Abstract EN
Sugarcane is the main sugar producing crop in Bangladesh.
However, improvement of this crop through breeding is limited due to lack of genetic diversity.
Therefore, genetic variability and diversity assessment are necessarily important for the foreign introduced materials.
Experiment was conducted with 9 exotic sugarcane genotypes at Regional Station, Bangladesh Sugar Crop Research Institute, Gazipur, during 2012-13, following RCBD.
Data were collected on different growth and yield contributing characters.
Individual cane weight exhibited high genotypic coefficient of variation and phenotypic coefficient of variation.
Leaf blade length, leaf blade width, fresh leaf weight, dried leaf weight, number of tillers, millable cane, bud size, cane diameter, internodes number, internode length, plant height, stalk length, brix%, and individual cane weight showed high heritability.
Individual cane weight showed highly significant and positive correlation with cane diameter, internode length, and stalk length, whereas path coefficient analysis revealed that cane diameter had maximum positive direct effect on individual cane weight followed by internode length, number of tillers, and chlorophyll content.
Results indicate that the genotypes should be selected on the basis of individual cane weight, cane diameter, and millable canes number for future breeding to get higher sugarcane yield in respect to juice and brix content.
