利用１９９３ ～１９９５ 年河南省粳稻区域试验及１９９６ 、１９９７ 年河南省粳稻生产示范资料，对豫粳８ 号的丰产性、稳产性和产量结构进行分析。结果表明：豫粳８ 号丰产性较好，稳产性较差。在产量三要素中，穗粒数对产量的直接作用最大，千粒重次之，有效穗数的直接作用最小。因此，在高产栽培上应在保证亩成穗２０ ～２２ 万的基础上，主攻穗粒数，并注意提高千粒重。
Based on the regional experiment of japonica rice in Henan Province from 1993 to 1995 and the demonstration data of japonica rice production in 1996 and 1997 in Henan Province, the high yield, stable yield and yield structure of Yujing 8 were analyzed. The results showed that Yujing 8 had better high yield and poor stability. Among the three elements of yield, the direct effect of grain yield per panicle was the largest, followed by 1000 grain weight, and the direct effect of effective panicle number was the smallest. Therefore, high-yielding cultivation should ensure that acres of spike 20 to 22 000, based on the main spike grain, and pay attention to improve the 1000-grain weight.
