摘　　要：介绍了特优航2号参加福建省区试、生产试验以及在龙海示范种植的表现。调查了特优航2号不同产量水平的产量构成,明确有效穗与产量的相关最密切,对产量直接通径系数最高,对产量贡献率最大;其次为每穗总粒数,有效穗与每穗总粒数对产量的贡献率占4个构成因素总贡献率的86.39%。据此提出特优航2号高产栽培技术。We introduced yield performance of a hybrid rice combination Teyouhang No.2 based on the data from regional test and produce test of Fujian province and planting performance at Longhai city. Its yield components under different yield levels were investigated. The results showed that the effective panicle had a very closely relation to yield, whose direct path coefficient and contribution rate to the yield was both the highest; the second was total spikelets per panicle. The contribution rate of effective panicle and total spikelets per panicle to yield accounted for 86.39% of total contribution rate among 4 yield components. Thus we put forward high-yielding cultivation techniques for this cultivar.
