Evaluation of changes of protein percentage, lysine and methionine amino acids in potato genotypes and cultivars

It is important to select high yielding and nutritious varieties for potato cultivation. Therefore, an experiment was conducted as randomized complete blocks design (RCBD), with three replications with 15 potato cultivars and 5 potato genotypes (Sprite, Savalan, Satina, Banba, Buren, Sinja, Ausonia, Kosima, Kondor, Fiannee, Granula, Agria, Agta, Miriam, Morene, 397082-2. 397097-2, 396124, 39704515, 396156-5) in Research Farm of University of Mohaghegh Ardabili in 2011. Results showed that plant height, number of tubers, tuber yield, protein yield and yields of lysine and methionine amino acids of genotypes and cultivars were significant at 1% probability level. Savalan cultivar and 396124 and 39704515 genotypes produced highest tubers yield. Protein yield in cultivars, Cosima, Fiannee, Moran and 397082-2 genotype, and the yield of Lysine amino acid in 397082-2 genotype and the yield of Methionine amino acid in Cosima cultivar were the highest. Cluster analysis of genotypes and cultivars in regard to protein, tuber, Lysine and Methionine amino acids yield classified them into three groups. In this classification, most cultivars and genotypes have a long growth period, also had higher average quantitative and qualitative characteristics optimal. Overall Savalan, Cosima, Fiannee, Moran, Ausonia cultivars and 397097-2 and 39704515 genotypes were selected as superior varieties for production in this area and similar climate conditions.
