【摘要】 通过对云南省第十二轮区域试验和云南省分区育种杂交组合的家系评价、同异分析等,系统评价了云瑞05-292作为品种、亲本的应用潜力。1)与云南省第十二轮区试参试品种(系)比较,云瑞亲本育成品系云瑞05-292、云蔗06-160与本次试验综合表现最好的引进品种Sp 80-3280、Sp 81-3250和对照相当,优于其他参试的云南引进、自育品种(系); 2)云瑞05-292有效茎数多、宿根能力强,蔗茎均匀整齐,具备良好的适宜机械收获的品种应用潜力;3) 17型组合家系评价结果:云瑞05-292、云瑞05-292×云蔗05-51,云瑞99-601、CP 94-1100×云瑞99-601,云瑞10-299、ROC 6×云瑞10-299可作为高产高糖母本、父本和杂交组合利用,云瑞10-463、云蔗05-51×云瑞10-463可作为高糖育种的父本与组合应用;4)云南分区育种15型组合4点评价结果:云蔗05-51×云瑞05-292组合后代的表现良好,云瑞05-292、云蔗05-51可作为甘蔗育种的优良亲本利用。更多还原

【Abstract】 The application potential of Yunrui 05-292 as a variety and parent was systematically evaluated by family evaluation and homology analysis of the 12 th round of regional test in Yunnan Province and the regional breeding hybrid combinations in Yunnan Province. 1) Compared with the varieties(lines) tested in the 12 th round of regional test in Yunnan Province, yunrui parent lines Yunrui 05-292 and Yunzhe 06-160 were comparable to the introduced varieties Sp 80-3280 and Sp 81-3250 with the best comprehensive performance in this test, and superior to other introduced and self-bred varieties(lines) tested in Yunnan; 2) Yunrui 05-292 has a large number of effective stems, strong rooting capacity, uniform and orderly cane stems, and has good application potential for mechanical harvesting varieties; 3) Evaluation results of type 17 combination family: Yunrui 05-292, Yunrui 05-292× Yunrui 05-51, Yunrui 99-601, CP 94-1100× Yunrui 99-601, Yunrui 10-299, ROC 6× Yunrui 10-299 Yunrui 10-463, Yunzhe 05-51× Yunrui 10-463 could be used as the male parent and combination of high sugar breeding. 4) The evaluation results of type 15 combination in Yunnan Region breeding showed that yunzhe 05-51× Yunrui 05-292 had good progenies, yunrui 05-292 and Yunzhe 05-51 could be used as excellent parents in sugarcane breeding.更多还原
