ARAMENDIZ-TATIS, Hermes; CARDONA-AYALA, Carlos  and  CORREA-ALVAREZ, Ender. GENETIC PARAMETERS IN EGGPLANT (Solanum melongena L.). rev.udcaactual.divulg.cient. [online]. 2014, vol.17, n.2, pp.361-369. ISSN 0123-4226.

Genetic parameters of interest were estimated for fruit yield and other agronomic characters in eggplant. Analysis of variance revealed the existence of genetic variability in all evaluated characters, except for the number of fruits per plant in the studied lines. The genetic variation coefficient ranged from 7.33% for fruit length and 39.47% for the number of seeds per fruit, the variability indices showed a range between 1.23 for firmness and 2.70 for seed number per fruit. The broad-sense heritability ranged from 60.45% for fruit firmness and 87.97% for the number of seeds per fruit. The greatest genetic advance was achieved for fruit firmness and number of branches per plant, with 32.73% and 34.89%, respectively, reflecting the effectiveness of selection on genetic variability in the population studied.

Keywords : Phenotypic variance; genetic variance; heritability; variation index.
