To make potato production more sustainable for smallholder farmers, product diversification through processing is critical. On the other hand, the processing sector mandated some stringent standards in order to maintain product quality, hence potato quality evaluations are required for chip processing industries. Specific gravity, starch, reducing sugars, tuber dry matter, and chip color are all important characteristics to consider for processing. This study was designed to find suitable potato varieties with satisfactory attributes for processing chips, in comparison with other processing potato varieties. Keeping this in mind, the study was performed during the winter season of 2019–2020 and 2020–2021 in Bangladesh. Six processing types of potato varieties viz. BARI Alu-25 (Asterix), BARI Alu-28 (Lady Rosetta), BARI Alu-29 (Courage), BARI Alu-68 (Atlantic), BARI Alu-70 (Destiny), and BARI Alu-71 (Dolly) were evaluated for different quality parameters (specific gravity, dry matter, starch content, reducing sugar, chip color, and crispiness). The result of the study showed an ample variation in the studied parameters among the potato varieties. Among the varieties, BARI Alu-28 (Lady Rosetta) and BARI Alu-29 (Courage) were found better for all the quality parameters, such as dry matter, starch, reducing sugar, chip color, and crispiness, and could be recommended for the processing industries.

Aims: The main aim of this study was to find out the suitable variety having the export potentiality. Study Design: The experiment was laid out in a randomized complete block (RCB) design with the two replications in each location. Place of the Study: The study was conducted in ten different agroecological environments across the country, namely Bogura, Jashore, Munshiganj, Gazipur, Patuakhali, Faridpur, Debiganj, Madaripur, Thakurgaon and Rangpur district of Bangladesh during November 2020 to March 2021. Methodology: Sixty-two released potato varieties and exotic materials were used as planting materials for the experiment. Whole seed tubers of 28–40 mm were planted in the last week of November with a spacing of 60 cm between the rows and 20 cm between the plants. The crops were harvested at full maturity during March. Tuber yield was determined by adding the weights of marketable and unmarketable tubers from the net plot area and converting them to tons per hectare. After that, the tubers were graded in different grades and the dry matter of the potato was analyzed. Results: Considering the results, the location Rangpur, Thakurgaon, Debiganj and Bogura are the most suitable place for export variety cultivation in Bangladesh. The potato variety and genotypes 13.7, BARI Alu-12, BARI Alu-61, BARI Alu-68, BARI Alu-73 and Innovator were found promising for export for their yield, tuber size and dry matter content. Conclusion: The variety having good yield, bigger size and high dry matter could be selected for export from Bangladesh and the better-performed regions can be utilized for export quality potato production in Bangladesh.

Thirteen exotic potato varieties along with four checks were evaluated at six agro-ecological locations of Bangladesh for three generations during 2015-16 to 2017-18 in order to identify table purpose and processing quality varieties. Results indicated significant variation among the varieties. Based on the results of the 1st year multi-location trial, seven superior ones were selected for further testing in AYT and RYT in next two years. In the SYT, varieties Farida and 7four7 were the highest yielders. In the AYT, the highest average yield over location was also produced by 7four7 (38.70 t/ha). Varieties Cimega and Memphis also gave comparable yields to that of 7four7 (37.33 and 36.67 t/ha, respectively). Considering the yield of the three generations, the above four varieties were significantly better than the checks. Considering the specific qualities, Farida was found most suitable for table purpose because of its high yield, medium-sized oval and smooth tubers with good eating quality. The variety Taisiya produced tubers with good size and shape, but low in dry matter content; so not suitable for processing. Memphis might be selected for French fry as it produces maximum large sized tubers with good long oval shape. On the other hand, variety Panamera is a high yielder but its plant type was undesirable. On the whole, varieties Cimega, 7four7 and Farida are suitable for table purpose, and Memphis may be selected for French fry under Bangladesh condition. None was found quite suitable for Chips preparation.
