The early maturing, good yielding, high quality, disease resistance, drought tolcrance, cold endurance and wide-yanging adaptiveness are the important characteristics of the variety, which showed remarkable increases in yield and profit in the several large production areas of Fujian. During 1991-1993,its accumulative extension area, increased output dry product and added profit were amounted to 56 993.4 hm2,146 000 ton and 147.0 million yuan respectively. |
