Evaluación de aguacates criollos en Nuevo León, México: región norte

The State of Nuevo Leon, Mexico, is a part of the birthplace of the Mexican breed of avocado (Persea americana Mill. var. drymifolia), where Creole varieties are planted in commercial gardens and backyards, with the outstanding use of the variety Platano Grueso-1 (local variety). This variety is characterized by an early cycle of physiological maturity, allowing production to concentrate into a relatively short period. The objective of this research was to characterize a group of Creole varieties of avocado in the south of Nuevo Leon, using morphological characteristics of the fruit. Twenty nine varieties were used including the variety Platano Grueso-1 (local variety), present in six commercial gardens and a backyard in the municipalities of Aramberri and Zaragoza, Nuevo Leon. Seventeen materials were identified as having morphological characteristics similar to the variety Platano Grueso-1, and they were classified into three groups. The first group is formed by 12 varieties with fruit characteristics similar to those of Platano Grueso-1, with a period of early physiological maturity. The second group is composed of three varieties with characteristics similar to those of Platano Grueso-1, with an intermediate period of physiological maturity. The third group consists of two varieties with similar fruit characteristics to the variety Platano Grueso-1, with a late period of physiological maturity. Results suggest that there is a wide variation in
