摘　　要：中籼稻胜优2号于1991年引进。经过试验、试种和表证示范结果，表现出高产稳产，适应性广，综合性状好等突出特点，一般每公顷产8100—8700公斤。根据试验和试种结果的综合资料进行灰色关联分析，主要性状与产量的灰色关联度排序：出糙率＞千粒重＞结实率＞穗粒数＞有效穗。经扩繁试种，从1992年种植面积0．32公顷迅速扩大到1994年1160多公顷。New variety 'Sheng-You 2' of medium - Indica rice was introduced in the autumn of 1991. Through its experiment and planting, it presented high and stable yield , wide adaptability and good synthetical traits. Generally theyield is 8100- 8700kg per hectare. According to analysis of grey relative grades, the grey relative grade's arrangingorder of main traits and yields is husked rice percentage>TGW>seed setting>number of grains per panicle>numberof effentive panicle. By means of cxperiment and seed multiplication, the planted area has reach from 0. 32 ha.of 1992 to 1160 ha.of 1994.
