Preferred Abstract (Original):
Genetic
diversity in 50 snake melon accessions collected from Palestine (West
Bank) was assessed by examining variation in 17 phenotypic characters.
These accessions belonged to four important landraces of Cucumis melo
var. flexuosus: green Baladi (GB), white Baladi (WB), green Sahouri
(GS), and white Sahouri (WS). Principal component analysis (PCA) and a
dendrogram were performed to determine relationships among populations
and to obtain information on the usefulness of those characters for the
definition of cultivars. PCA revealed that secondary fruit skin color,
flesh color, primary fruit skin color, and secondary skin color pattern
were the principal characters to discriminate melon accessions examined
in the present study. According to the scatter diagram and dendrogram,
landraces of Cucumis melo var. flexuosus: GB, WB, GS, and WS formed
different clusters. However, based on Euclidean genetic coefficient
distances, GB and WB had the least degree of relatedness with GS and WS,
indicating distantly related landraces (Baladi and Sahouri). On the
other hand, the highest degree of relatedness was detected between WS on
one hand, and both GS and WB on the other indicating closely related
cultivars. Fruit traits variability among the different snake melon
landraces was evaluated and discussed in this study. This evaluation of
fruit trait variability can assist geneticists and breeders to identify
populations with desirable characteristics for inclusion in cultivars
breeding programs. | Attachment | Size |
