四川省凉山州陆稻引种试验

Introduction Test of Upland Rice in Liangshan Prefecture of Sichuan Province

[目的]初步筛选出适宜于在凉山州高原稻作区气候环境条件下种植的陆稻品种。[方法]对引进的28个国内外陆稻品种进行田间种植，用当地常规优质粳稻品种合系22-2作对照。记录生育期、苗情动态和植株特性，测定穗部性状、田间产量和物理品质。[结果]引进的陆稻品种生育期均短于CK，在138～152d之间；有11个品种株型结构较好；各品种最高苗和有效穗都较低；L28、L26、L25、L24和L16的产量较高，比CK增产；稻谷物理品质综合表现均较差。[结论]国内选育的旱稻9号（L24）、旱稻502（L25）、旱稻297（L26）和旱稻277（L28）产量高，适应性较强，生育期比较适宜，可进入下一步的试验示范。

[Objective]The research aimed to screen out the upland rice varieties that were suitable for being grown under the climate environmental conditions in plateau rice-growling area in Liangshan Prefecture. [Method]28 introduced upland rice varieties at home and abroad were planted in the field. And the local conventional good-quality japonica rice variety 22-2 was taken as control. The growth period, seedling situations and plant characters were recorded and the ear traits, field yield and physical qualities of grains were determined. [Result]The growth period of introduced upland rice was in the range of 138 - 152 d, shorter than CK. 11 varieties had better plant-type structure of each variety were lower. The yield of L28, L26, L25, L24 and L16 were higher than CK. The physical qualities of all graim had worse comprehensive performance. [Conelasion] Upland rice varieties No. 9（L24）, 502 （L25）, 297（L26） and 277 （L28） had high yield, stronger stability, and suitable growth stage, which could be usod in the further experiment and demonstration.
