MORPHO-PHYSIOLOGICAL CHARACTERIZATION OF TWENTY TWO POTATO GERMPLASM

Abstract

A field research was accomplished at Horticultural farm, Sher-e-Bangla Agricultural University, during the period from October 2014 to April 2015 to study morphophysiological

characterization of twenty two potato germplasm. The experiment was conducted using RCBD with three replications. Potato germplasm from different sources were used in this experiment expressed as G G 3 :Dohajari; G 4 :Shilbilati; G 5 :Jam Alu; G 6 1 :Lal Pakri 1; G :Fauta Pakri; G 7 2 :Lal Pakri 2; :Bogra Guti; G :Ausha; G 9 :Blue white; G 10 :Blue Yellow; G 11 :Burma 1; G 12 :Burma 2; G :Diamont; G 14 :Cardinal; G 15 :Granula; G 16 :Asterix; G 17 :Courage; G 18 :Lady Rosetta; G :Segita; G 20 :Sharpo Mira; G 21 :BARI ALOO 46; G :BARI ALOO 53. Growth and yield attributing parameters were studied in the experiment. Later twenty two potato germplasm have been categorized on the basis of morphological variation using visual observation following UPOV authorized guidelines. The highest percentage of large sized tuber (50%)

found in G 13 and yield ha 22 -1 was maximum (29.9 t/ha) in G . Among twenty two potato germplasm 4 germplasm (G 8 , G 15 , G 17 ,

G ) were found short oval tuber; 6

germplasm (G 2 , G 6 , G 7 , G 10 , G 19 , G 21 22 ) were oval; 5 germplasm (G , G 14 , G 20 ) were long oval; 3 (G 11 , G 12 ,

G 16 ) were long; 2 germplasm (G were very long and 2 germplasm (G 3 , G 18 ) were recorded round shaped tubers. Among twenty two germplasm 13 potato germplasm (G G 20 , G 21

1 , G 2 , G 6 , G 7 , G 9 ,

G 10 , G 11 ,

G ) were found oval to long shaped tubers and their length were close to 90 mm so they can be used in French frying industry while oval germplasm G G 10 , G 15, G 17 G 19 , G 21 and G might be suitable for chips making industry and rest of germplasm G 3 , G 4 , G 5 , G 18 22 can be considered as suitable germplasm in canning and dehydrated product making industry. The findings of the experiment can be considered as a basis for further research on identifying potential potato germplasm for industrial use.
