Evaluation of Different Pear Cultivars in Northwest Mexico

Pear production in Mexico is low; there are about 4500 ha. One of the main problems in this tree fruit is the unknown number of new varieties for each area. The objective of this study was to evaluate 23 common pear cultivars and seven Asian pears. The experiment was carried out at the Experimental Station “El Tasicuri” of Magdalena, Sonora, Mexico. The trees were planted in 1990 on Pyrus calleryana rootstock. The main results were that common pears were not adapted to the area because of the lack of cold weather; however, `Bartlett' was the only cultivar that was adapted. Asian pears showed good adaption into the region (`Shinseiki', `Kikusui', `Hosoui', `Twenty Century', and `Ya-Li'). The ripening date of these cultivars were from the 7 and 20 of Aug. and the weight of the fruit was 146 and 198 g/fruit. There were no pests or diseases in any of the Asian cultivars.
