Abstract

The study includes Diallel cross of three varieties of Cucumis sativus L. in a way Full diallel cross. An experiment was conducted using 3 males + 6 hybrids + control hybrid. The experiment was carried out in the Horticulture Research Field, College of Agriculture, Baghdad University, and Layout according to split plots arrangement in (R.C.B.D.) with three replication. To study the effect of spraying potassium sulphate at the level of 0, 3000, 6000 mg L-1, on some of the quality and yield males and hybrids cucumber. Results showed out there is a moral effect in fluency of genotypes a male 3 gave the highest number and weight of fruits, the total plant yield and fruit hardest 22.33 fruit, 92.51 gm, 1.86 Kg, 10.47 gm cm-2.
As the a male 2 gave the highest crust diameter 0.56 mm. that is refluxed on hybrid 2*3 gave the highest number of fruits and the total plant yield 28.33 fruit, 2.08 Kg and hybrid 1x3 gave the highest weight of fruits 116.03 gm and hybrid 2*1 gave the highest of crust diameter 0.61 mm, and control hybrid gave the highest hardest of fruit 10.49 gm.cm-2. The interaction a many the male 3 on the level K6000 gave the highest number of fruits, the total plant yield and fruit hardest 29 fruit, 2.38 Kg ,10.47 gm.cm-2 , Also the male 3 on the level K3000 gave the highest weight of fruits, and fruit hardest 143.31gm, 10.47 gm cm-2 and level K6000 the male 1 gave the highest crust diameter 0.59 mm. The level K6000 hybrid 2*3 gave the highest number of fruits and the total plant yield and fruit hardest 36 fruit, 2.88 Kg, 10.50 gm cm-2, the level K6000 hybrid 1*3 gave the highest weight of fruits 161.62 gm, and level K6000 hybrid 2x1 gave the highest crust diameter 0.70 mm.
