甘蔗斑茅属间远缘杂交BC3F1品系抗倒伏性评价
Study on the Lodging Resistance of BC3F1 Lines,a Distant Hybrid between Erianthus arundinaceus and Saccharum officinarum
摘要
Abstract
[Objective]This study aims to evaluate the lodging resistance of BC3F1 progeny derived from intergeneric distant hybridization between sugarcane(Saccharum spp.)and Erianthus arundinaceus.[Methods]Based on six parameters—stem/leaf sheath weight ratio,bottom/top diameter ratio,middle/top diameter ratio,stem flexural strength,stem compressive strength,and stem tissue structure strength—a comprehensive evaluation model was established to assess the lodging resistance of 14 BC3F1 hybrid lines developed by South China Agricultural University.[Results]The results indicated that in the plant cane trial,lines'HE15-40','HE15-81','HE15-30','HE15-77','HE15-61','HE15-63'and'HE15-19'exhibited strong lodging resistance,accounting for 50.0%of the total,while'HE15-87'showed weak lodging resistance.In the ratoon cane trial,lines'HE15-63','HE15-77','HE15-61','HE15-19'and'HE15-31'demonstrated high lodging resistance,accounting for 35.7%of the total,while'HE15-84'was identified as weakly resistant.[Conclusion]Under comprehensive evaluation of both plant and ratoon crops,four lines—'HE15-77','HE15-61','HE15-63'and'HE15-19'—exhibited superior lodging resistance among the 14 tested BC3F1 progen.This study provides valuable germplasm resources and evaluation techniques for improving lodging resistance in sugarcane breeding.关键词
