Study the Genetic Behavior in Some Okra Genotypes

Abstract

During the study that was conducted in the field of vegetable crop research of the Department of Horticulture and landscape design, College of Agriculture and Forestry, University of Mosul in the spring growing season 2018, to study the behaviour of ten genotypes of okra, under the conditions of the city of Mosul, Nineveh Governorate, the study was designed with three replications of the complete random block system.  The genetic analysis of the genetic parameters of thirteen traits was conducted. The results showed that analyzing the sources of variance, the genotypes showed significant differences for all the traits studied under study, and the phenotypic and genotypic variation was high for, plant height, number of fresh fruits per plant, number of seeds per fruit and total seed yield per unit area, And the values ​​of the phenotypic coefficient of variation were higher than the genetic variance factor for all traits. The heritability ratio in the broad sense was higher than 80% for the characteristics of plant height, number of branches per plant, number of fresh fruits per plant, the yield of marketing fruits and the length of fresh fruit, and length Fruit when seeds are extracted, and  number of seeds per fruit. The total seed yield per unit area was positively correlated with the phenotypic and genetically significant characteristics of plant length, fruit length upon seed extraction, and the characteristic of the number of fresh fruits for each plant was positively correlated morphologically and genetically with both the number of seeds / plant and the length of the fruit when extracting the seeds and the length of the fruit Fresh.

Through the analysis of the path, there was a direct positive effect the characteristic of plant height, number of side branches and weight of 100 seeds on the total yield of seeds per unit area.
