Abstract/ Executive Summary:

The performance of elite color capsicum genotypes for growth and yield parameters were evaluated under (AEZ-28: Modhupur Tract) at Narsingdi region which is nearly the center of Bangladesh especially in the Regional Horticulture Research Station of Bangladesh Agricultural Research Institute (BARI) at Shibpur in Narsingdi during rabi season of 2015 to 2016. Six colored capsicum genotypes viz., 'California Wonder' 'CA 0025 F1', 'Yellow Square', 'Red Master F1', 'Yolo Wonder' and variety 'BARI Mistimorich-1' as a check. Under the agro climatic condition at AEZ- 28 most of genotypes performed well. Considering the plant growth characteristics and phenology, such as plant height, early flowering dates and the longest harvest duration, line 'CA 0025 F1' was found the best in this region. In case of yield contributing characteristics, the maximum (16.67) fruits plant^-1 was recorded from the line 'CA 0025 F1' and the minimum (8.84) was recorded from the line 'Yellow Square'. However, individual fruit weight was found the highest in 'Red Master F1' (148.71 g) whereas, the lowest was found from line 'CA 0025 F1' (43.39 g). In prospect of yield, 'Red Master F1' produced 22.05 t ha^-1, followed by check variety 'BARI Mistimorich-1' (19.64 t ha^-1), followed by California Wonder (17.90 t ha^-1). The maximum seeds fruit^-1 and thousand seed weight was found in line 'CA 0025 F1' (122.2 and 5.17 g), followed by 'Red Master F1' and 'California Wonder'.

End Date: 00-04-2016

Program Area: Variety and Species

Commodity: Capsicum

Objectives:

The present study was undertaken with a view to develop improved color capsicum variety(s) and its adaptability at Narsingdi region (AEZ-28; Modhupur Tract) of Bangladesh.

Methodology:

The experiment was carried out under AEZ-28 (Modhupur Tract) at Narsingdi region (23? 55′ 22″ N and 90? 43′ 03″ E) of Bangladesh especially in the Regional Horticulture Research Station (RHRS), Bangladesh Agricultural Research Institute (BARI), Shibpur, Narsingdi during winter (Rabi) season of October 2015 to April 2016. The land type was sandy loam soil and analytical data of soil sample was present. Experimental design - Five lines of color capsicum viz., California Wonder (T₁), CA 0025 F₁ (T₂), Yellow Square (T₃), Red Master F₁ (T₄), Yolo Wonder (T₅) with a variety 'BARI Mistimorich-1' were used as experimental materials. The seeds were sown on October 12, 2015 in the seed bed. Fifteen days after sowing when the seedlings attained 2-3 leaf stages, they were transferred to the polybags filled with potting media. Thirty five days old seedlings were transplanted in the experimental plots. The experiment was laid out at Randomized Complete Block Design (RCBD) with three replications. The unit plot size was 4.2 m × 1.0 m and plants spacing was 60 cm × 50 cm. The number of plants in a unit plot was fourteen. Management practices - Cowdung, Urea, TSP, MoP, Gypsum and ZnO at the rate of 10 ton, 217 kg, 330 kg, 110 kg, 6.5 kg, and 5 kg ha^-1, respectively were applied. Half of the quantity of cowdung was applied during final land preparation. The remaining cowdung, entire quantity of TSP, ZnO, Gypsum and one third of urea and MoP were applied during pit preparation. The rest of urea and MoP were applied in two equal installments at 25 and 50 days after transplanting as top dressing. The intercultural operations such as weeding, irrigation etc. were done as and when needed. Data collection and statistical analysis - Data were collected on different parameters like plant height at last harvest (cm), days to 50% flowering, harvest duration, fruit length (cm), fruit diameter (cm), peduncle length (cm), peduncle breadth (cm), single fruit weight (g), no. of fruits/plant, wt. of fruits/plant (g), average seed per fruit, 1000 seed weight (g), yield (t ha^-1) were recorded. Five plants were selected to record the yield and yield contributing characters. Mean data were analyzed statistically by analysis of variance (ANOVA) techniques using Statistical Tool for Agricultural Research (STAR), version 2.0.1. Analysis and significant means were separated at 5% level of significance.

Achievement/Findings:

The performance of the six sweet pepper lines was accomplished under the agro-climatic and adapted conditions at center region of Bangladesh especially in the Regional Horticulture Research Station, BARI, Narsingdi and the ultimate goal of the field performance was to estimate the yield potentialities and growing condition of the lines. In aspect of growth condition, early flowering dates, fruit setting, the longest harvest duration and the highest fruit per plant CA 0025 F₁ showed as the most adaptable line in this agro-climatic condition under AEZ- 28 of Bangladesh. In aspect of yield, the highest yield resulted due to some yield contributing characters was found in Red Master F₁, BARI Mistimorich-1 and California Wonder. Considering yield and overall performance of the lines/varieties, Red Master F₁, BARI Mistimorich-1 and California Wonder were found superior to other lines/varieties.
