Abstract
Fruit culture in Michoacan is typified by the export-orientated crops avocado, mango, guava and lemon.
However, there is a great diversity of plant families and species of tropical and subtropical fruits already cultivated in sparse and mixed small orchards.
Specifically there is a high potential for different Sapotaceae family species with edible fruits.
The objective of this research was to evaluate promising sapotaceae species for fruit production of the Centre-Western Michoacan considering aspects of geographical, ecophysiological, morphological, agronomic, and marketing parameters.
The first stage of this study presents the evaluation of qualitative and quantitative characteristics of 117 trees of Mamey Sapote, Pouteria sapota [(Jacquin) H.E. Moore & Stearn] from 13 different locations within the three most representative production areas.
Clusters analysis of data indicated three distinct Clusters.
Cluster I included 31 genotypes from Nuevo Urecho and Apatzingan municipalities, with strongly branched, upright trees, elliptic and globose fruits with coarse woody skin, and smooth brightly red mesocarp with very sweet taste and low acidity.
Cluster II included 34 genotypes with strongly branched, spreading trees with elliptic, globose and ovate fruits and smooth salmon mesocarp.
Cluster III represented by 52 genotypes mostly from Ziracuaretiro and Apatzingan with low-branched, spreading trees, with small ovate and obovate fruits.
Principal component analysis detected the variables more affecting Cluster differentiation.
Those were fruit weight, fruit length, mesocarp and epicarp weight, seed weight, total soluble solids (TSS) content (°Brix), pH, fruit diameter, tree high, leaf length and width, branch architecture and fructification.
These observations provide the first reported in-depth insights into the genetic diversity of mamey sapote for fruit production in Michoacan.
They furnish the necessary informational framework for future studies in that region.
