福建省地方优良果蔗染色体分带的研究

Studies on the Chromosome Banding Technique of Fine Chewing Cane in Fujian Province

摘要: 应用改进的F-BSG法,对福建省地方优良果蔗同安果蔗、马鞍果蔗、浦城果蔗和崇安果蔗的根尖染色体进行分带处理。它们的染色体数2n均为80,属热带种(Saccharum officinarum L.).除马鞍果蔗染色体的基本带型为6C/CT+74C/C以外,其余三个果蔗品种的基本带型均为5C/CT+75C/C.

Abstract: A modified F-BSG technique was applied to chromosome banding investigation on four fine chewing cane varieties i.e.Tong-an, Ma-an,Pu-cheng and Chong-an chewing cane varieties in Fujian province.Theirchromosome numbers in root tips are 2n=80, belong to Saccharum officinarum L..The chromosome basic handing types are 5 C/CT+75 C/C except that Ma-an chewing cane is 6 C/CT+74 C/C.
