Abstract/ Executive Summary:

A study was conducted to evaluate two grape germplasm VV Kha-001 and VV Kha-002 at the Hill Agricultural Research Station, Khagrachari during the period from February 2013 to July, 2014. The plant growth was excellent for both the germplasm. Regardless of germplasm the full blooming period was February, and fruits of VV Kha-001 were harvested at early July and VV Kha-002 at mid July. The Maximum number of fruits per cluster (28) was recorded from VV Kha-001 while minimum (25) in VV Kha-001. The highest number of clusters per plant (13) was obtained from VV Kha-002 in against the lowest (9) in VV Kha-001. Individual fruit weight was found maximum (3.60g) in VV Kha-002, while minimum (2.82 g) in VV Kha-001. The highest seeds per fruit (2.4) was recorded in VV Kha-002 and the lowest (2.2) in VV Kha-001. Total Soluble Solids (TSS) was noted the highest (18%) in VV Kha-001 and the lowest (16%) in VV Kha-002. The highest yield per plant was obtained from VV Kha-002 (1.17kg) and the lowest in VV Kha-001 (0.71kg). Irrespective of germplasm long cylindrical shaped fruit having light green skin with pleasant flovour sweet in taste.

Start Date: 00-02-2013

End Date: 00-07-2014

Program Area: Variety and Species

Commodity: Grape

Objectives:

To study the performance of grape (Vitis vinifera) germplasm in Bangladesh

Evaluate, characterized and documented the pomological characteristics of grape

To select a suitable grape germplasm for release as a variety.

Methodology:

The study was carried out at the Hill Agricultural Research Station, Khagrachari during February 2013 to July, 2014. Two germplasm of grape viz. VV Kha-001 and VV Kha-002 were included in this study. The 5 cuttings the germplasm were planting in the field maintain 2 x 2 m plant spacing during September 2012 and July 2011, respectively. The usage of organic manure has assumed high importance for grape. A standard dose of 500:500:1000 kg of N, P₂O₅ and K₂O per hectare at the end of April and September. The annual dose is fixed based on the petiole analysis carried out at 45 days after spur pruning. While 40 percent of the annual dose is given through organic sources, 60 percent is given as inorganic fertilizer. Calcium ammonium nitrate is usually not used. Sulphate of potash is the only source of potash used instead of muriate of potash, particularly in heavy clay soils. Recently application of soluble fertilizers through drip irrigation (fertigation) was picking up. 40 percent of N, 50 percent of P₂O₅ and 33 percent of K₂O of the annual dose is given during the growth season and the rest in the fruiting season. Weeding and irrigation were done as and when necessary. Necessary actions were taken against other pests and diseases as and when needed. Data on base girth (cm), growth condition of plants, time of blooming, time of harvesting, number of bunch/plant, number of fruit/bunch, single fruit weight (g), fruit length (cm), fruit breadth (cm), number of seed/fruit, 10 seed weight (g), seed length (cm), seed breadth (cm), skin weight (g), yield/plant (kg), TSS (%), edible portion (%), fruit shape, fruit surface, skin color, flovour, attrctiveness and organoleptic taste were recorded as per IPGRI descriptors. The data were analyzed through simple statistics for interpretation the results properly.

Budget: 25000/-

Total Budget (Tk.) : 25000/-

Achievement/Findings:

The overall growth condition of both the germplasm was found satisfactory. Considering yield, quality and sweetness VV Kha-001 were found most promising at hilly region and might be recommended for release as a variety.
