咸阳大穗麦84(加)79-3-1的引种研究

在福建不同生态区对陕西咸阳大穗麦84(加)7931进行了3年引种研究。结果表明,该品种为春性,其幼穗分化发育进程及生育期与福建品种类似,可以正常抽穗成熟;矮秆大穗,株高80～88cm,穗长18～20cm,每穗22～23个小穗46～48粒,千粒重50～60g,小穗排列稀疏,顶部小穗较易退化,分蘖力较弱,单株成穗数少;较耐肥,在高肥条件下产量可达6000kg·hm^-2,比对照增产20%左右;耐旱性和耐湿性较差,抗锈病,中抗白粉病,重感赤霉病;在福建沿海高产区可搭配种植,并可作为大穗亲本在育种上应用.

Introduction of large ear wheat variety Xianyang 84(Jia)79-3-1

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.
