Abstract/ Executive Summary:

The trial was conducted at the experimental field of Vegetable Division, HRC, BARI, Joydebpur in winter 2017. Eight S₂ and S₃generations of sweet pepper lines were advanced to S₄to S₅generations respectively to develop variable sweet pepper inbred lines for the development of good hybrid varieties. Variations were found among the lines for the characters studied. Duration of fruit harvest (DFtH) varied from 59-67 days, fruit length 10.2-12.7 cm, marketable fruits per plant (MFPP) 9-17, average fruit weight (Av.FWt.) 45.8-69.3g, yield per plant 0.52-1.17 kg and mite infestation (%FtFlyInfest) 0.0-7.2% and fruit diameter (Fruit dia) 5.7-7.1 cm. Best individuals from every line of sweet pepper were selected and selfed. Seeds of S₂ to S₃ progenies of sweet pepper lines were stored for advancing S₄ to S₅progenies in the next year.

Keywords: Sweet pepper, Hybrid varieties, Harvest, Generation.

Location: Vegetable Division, HRC, BARI, Joydebpur, Gazipur Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Variety and Species

Commodity: Sweet Pepper

Objectives:

To develop variable sweet pepper inbred lines for the development of hybrid varieties.

Methodology:

The study consisted of eight lines of sweet pepper of S₂ (CA005-1-3, CA007-2-5 and CA010-4-2) to S₃ (CA011-3-3, CA012-2-3, CA014-3-4, CA016-5-2 and CA020-2-3) generations of indigenous origin. The trial was conducted at the experimental field of Vegetable Division, HRC, BARI, Joydebpur. Seeds of each line were sown in the seed bed on 02 November, 2017 and seedlings were transplanted in the main field on 10 December. The unit plot size was 3.0 × 1.0 m accommodating 16 plants in each plot having 50 cm × 40 cm plant spacing. Standardization of the manure and fertilizers for sweet pepper has still not been done under Bangladesh condition so far it was reviewed. However, Edison (1995) recommended manure and fertilizers doses for sweet pepper and till today, the Spices Research Centre of the Bangladesh Agricultural Research Institute (BARI) has been following that in sweet pepper. Based on this crop was fertilized with cowdung, urea, TSP, MoP, gypsum and ZnO @ 10 t/ha, 217, 333, 200, 111 and 5 kg/ha, respectively. Half of the quantity of cowdung was applied during final land preparation. The remaining half of cowdung, the entire quantity of TSP, ZnO, gypsum and one third each of urea and MoP were applied during pit preparation. The rest of urea and MoP were applied in two equal splits, 25 and 50 days after transplanting of seedlings in the field. Irrigation, pruning, mulching, weeding and other intercultural operations were done as and when necessary. Standard agronomic practices were followed as and when necessary. Selfing and selection process was followed on the basis of crop improvement procedure. Selected plants were selfed. Selfing was done at anthesis at different days. Seeds of selfed fruits were stored for advancing next generation. It was a non replicated trial. Measured traits include duration of fruit harvest, fruit length, fruit diameter, marketable fruits per plant, average fruit weight and yield per plant.
