Abstract

Two field experiments were carried out in the Department of Horticulture and landscape design - College of Agriculture - Al-Anbar University for the seasons 12-01-2018 and 10-08-2018, five locally pure lines of eggplant were planted in the first season (PH-1001, P2 K-1004, P3-A -1006, P4- N-1007, P5- A-1011) is introduced into a full-fledged full-flip counter to produce 20 reciprocal and reverse hybrids. The seeds of the fathers and their hybrids were sown with the comparative hybrid Barcelona, a Spanish hybrid in the same location in the season 2018-2019 and the RCBD and full three replicates (ie, each plastic house was a duplicate of 3 houses each house area of 150 m 2, to study the evaluation of parents and hybrids and estimate some landmarks Genotype and type of gene action Parents (P1, P2, P4) showed a clear and complex effect for most studied traits, giving an average yield (2684.67, 3245.33 and 2898.67 gm). Plant-1 and Reverse Hybrid (2x1) 4932.00 g-Plant-1w .Edit weight of the fruit, reaching 173.10 gm fruit -1 and 188.11 gm fruit -1 of the above-mentioned hybrids sequentially. The reverse hybrid (2x1) showed the highest hybrid vigor per plant yield 51.97%. The results showed that significant differences were found for the mean GCA, SCA and RCA squares for most studied traits. father 2 showed the best positive effect of the GCA to plant yield and number of fruits. The hybrid crossover (1x2) showed the effect of the SCA in plant yield 1411.5. Non-incremental genetic variance values were higher than the additional variance values for most studied traits, including outcome. The inheritance rate in the broad sense was high in most studied traits, while the narrow inheritance rate was low in most studied traits, which was reflected in the average degree of sovereignty, which was greater than one for most studied traits, so we conclude that the advantage of superior parents in breeding programs to produce superior hybrids A distinctive outcome because it was under the influence of the sovereign act of the gene.
