weak growth vigor,poor plant uniformity and relatively low yield.In particular,Wojiao No.1 exhibited poor comprehensive disease resistance,and both varieties could be adopted as breeding materials.The introduced variety 2401 had a relatively short growth period and strong comprehensive disease resistance,with moderate performance in growth vigor,uniformity and pungency as well as ordinary yield,which could be used as both breeding material and supplementary cultivated variety.Among the three self-bred varieties,Shenjiao No.3 had the shortest growth period,displayed excellent performance in growth vigor,uniformity,pungency and comprehensive resistance,and achieved the highest yield.It is recommended to take Shenjiao No.3 as an alternative variety for further regional trial and performance observation.
