Genetic parametres and performance for yield and its components for some varieties of eggplant under Mosul city environment

Abstract

This study was conducted in the vegetable research field, college of agriculture and forestry, horticulture and landscape design, Mosul Univ., using RCBD design with three replicates,  during the spring growing season (2018) for evaluation of the performance yield and its components in nine eggplant varieties under Mosul city environment Iraq at 36°2′ longitude and 43°7′ latitude. The data was recorded for the traits: plant height (cm), number of branches in each one of the plants, fruit weight (gm), number of fruits in each one of the plants, yield in each one of the plants (kg), length and diameter of fruit (cm), and total yield of fruits (ton /ha.). The results indicated that the nine varieties were different in most traits, the Alton kubry and karamleshy c.v gave high results in plant length(116.433, 130.00) respectively, the Mosal local c.v. and White beauty c.v were superior in the length of fruit than other genotypes under the study they gave (15.033 and 15.433 cm) respectively, whereas the number of the fruits per plant has been recorded in White long and Mosely c.v. (18.367 and 19.367 ) respectably.  The genotype Alton kubry gave a high value in fruit weight (287.20gm). The phenotypic and genotypic variations (σ²p and  σ²g) have been higher in the height of the plant, weight of the fruit, the number of fruits in each one of the plants, yield in each plant, and total yield of fruit for each unit area, the heritability (H²_b._s.) was more than 65% for most traits under the study for nine c.v of eggplant. Also, the genetic advance was higher in most traits.
