北疆冬小麦异地选择初探

[目的]提高高代定型品系工作效率.[方法]选用已稳定的小麦品系在塔城和安宁渠两点同时种植,通过对其主要农艺性进行分析,确定同点间各参试材料农艺性状与产量间的相互关系、两两之间的相关程度及两点间同一农艺性状间的相关程度.[结果]两点间在产量三要素中穗粒数对产量的贡献最大,株高和容重在两地间的相关达到了显著水平,其中容重在两点间的差异达到了极显著水平,但塔城点的株高与产量呈负相关.安宁渠点表现一般的05/7072的材料在塔城点表现较好,其平均产量在这两点位列各参试品系首位.[结论]异地种植冬小麦进行品系选择可以加快育种进程.

Primary Study on Choosing Different Areas of Winter Wheat in the North of Xinjiang

[Objective and Method]The aim of this text was mainly to study the new steady wheat lines cultivated in Tacheng and Anningqu of Xinjiang at the same time to analyse their main agronomic quality.[Result]The result showed that grain per ear had the greatest contribution to the wheat yield in different places.We expect that some theoretical basises can be provided for the selection of winter wheat breeding. The results showed that there was significant correlation between plant height and bulk density in two areas, in which the bulk density reached the extremely correlation in two areas, but there was negative correlation between plant height and yield in Tacheng.The main agronomic quality of 05/7072 was performed generally at Anningqu but better at Tacheng. The average yield of these two places ranked first in all lines. [Conclusion]Based on this result, more research will be developed for choosing different areas in the further
