Abstract:
The study was carried out, in the Central Highlands Region, Dhamar Governorate – Republic of Yemen in nine different locations during the summer season (July) 2020 AD. The study was concentrated in three districts, which are Mayfa’a Ans, Otma and Al-Hadda. In each district, three locations were chosen for the purpose of evaluating and studying the phenotypic and productive characteristics of tree varieties of pea (1 local and two improved Yahsob and Amran). Each cultivar was planted with an area of 150 m2 in each site and was relied on 30 descriptive and quantitative traits. The results showed that the cultivars were divided into two groups, the first for the local cultivars (Landraces), the second group included the two improved cultivars Yahsob and Amran, The results of the cluster analysis indicate that the improved varieties differed from the local variety in many characteristics, and the degree of kinship reached only 40%, which indicates the presence of genetic divergence between them, while the degree of kinship between the variety Yahsob and Amran reached 93%, which indicates the presence of genetic closeness between them, and therefore it is possible to rely on the phenotypic characteristics to distinguish between the varieties, the study confirms the importance of expanding it by increasing the number of varieties in addition to the molecular study.
Key words: characteristics, traits, phenotypic, productive, cluster analysis and genetic kinship.
