Abstract
This study was carried out at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shibin El-Kom during three summer seasons. The cultivar Super Beef Steak and the line Bl-15 were used as parents to produce the required populations, i.e., F1, F2 and Bcp < sub>1 and Bcp < sub>2. The six populations were evaluated for number of days to the first ripe fruit, average fruit weight, total soluble solids and ascorbic acid content, as well as, resistance to the root knot nematode, Meloidogyne incognita. A randomized complete blocks design was used. Data were recorded on an individual plant for each population. Regard to the resistance to root knot nematode, the experiment was carried out in pots. Data obtained suggested that the number of days to ripening showed over-dominance for the short period. Total soluble solids and ascorbic acid contents are controlled by additive gene with slight dominance for the low contents. Partial dominance for the small fruit was found. With regard to root knot nematode resistance, the character is controlled by single dominant gene for low number of galls and egg masses. Therefore, developing of tomato cultivars and F1 hybrids for resistance could be achieved by breeding programs.
