Abstract: Three years studies on the introduction of large ear wheat variety Xianyang84(Jia)79 31 in different ecological areas of Fujian Province show that the variety belonged to springiness type which was similar to the local cultivars of Fujian Province in differentiation procedure of young ear and growing period. The variety had normal heading and maturity, and had dwarfed stems and large ears, with a 80～88cm of plant height and 18～20cm of ear length. There were 22～23 spikelets and 46～48 grains per spike, and 55～60g per 1000 grains. The spikelets had a low density, top spikelets were easy to degrade, and the plant had a weaker tillering capacity and less productive ears. The plants had a stronger tolerance to fertilization, and the yield could attain6000 kg per hectare, about 20% more than that of check cultivar under fertile condition. The tolerance to moisture and drought was weak, and strong to rust, medium to powdery mildew and seriously susceptible to scab. Xianyang84(Jia)79 31 could be planted in high-yield fields of coastal area in Fujian Province, and be applied in breeding as large ear parent.
