Abstract/ Executive Summary:

This experiment was conducted from March 2017 to July 2017 in the experimental field of ARS, BARI, Cumilla. A total of 13 (thirteen) germplasm of okra were collected from different upazillas of Cumilla district to develop a new okra variety with high yield and tolerance to YVMV. The experiment was set in RCBD design with three replications. Results revealed that both AE Com-001 and AE Com-004 produced the highest yield (5.6 t/ha) and the minimum yield was produced by AE Com-013 (0.25 t/ha). Among the thirteen germplasms, AE Com-001 (30%) showed minimum YVMV infestation while maximum infestation was recorded on AE Com-013 (95%) compared to others.

Location: Agriculture Research Station (ARS), Cumilla, Bangladesh

Start Date: 00-00-2017

End Date: 00-05-2018

Program Area: Variety and Species

Commodity: Okra

Objectives:

To develop new high yielding okra variety.

Methodology:

This experiment was conducted at the experimental field of Agriculture Research Station (ARS), Cumilla during the Kharif season of 2017. The thirteen genotypes, viz. AE Com-001, AE Com-002, AE Com-003, AE Com-004, AE Com-005, AE Com-006, AE Com-007, AE Com-008, AE Com-009, AE Com-010, AE Com-011, AE Com-012 and AE Com-013 were collected from different areas of Cumilla. The lines were placed in a randomized complete design with three (3) replications. The seeds were sown on 30 March 2017. The unit plot size was 4.0 m x 1.0 m and the plants were spaced at 60 cm x 40 cm. Cow- dung, urea, TSP, and MOP at the rate of 15 t, 160, 150, and 150 kg per hectare, respectively were applied. The entire amount of Cow dung and TSP and two-third of MOP were applied at the time of final land preparation. The remaining MOP was applied after 30 days of seed sowing. Urea was applied in three equal installments at 30, 45, and 60 days after sowing. Other necessary intercultural operations were done as and when necessary. Data on yield and yield attributes were recorded.

Achievement/Findings:

Yield contributing characters of okra germplasm were varied significantly. The result revealed that fruit length and fruit breadth differed significantly among the germplasm. The longest fruit was observed in AE Com-010 (11.73 cm) and the shortest was observed in AE Com-005 (7.41 cm). The widest fruit was achieved from AE Com-007 (1.62 cm) and the narrowest fruit was achieved from AE Com-013 (1.31 cm). The number of fruit per plant was also statistically varied among the okra germplasms. Maximum fruit per plant was produced by AE Com-005 (25.33) followed by AE Com-002 (25) and minimum was produced by AE Com-007 (3) Highest fruit yield per plant was produced by AE Com-004 (428.33 g) followed by AE Com-006 (411.93 g) and lowest was produced by AE Com-007 (49.68 g). Fruit yield (ton per hectare) also varied significantly and it ranged from 0.25 to 5.6. Both AE Com-001 and AE Com-004 produced the highest yield (5.6 t/ha) followed by AE Com-002 (5.2 t/ha) and the minimum was produced by AE Com-013 (0.25 t/ha). Among the thirteen germplasm, all showed virus produced susceptibility, but AE Com-001 showed minimum virus infestation compared to others. The germplasm AE Com-001 and AE Com-004 produced the highest yield and AE Com-001 showed minimum YVMV infestation.
