摘要
以日本引进的125份稻种资源为材料，进行主要农艺性状的分析评价，结果表明：播抽期以90-120d的居多，占总数的90．4％；株高变化幅度在60．5—197．4cm之间，偏高株型主要集中于籼稻和爪哇稻；穗长变幅在9．54—31．86cm之间，总趋势是爪哇稻〉籼稻〉粳稻。品种间产量差异极显著。幅度在8349．26-2571．05kg／hm^2之间．最高为粳稻W132（越光），平均8349．26kg／hm^2。筛选出W132、W155等24份材料在株型、产量构成因素、生育期等综合农艺性状较为理想的优良品种资源。
The main agronomy of 125 rice varieties introduced from Japan was analyzed and evaluated in the article. It was concluded that the sow - heading days of rice range mainly from 90 to 120 days and it occupied 90.4%. The length of rice plants ranged from 60. 5 to 194. 7cm and the higher length of plants were mainly Indicia and Java type Panicle. The length of rice plants ranged between 9.54cm and 31.86cm, and the total tendency was that the length of Japonica type was the longest, followed by Indicia type and then Japonica type. The yield of different varieties was extremely remarkable, ranging from 8349.25 to 2571.05 kg/hm^2. The highest average yield of W132 （Japonica type） was 8349.26kg/hm^2.24 rice varieties included W132, W155 were chosen as ideal and eminent rice resources according to plant shape, yield, growth duration etc.
