Abstract

The study was conducted between 2015 and 2017 on 26 species of Ceratonia siliqua L. at four locations viz. AL Dakaka, Wadi Qandil, Um Al-Toyoor and Al-Baseet, in the north-western region of Latakia governorate, Syria in order to study some chemical properties in the pods and seeds of these species. For total sugars (%), the highest percentage was found in T8 pods (57.7%) followed by the D3 (56.9%). The percentage of protein in the pods ranged between (5- 8.2%) and seeds (25-33%) where T8 recorded the highest values. The highest fat value was found in T8 (1.83%) and D3 (3.75%). The percentage of dry matter in the pods ranged from 12.15% in K3 and 8.16% in T1. These genotypes differed genetically more than because of environmental conditions because the locations of the study were geographically close. The genotypes were distributed within the relationship tree in three groups, the first included 3 genotypes and the third contains 9 genotypes from all the study locations. In contrast, the second group included 4 genotypes from the locations of Um Al-Toyoor, Wadi Qandil and Al-Dakaka.

Abstract

The study was conducted on 27 species of Ceratonia siliqua L. in the years 2014 and 2015 in the northwestern region of Latakia Governorate, which is considered one of the most important natural spread areas in Syria, in order to survay its spread and characterization morphologically to develop a classification key. The carob genotypes were surveyed in four locations (Daqaqa, Wadi Qandil, Um Al-Toyoor, and Al-Basset), and characterized morphologically based on 21 characteristics of the vegetative, syphilis, fruit and seed parts. The variation of the fruit tree was only 56%, and the cultivars were divided into three independent groups, compared to 53%, which were obtained by the analysis of the studied traits which were divided into five groups. The classification keys and morphological identity were obtained for the carob genotypes in the studied area. T8 genotype in Um Al-Toyoor location was superior in its fruits characters compared with the other genotypes.
