Abstract:
This experiment is evaluation of genotype effect value and different types of potato mini-tubers planting bed composition on quantitative properties of potato include total number of mini-tubers, number of mini-tubers in standard size, mini-tubers dry matter and root dry matter. This research is a three-factor factorial experiment on based of randomized completely design in four replication at Seed and Plant Certification and Registration Institute (SPCRI) located In Iran in agricultural year of 2010-2011. The first factor (genotype) in three levels (Agria, Sante and Satina), the second factor (planting bed) in six levels (peat moss+sand (1:1by volume) , coco peat+perlite+sand (1:1:1 by volume) , peat moss+perlite (3:1 by volume) , peat moss+sand+perlite (1:1:1 by volume), coco peat+perlite+peat moss (1:1:1 by volume) , coco peat+sand (3:1 by volume)) and the third factor (pot size) in two levels (1.5-liter and 3-liter). results indicated that different genotype and different planting beds lead to create significant differences (p≤0.01) in all of the four evaluated traits in this research. Existence of these differences verity in the pot size factor, but with this odds that pot size in mini-tuber dry matter trait couldn’t result significantly differences. On base of these experiment results it shall be stated that Sante cultivar due to having most optimum values in these experiment traits is known as most suitable genotype rather than the other genotypes. Also peat moss+sand (1:1by volume) planting bed had better properties than the other planting beds.must be noticed that bigger pot size leads to more total mini-tuber, more mini-tuber dry matter, and more root dry matter but produce less number of mini-tuber in standard size.
