Identification, evaluation and cluster analysis of 72 cigar tobacco germplasm resources
摘要
Abstract
In order to select high quality sigar tobacco germplasm resources for breeding, field experiments using 72 cigar tobacco germplasm resources were conducted in Dehong, Yunan Province. Results revealed that, PA Swarr Hibshman was the highest yielding, followed by Glessnor. Havana 142 was the highest in upper and middle class tobacco leave proportion, followed by Havana 263. Most germplasm resources had better quality of facial appearance, and several of them had medium quality of facial appearance. Potasslum content ranged from 1.82% to 5.75%, and K2O/Cl- from 6.47 to 44.23. Oredr of coefficient of chemical indicants is as follows, ratio of Sugar-nicotine > ratio of nitrogen-nicotine > Difference of total sugar and reducing sugar > nicotine > reducing sugar > total sugar >ratio of potassium-chlorine > chlorine > potassium > total nitrogen content. As for sense of smoking, Havana 142, Little Hill, Havana 211 had top quality, and the rest had better or medium quality. Coefficient of polyphenol contents was in the following order, chlorogenic acid > neochlorogenicacid > cryptochlorogenin acid > scopoletin content > rutin contents. 72 cigar germplasm resources were classified into 5 groups by cluster analysis, cigar binde in groups 1 and 2, cigar wrapper in groups 3 and 4, cigar filler in group 3、4、5. Field experiment and data analysiscan help to group tobacco germplasm and can be used in variety breeding. Five germplasm resources showed PVY resistance, and ten were immune to TMV, three resistance to TMV, and one resistance to black shank.关键词
