Genetic diversity of some apple cultivars in the south of Syria based on morphological characters

Abstract

This work was aimed to evaluate genetic diversity among five local and six introduced apple cultivars in the germplasm which located in the South of Syria based on 29 morphological characters of leaf and fruit. The analysis of variance showed significant differences at P < 0.05 for all measured parameters, however the mean values of Limb length and width, fruit weight, length, and width indicated to a wide range of diversity between local and introduced cultivars, that the introduced cultivars have mostly the highest mean value while the local cultivars have the lowest mean values, that clearly found in the local apple cultivar Ksairi (K) which revealed the lowest mean value of fruit weight (FW), fruit length (FL) and fruit diameter (FD) in the comparison with all studied cultivars. Likewise, principal component analysis (PCA) was used and the first 4 principal components accounted for 76.4% of the total variance, with eigen values 29.2%, 18.8%, 16.9% and 11.5% respectively.

La Diversidad Fenotípica De Manzano en Zacatlán, Puebla, México Es Amplia Y Es Aportada Principalmente Por Características De Fruto

“…Al igual que en otras regiones productoras (González-Horta et al, 2005), en Zacatlán se cultivan árboles de diversas variedades de manzana en huertas pequeñas, con lo que se mantiene la variabilidad entre poblaciones (Damyar et al, 2007) y dentro de ellas; y con la intervención humana se contribuye a la preservación de altos niveles de variación genética (Cornille et al, 2012). Otros autores también han destacado la existencia e importancia de la variación entre variedades en manzano, tanto tradicionales como modernas (Al-Halabi y Muzher, 2015;Farrokhi et al, 2014;Gasi et al, 2010), y la gran variación genética entre y dentro de especies y poblaciones en el género Malus (Gasi et al, 2010;Király et al, 2012;Pérez-Romero et al, 2015).…”

Genetic Diversity Among Old Local Grape Cultivars in South of Syria

“…Ampelographic characters revealed clear morphological discrimination among Syrian old local grape cultivars. However, hierarchical cluster successfully used in genetic diversity studies on different species (Aljane and Ferchichi, 2009;Leaoet al, 2011;Al-Halabi and Muzher, 2015).…”
