Abstract/ Executive Summary:

An experiment was carried out with five advanced lines (BC -051, BC-0165, BC-0406, JA/2000/526 and BC-0342) and two commercial check varieties (CB-9 and CB- 10) to observe the yield potentiality and response to different environment and to select the best line. This experiment was laid out at four locations (Rangpur, Dinajpur, Gazipur and Jessore) during the year 2009-10. Randomized complete block design was used as experimental design with 4 (four) replications. The unit plot size was 10m × 3.6 m (4 rows). The plant spacing was 0.90m between the lines and 0.45m between the plants. Among the treatments significant difference was found in number of vegetative branches per plant, secondary fruiting branches per plant, days to first flowering and other traits showed statistically similar results. The highest amount of seed cotton and lint was produced by JA/2000/526 which was (2109kg ha ^-1) and 711kg/ ha, respectively .

Location: Cotton Research Farms of Cotton Development Board located at Rangpur, Dinajpur, Gazipur and Jessore

Start Date: 00-07-2009

End Date: 00-02-2010

Program Area: Variety and Species

Commodity: Cotton

Objectives:

To observe the yield potentiality and response to different environment and to select the best line.

Methodology:

The Experiments was conducted at four Cotton Research Farms of Cotton Development Board located at Rangpur, Dinajpur, Gazipur and Jessore during the year 2009-10. Five advanced lines encoded BC-051, BC-0165, BC- 0406 JA/2000/526, and BC- 0342 , were included in this experiment. CB-9 and CB-10 was taken as local control. The experiment covered the time from last week of July 2009 to last week of February 2010. The trial was set within 24 July to 7 August -2009 at different locations. Randomized complete block design with four replications was followed. The unit plot size was 10m × 3.6 m (4 rows). The plant spacing was 0.90m between the lines and 0.45m between the plants. Two or three water soaked and Asataf treated seeds were sown hill^-1 during planting time, but after final thinning one seedlings hill^-1 was allowed to grow. Green manuring (Sunhemp) and decomposed cow dung at the rate of 3000 kg ha^-1 were applied before final land preparation. All chemical fertilizers except three fourth of urea and one third of MOP were applied in the sowing time. The rest amount of urea was applied in three equal installments as side dressing at the time of 3rd , 6th and 9th week after sowing date. At the last side dressing of N, 37.5 kg ha^-1 K were also applied. At drought condition irrigation was given in all locations. Data on vegetative branches plant^-1, main stem node number of first fruiting branch, primary fruiting branches plant^-1 , secondary fruiting branches plant^-1, days to first flowering, days to first boll split, plant height at harvest, number of bolls plant^-1 , single boll weight, yield plot^-1 were recorded. In all cases data were collected from 10 randomized selected plants of middle two rows of each plot to avoid boarder effect. Mean data was used for statistical analysis.

Achievement/Findings:

Aadvanced lines JA/2000/526 produced the highest amount of seed cotton. It also gave the highest amount of lint and produced good quality lint, so JA/2000/526 may be forward to candidate variety trial and the rest treatments need further investigation through advanced yield trials.
