Effect of genotype and storage on textural parameters in potato tubers

Potato lines bred by intraspecific hybridization of Solanum tuberosum L. were evaluated on their textural properties in two consecutive years. The plants grown under mountain conditions at 1610 m altitude and harvested the end September. cutting test was performed using a Warner-Bratzler blade texture analyzer (TA) for obtaining maximum force to shear tubers. Textural parameters analysed right after harvesting, 3- 6-month storage ambient (2-8 ºC 70-90% Rh) unheated storehouse. It found out that values all investigated physical decreased during storage. Higher influence duration than genotype recorded dynamic yield force, modulus deformation, deformation work rupture force. Based studied qualities line E 1096 selected as most appropriate long-term because slightest softening tubers homogenous observed correlations indicated may give best information about quality raw potato texture.
