Abstract:
The present experiment was carried out for the evaluation of processing type of potato (Solanum tuberosum L.) for yield and quality attributes among 12 potato genotypes with respect to morphological and physiological traits and the association of different characters with process grade tuber yield. The genotype AICRP P-24 (MP/6-39) (74.70 cm) recorded the highest plant height. AICRP P-58 (4.40) recorded the maximum shoots/plant while Kufri Frysona (394000/ha) recorded the maximum numbers of Process grade tuber. Genotype Kufri Frysona (17.2 t/ha) estimated the maximum process grade tuber yield and AICRP P-25 (HT/7-620) (478) recorded the maximum tuber yield. Genotype AICRP P-25 (HT/7-620) (20.71 t/ha) recorded the maximum total tuber yield beside the quantitative analysis, Kufri Chipsona-3 (21.46 mg/100g) recorded maximum ascorbic acid while the maximum starch content was found in the Atlantic (16.41%),the genotype AICRP P-60 (Sagitta) (1.122) recorded maximum specific gravity, AICRP P-25 (HT/7-620) (132mg/100g) having the maximum reducing sugar, genotype Kufri Chipsona 1 (17.54 mg/kg) recorded maximum Zinc content in tuber, The genotype AICRP P-58 (455.5 mg/100g) recorded maximum Potassium content in tuber, genotype AICRP P-58 (63.47 mg/100g) recorded maximum Potassium content in tuber, Genotype Kufri Frysona (22.13%) recorded the maximum Dry matter %. Perusal of the data from the experiment with 12 genotypes it was found that the genotype AICRP P-25 (HT/7-620), Kufri Frysona and AICRP P-58 were identified as best genotypes for yield and yield attributing traits and also for processing.
