SUPERIORITY OF LOCAL EGGPLANT HYBRIDS FOR QUANTTYTRAWS.
This work was carried out during summer season for two years from 2003-2004 at a private farm located at Orman district, Talka ‘ Oakahlia Governorate l Egypt to produce some local long black eggplant hybrids which show high productivity and high quality to meet the desires of consumer and farmer. On 20 March 2003 half diallel set crosses were made between four parental lines of long black eggplant cultivars namely Se, 39. $13 and 81.5 giving 6F1 crosses. In 2004 the four parents and 6 F1,s were evaluated during the summer season at the same private farm under drip < /p> irrigation system . The obtained results indicated that heterosis over the better parent gave positive values in most crosses for plant height, early yield per plant , number of fruits per plant , total yield per plant and total yield per plot and all F1 hybrids gave negative values of heterosis for number of days to 25% flowering where the negative values indicate that the six crosses were earlier than the better parent to each cross . Concerning general combining ability , it was found that Sta was the best combiner for number of branches , number ofdays to 25% flowering (earliness) _ early yield per plant , number of fruits per plant. total yield per plant and total yield per plot. followed by 8.5 parental line . Concerning specific combining ability _ 85x8“; hybrids was found to be the best cross for number of fruits per plant , total yield per plant and total yield per plot , followed by 85x81; , 85x89 and S'gxsre hybrids which gave positive values of sca for total yield per plot. Additive gene effects appeared to be more Important than non additive gene effects as reflected on the high estimated of goat variances relative to those of sea variances for each of number of branches per plant and number of days to 25% of flowering . While it was found that non additive gene effects appeared to play important roles than additive effects for plant height , early yield per plant , number of frurts per plant , fruit weight . total yield per plant , frutt length . fruit diameter , fruit shape index and total yield per plot. Positive correlation was found between total yield per plot and each of plant height, number of branches per plant , early yield per plant,number of fruits per plant, fruit weight , total yield per plant ‘ fruit length and fruit diameter On the other hand , number of days to 25% flowering and fruit shape index reflected negative correlations. Finally , it can be concluded that the hybrids SaxSre . SaxSn , 85x89 and 8961.3 had a good specific combination for total yield per plot and fruit quality of local long black eggplant hybrids.
