SALAZAR-GARCIA, Samuel; MEDINA-CARRILLO, Raquel Enedina  and  ALVAREZ-BRAVO, Arturo. Initial evaluation of some aspects of quality fruit avocado ‘Hass’ produced in three regions of Mexico. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.2, pp.277-289. ISSN 2007-0934.

Mexico is the largest producer of avocado 'Hass' in the world and the largest area is located in western Mexico. The price of the fruit of 'Hass' varies according to their place of origin on the grounds that it is due to differences in skin roughness, seed size and texture and pulp quality. There is a lack of information on these alleged differences. The objective of this research was to determine some physical, chemical and organoleptic fruit of 'Hass' producing regions in the states of Michoacan, Jalisco and Nayarit features. The fruits analyzed were originated by normal flowering (winter 2012) and harvested in October 2013 with a content of dry matter in the pulp> 22%. They assessed physical and chemical characteristics in two phases: 1) harvest; and 2) consumption maturity reached at room temperature (21 ± 1 °C). Organoleptic quality was evaluated in mature consumer. The fruits of Nayarit roughness and had the highest weight ratio of skin, Jalisco most weight ratio of the pulp and Michoacan the higher oil content. Sensory evaluation of the fruit showed no difference between the producing regions. The average air temperature was the variable that most correlated with some physical characteristics of the fruit. The differences found for some physical and chemical fruit of 'Hass' for each producer region features not affect its organoleptic quality.
