| Abstract | This research aims to study the chromosome numbers and karyotypes of four banana varieties from Ratchaburi Province using the root tip squashing technique. The varieties are: Kluai Leb Mu Nang (Musa sapientum Linn.), Kluai Tani (Musa balbisiana Colla.), Kluai Namwa Tanao Sri (Musa × paradisiaca L.), and Kluai Hom Khiew (Musa sp., AAA group "Cavendish"). Chromosomes were obtained from root tips and fixed roots; meristem cells were stained with acetocarmine dye and photographed under a light microscope during the metaphase stage. Data analysis and idiogram display were conducted using Excel and Adobe Photoshop CS5. The results revealed that the chromosome number was 2n=22 for both Kluai Leb Mu Nang and Kluai Tani. For Kluai Namwa Tanao Sri and Kluai Hom Khiew, the chromosome number was 3n=33. Chromosome sizes ranged from 1.30 to 3.40 ?m. The karyotypes consisted of metacentric and submetacentric chromosomes, except for Kluai Tani and Kluai Namwa Tanao Sri, which exhibited subtelocentric chromosomes. |
