Identification and analyses of 22 purple yam germplasm resources
摘要
Abstract
[Purpose]Local germplasm resources of purple yam with high yield,disease resistance,and high quality was screened to provide a basis for development and variety improvement.[Method]The yield,agronomic traits,disease resistance,and com-mercializing ability of 22 purple yam germplasm resources were investigated.Statistical and correlation analyses of agronomic traits were identified,and key factors of yield were determined.[Result]There were significant differences of agronomic traits among pur-ple yam tested,and the coefficients of variation for the seven main agronomic traits ranged from 7.83%to 52.78%.Genetic diversity among the 22 purple yam germplasm resources was extremely high.Correlation analysis revealed significant positive correlations a-mong tuber mass,tuber length,tuber diameter,leaf length,and leaf width.Disease resistance analysis showed that there were sig-nificant differences in the field resistance of 22 purple yam germplasm to anthrax,and half of them were not resistant to anthrax.[Conclusion]Nanchang purple yam,Guigang purple yam,and Ziyu Huaishan performed well,with an output of more than 30 000 kg·hm-2.They were resistant to anthrax,had a good taste,and had good commercial properties,suitable for further promotion.关键词
