Abstract/ Executive Summary:

The study was conducted at the farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during March 1995 to March 1996. The results of the study indicated the existence of a wide genetic variability among the lines. Pseudostem height of nine' plantain lines varied from 2.05 m to 2.80 m . The longest pseudostem was recorded at shooting in Jamalpur-2 (2.80 m) and the shortest in Borobhagnia (2.05 m). Base girth of pseudostem ranged from 51.84 cm in Borobhagnia to 65.48 cm in Jamalpur-2. The base girth of Dhak a-l , Jamalpur-l and Anazi did not differ significantly with Jamalpur-2 . Total number of leaves per plant was similar in height out of nine lines. Number of green leaves at shooting varied from 10.02 to 11.17. Total number of leaves per plant was maximum in Kapasia while number of green leaves at shooting was maximum in Jamalpur-l. Anazi took the longest duration (379.33 days) which was closely followed by Dhalpoush (362.33) and Jarnalpur- I (362.35) Kapasia took minimum duration (316.33) to reach harvestable maturity. Finger size was found to vary from 18.14 to 20.80 cm in length and 4.14 to 4.92 cm in diameter. The fingers of Anazi were the largest in size . The lines were different in providing percent edible portion which ranks from 48.840/0 in Jamalpur-2 to 70.08% in Anazi. Weight of bunch varied from 7.23 kg to 10.88 kg which was highest in Kanthali closely followed by Anazi (l0.72 kg), Hathazari (l0.29 kg) and Kapasia (10.03 kg) including others. Kanthali produced the maximum yield (27 .20 t/ha) which was followed by Anazi (26.80 t/ha), Hathazari (25.72 t/ha), Kapasia (25.07 t/ha), Jamalpur-2 (24.32 t/ha), Borobhagnia (23.72 t/ha), Jamalpur-l (23.32 t/ha) and Dhaka -I (18.07 t/ha). Considering yield and yield components of Kanthali, Anazi, Hathazari and Kapasia, these Iines are highly promising for commercial cultivation in Gazipur area.

Start Date: 00-03-1995

End Date: 00-03-1996

Program Area: Variety and Species

Commodity: Banana

Objectives:

To identify high yielding lines with desirable traits to recommend for profitable commercial cultivation.

Methodology:

The study was conducted at the farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur during March 1995 to March 1996. The experiment was set up in a Randomized Complete Block Design with replications. Nine land races of the crop constituted nine treatments. Rhizomes (average weight 535 ± 50 g) were planted on 20 March 1995 at 2 m x 2 m spacing in a unit plot of 30 m x 18 m size. Thus there were 135 plants per plot. Cowdung, urea, TSP, MP, mustard oil cake and gypsum were applied in the experimental field @ 10 kg, 500 kg, 400 g, 500 g and 200 g per plant, respectively. Entire quantity of cowdung, TSP and gypsum were applied in pits. Urea and MP were applied in five equal installments at 45 days interval starting two months after planting. Mustard. oilcake was applied in two installments three and a half month and five months after planting, respectively. Weeding, desuckering, irrigation,. mulching and propping were done as and when necessary. There was shooting in the middle of December 1995. The fingers at marketable stage were harvested 80-90 days after shooting. Data in respect of plant height, base girth, total number of leaves and number of green leaves were recorded at shooting. Weight of bunch, number of hands, weight. and size of fingers and percent edible portion of fruits were also recorded at harvest. The analysis of variance was done and the means were separated by DMRT for interpretation of the results.
