ABSTRACT
The experiment was conducted at Cotton Research Center, Jagadishpur, Jessore, Bangladesh during the season 2018-2019 to evaluate the qualitative characteristics, seed cotton yield, cumulative % of seed cotton yield, ginning and lint of characteristics of five materials and control variety CB-14. Among them, five were encoded JA-16/1, JA-17/1, JA-08/5, JA-16/2 and JA-17/2 respectively. The other was control variety CB-14. Significant difference was found among the genotypes for the traits of vegetative branches/plant, node number of first fruiting branches/plant, primary fruiting branches/plant, secondary fruiting branches/plant, days to 50% flowering, bolls/plant, single boll weight (g), plant height (cm), yield (kg/ha). The line JA-17/2 produced the highest seed cotton yield (4278 kg/ha) and highest lint (1720 kg/ha) than the control variety CB-14. The line JA-17/2 also showed the highest GOT (40.20%) percentage. Among the five tested entries and control variety CB-14, the highest upper half mean length (31.80 mm) was found in the line JA-17/1. The highest strength (34.70 g/tex) value was found in the line JA-16/2 and the lowest micronaire value (3.56) was found in the line JA-16/1.
Keywords: Cotton genotypes, Qualitative characters, Agronomic and yield contributing characters, GOT%, Lint characteristics.
