Comparative test of 6 Helianthus tuberosus L.varieties(lines)in Qinghai province
In this study,the plant height,stem diameter,water content,tuber yield,soluble sugar con-tent,germination rate and storage tolerance of 6 cultivars(lines)of Jerusalem artichoke(JA)were evalua-ted.The results showed that the yield and soluble sugar of treatment 3-1 were the highest(81.0 t/hm2,20.4％),the crude protein content of treatment 6-1 was the highest(2.6％),and the crude fiber content of treatment 5-1 was the highest(1.5％).Qingyu No.1 and Qingyu No.5 were early maturing JA varie-ties,Qingyu No.3,249,Yu No.1 and Yu No.2 were late maturing varieties.The varieties with the highest germination rate were Qingyu No.1 and Qingyu No.3,all of which were 95％.Compared to other potato va-rieties(lines),Qingyu 1 had the lowest decay rate.This provids excellent germplasm resources for the subse-quent breeding of new varieties and promoting the development of JA industry.
