English Abstract

Five PCR based RAPD markers were used in this study to detect genetic variability during the successive growing seasons of 2014.

under the molecular level among the seven squash genotypes (Eskandarani, Coppi, Saja, Beyaz, Zucchino Ginyoveze, Zucchino tondo di piacen za and Zucchino romanesco).The seven varieties were clustered in two main groups; The first group included two cultivars Zucchino tondo di piacen za (p6) and Zucchino romanesco (P7) these Varietys were the best in yield traits, these traits were fruit firmness (F.F.g/cm2); fruit length (F.L./cm); fruit shape index (F.Sh.I.); Fruit diameter (F.D./cm); fruit weight (F.W./g); number of fruits per plant (No.F./P.) ; First picking date (F.P.D.) and Yield plant for (Y.P./g).

While, the second group divided into sub group the first one include the variety Zucchino Ginyoveze (P5) and the other sub group divided into sub sub group the first one include the variety Coppi (P2) and the other include the varieties Eskandarani (P1) , Beyaz (P4) and Saja (P3).

The Varietys P2 and P5 were the best in vegetative traits , the vegetative traits included number of leaves per plant (No.L./P.), chlorophyll (a) and (b) content (mg.g-1.fw), leaf area(L.A./cm2), and plant height(P.H./cm) while P1, P3 and P4 were the best Variety in earliness traits, the earliness studied traits were: number of node for the first female flowering (No.N.F.F.F.), date of the first female flower (D.F.F.F.), date of the first male flower (D.F.M.F.), Number of fruits per plot for the first seven pickings (NF7P/Plot) and weight of fruits for the first seven pickings per plant (WF7P/g).

DNA (RAPD) used to identify the polymorphisms and the relationships between seven genotypes, using five primers, and concluded that information depend on polymorphism using RAPD markers is useful in the assessment of genetic diversity and genetic relationships and could be useful in the breeding programs.
