Abstract/ Executive Summary:

Five exotic varieties namely El Mondeo, Kufri Pukhraj, Metro, Vivaldi and Volumia along with check varieties BARl Alu-7 (Diamant), BARl Alu-8 (Cardinal) and BARl Alu-28 (Lady Rosetta) were evaluated at six different agro ecological environments/locations during 2013-14 cropping season in RYT. Combined analysis was done to observe the genotype location interaction. Expression of different characters of potato was influenced by different environment factors. All the tested exotic varieties yielded higher than the all check varieties in both 65 and 90 DAP. Satisfactory dry matter percent was also in all tested exotic varieties. So, considering the yield in farmers' field trial, post- harvest, processing, disease and insect data exotic variety El Mondeo, Kufri Pukhraj, Metro, Vivaldi and Volumia were recommended for release for commercial varieties .

Keywords: Exotic varieties, Yield, Potato

Location: Joydebpur, Munshigonj, Bogra, Jamalpur, Jessore and Debigonj.

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Potato

Objectives:

To evaluate the varieties before release as a commercial variety.

Methodology:

Five exotic potato varieties namely EI Mondo, Kufri Pokhraj, Metro, Vivaldi and Volumia selected from last three consecutive years (TCRC, 20011-2013) along with check varieties BARI Alu-7 (Diamant), BARI Alu-8 (Cardinal) and BARl Alu-28 (Lady Rosetta) were evaluated at Joydebpur, Munshigonj, Bogra, Jamalpur, Jessore and Debigonj during 2013-14 cropping season in RCB design with three replications in each location. The unit plot size was 3m x 3m. Whole tubers (BSPC, Debigonj source) were planted with a spacing of 60 cm x 25 cm. Planting was done during November 19 to 28, 2013. Fertilizers were applied @ 325-220-250-120 kg/ha of urea, TSP, MP and gypsum respectively. Necessary intercultural operations were done as per TCRC recommendation. The crop was visited by the Regional Technical Committee of NSB (National Seed Board) two times and harvested at 65 DAP (Days After Planting) one/two line per plot and rest at 90 DAP in presence of them. Data on yield, yield contributing characters and tuber grading were taken and combined analysis was done over location and their means were compared by DMRT by using computer based statistical software MSTATC. Average mean of tuber grading percent by number and weight was computed over six locations.

Achievement/Findings:

Results of the present study clearly indicated five exotic potato varieties namely El Mondeo, Kufri Pukhraj, Metro, Vivaldi and Volumia produced the higher yield than check varieties in both 65 and 90 DAP. Moreover, satisfactory dry matter was produced by all the exotic varieties. So, the five exotic varieties could be advanced to release as variety considering the result of PVS, disease, insect, post- harvest and processing.
