: The present study aimed to improve the body weight in the Alexandria chickens by selection for the skeletal traits of the high breast width, breast length and leg length at eight weeks of age. 2500 birds at a day of hatch were obtained from 5 consecutive hatching weekly hatches were taken for one generation. The results of this study showed that the overall means for body weight at four weeks (BW 4 ), body weight at eight weeks (BW 8 ) and body weight at twelve weeks (BW 12 ) were (204.699 and 190.02 g), (718.559 and 610.20 g) and (1289.99 and 1049.002 g) for males and females, respectively. These results showed that the differences among line were highly significant (P ≤ 0.01) in selected line than control line in BW 8 and BW 12 . Also, the overall means of shank length in eight weeks of age (SL 8 ), breast length in eight weeks of age (BRL 8 ) and breast width in eight weeks of age (BRW 8 ) were (6.81 and 6.38 cm), (11.85 and 11.23 cm) and (11.24 and 10.78 cm) for males and females, respectively. The selection for the skeletal traits in Alexandria chickens in eight weeks of age showed that

Two tested acetone algae extracts of Spirulina platensis and Chlorella vulgaris in the present study significantly decreased radial growth (colony diameter) of the potato dry rot fungus, Fusarium sambucinum (isolate, F.s. 2), grown on PDA amended with the tested algae extracts,7days after inoculation and incubation at 25 o C. This effect increased with increasing the concentration where 160 mg/ml of any of the tested extracts completely (100%) inhibited the fungus growth. Meanwhile, treatments with the two tested acetone algae extracts (as dipping or coating in gelatinous substance) significantly decreased dry rot disease severity on the inoculated potato with F.s. 2 under cold storage conditions (7±2°C) compared to the untreated inoculated control and the effect increased with increasing the concentration from 160mg/ml to 200 mg/ml. Also, coating tubers with the tested algae extracts was even more effective to decrease dry rot disease severity during storage. Spirulina extract treatments consistently decreased the developed dry rot severity compared to Chlorella treatments. This effect of algae extracts may be explained in view that the algae extracts treatments were accompanied with significant
