1、生态学杂志ChineseJournalofEcology2014,33(1):59—64豫北盐碱地引种红麻杂交种试验初报水张新董娜刘明久潘兹亮一(河南科技学院生命科技学院,河南新乡453003;河南省信阳市农业科学院,河南信阳464000)摘要为了筛选适合豫北盐碱地种植的高产红麻杂交组合,本研究以H318为对照,比较了栽培在盐碱土壤上的6对红麻杂交组合F代和F代的11个性状,分析了各个材料各个性状的竞争优势,F代和F代性状的平均竞争优势、显著性、相关性以及F:代性状相对于F代的衰退率。结果表明:
2、因组合不同,F代与Fz代各个性状的竞争优势差异较大,F:代显著衰退,但少数组合F:代仍具有一定利用价值;F代与F代间皮厚、鲜皮晒干率和鲜茎出麻率3个性状上存在极显著正相关;若以收获红麻全杆为目的,则F代以组合F3A/992、F代以组合F3A/R7为最佳;若以收获红麻纤维为目的,则F代以组合P3A/R1、F2代以组合P3A/992为最佳。关键词盐碱地;红麻;引种;杂交种中图分类号Q143文献标识码A文章编号1000-4890(2014)1-0059—06Theintroductionofkenaf
