EVALUATION OF SOME QUALITATIVE AND QUANTITATIVE CHARACTERS OF TEN SUGARCANE GENOTYPES UNDER WATER-LOGGING STRESS CONDITION

Abstract

A field experiment was conducted at Bangladesh Sugarcane Research Institute (BSRI) farm, Ishurdi- 6620, Pabna, Bangladesh during 2009-2010 cropping season to evaluate some qualitative and quantitative characters of ten sugarcane genotypes under waterlogging stress condition. The genotypes were I 124-00, I 112-01, I 7-03, I 78-03, I 111-03, I 137-03, I 231-03, and water-logging commercial varieties Isd 39 (Standard) and Isd 40 (Standard). Significantly highest number of tillers was recorded in genotype I 231-03 (137.73 × 103 ha-1) and highest number of millable cane was recorded in variety Isd 39 (99.76 × 103 ha-1). The significantly highest cane yield was obtained in variety Isd 39 (98.04 t ha-1), and the lowest cane yield was obtained in genotype I 111-03 (51.83 t ha-1). Significantly highest Brix per cent, highest pol per cent juice, highest pol per cent cane, highest purity per cent, highest recoverable sucrose per cent were found in genotype I 124- 00 under water-logging stress condition, respectively. The highest sugar yields was obtained in variety Isd 39 (10.88 t ha-1) followed by variety Isd 40 (10.49 t ha-1), genotype I 231-03 (10.22 t ha-1) and the lowest was genotype I 139-03 (5.47 t ha-1). Genotype I 231-03, Isd 39 and Isd 40 are highly tolerant having tolerance rating scale 1 against induced water-logging stress condition. Thus, the genotype I 231-03 proved highly potential tolerant in respect of cane yield, sugar yield, juice quality and utilization of potentiality breeding as parents to evolve varieties resistant to waterlogging.
