Abstract/ Executive Summary:

The experiment was conducted at Cotton Research Farm, Jagodishpur, Jessore during the season 2011-2012 to evaluate the qualitative characteristics, seed cotton yield, cumulative % of seed cotton yield, ginning and lint of characteristics of four materials and two control varieties. Among them, four were encoded JA-08/A, JA-08/D1, JA-09/G and JA-10/J respectively. The other two were control variety CB-10 and CB-11. Significant difference was found among the treatments for the traits of vegetative branches/plant, primary fruiting branches/plant, secondary fruiting branches/plant, days to 50% flowering, days to 50% boll split, number of bolls/plant, single boll weight (g), plant height (cm) and seed cotton yield (kg/ha). The line JA-08/A performed well in terms of seed cotton yield (3441 kg/ha). The line JA-10/J produced the highest lint (1473 kg/ha) associated with the highest GOT (46.30%) percentage. The highest number of bolls/plant (42.10) was found in the line JA-08/A. The highest 2.5% span length (30.48 mm) and the lowest micronaire value (3.7) was found in the line JA-08/D1.

Keywords: Cotton, Characterization, yield contributing characters

Location: Jagadishpur, Jessore

Start Date: 2011

End Date: 2012

Program Area: Variety and Species

Commodity: Cotton

Objectives:

The objective of this study was to evaluate the yield and adaptability of collected materials of cotton.

Methodology:

The experiment was conducted at Jessore Farm during 2011-2012 to evaluate the performance of 4 strains viz. JA-08/A, JA-08/D1, JA-09/G and JA-10/J over control (CB-10 and CB-11). The unit plot size was 10m X 7.2m (8 rows/plot) and plant spacing was 90 cm x 45 cm. All chemical fertilizers were applied as per recommendation dose. All the required cultural operations regarding irrigation, weeding and plant protection measures were adopted uniformly in all the plots throughout the growing periods. Data for the studied characters were analyzed as a factorial experiment arranged in a split plot design. The Least Significant Difference (LSD) test was used to examine differences among treatment means.

Achievement/Findings:

The highest amount of seed cotton yield was produced by JA-08/A (3441 kg / ha) that was followed by JA-10/J (3182 kg / ha), JA-08/D1 (3052 kg / ha) and JA-09/G (2952 kg/ha) respectively. The four tested lines gave highest yield than the first local control CB-10. In percentage, JA-08/A produced 29%, JA-08/D1 produced 14%, JA-09/G produced 11% and JA-10/J produced 19% more yield than the first local control CB-10. But our second local control CB-11 produced the third highest seed cotton yield (3063 kg/h).
