Morphological and agronomic characterization of existing mandarin (<cirtrus reticulata bianco) germplasm

Abstract

Abstract : An investigation was carried out in Sylhet, Moulvibazar, Panchagarh and Bandarban districts from September 2009 to December 2011 with a view to characterize and evaluate the existing mandarin germplasm. Twenty nine mandarin genotypes were studied of which twenty one were Khasi and eight were Nagpuri type. Wavy type of leaf lamina margin was observed in three genotypes of Khasi type (CR-Pan 017, CR- Pan 018 and CR-Pan 020) collected from Panchagarh. The number of fruits per plant ranged from 322 to 1270 in Khasi type and 415 to 960 in Nagpuri type. The highest fruit weight was 181.64 g in Khasi and 168.80 g in Nagpuri type. The genotype CR- Mou 002 of Khasi type and CR-Mou 003 of Nagpuri type produced the largest fruit. The number of segments varied from eight to eleven. Three years average yield per plant ranged from 25.15 kg in CR-Pan 023 to 184.42 kg in CR-Pan 023. BARI Komala- 1 (Khasi type) yielded 76.27 kg fruits per plant. Total Soluble Solids close to or more than BARI Komala-1 (8.66%) in Khasi genotypes were CR-Mou 004, CR-Mou 008, CR-Syl 010, CR-Mou 012, CR-Pan 017 and CR-Pan 018 and Nagpuri genotypes were CR-Mou 003, CR-Ban 027 and CR-Ban 030. The genotypes CR-Pan 017 and CR-Pan 018 of Panchagarh were assuming Daijeeling cultivars. Among the 29 genotypes, CR- Mou 008, CR-Syl 012, CR-Pan 017 and CR-Pan 018 of Khasi type and CR-Ban 027 and CR-Ban 030 of Nagpuri type were tasted well.
