الارتباطات الوراثية و المظهرية و تحليل معامل المسار للآباء و هجن الجيل الأول في الباقلاء (.Vicia faba L)‎

Abstract EN

An experiment was conducted by using sex genotypes of faba bean (Vicia faba L.

) viz.

, 1- FLIP06-005FB, 2- FLIP06-016FB, 3- FLIP11-088FB, 4- FLIP11-092FB, 5- Line46-01 and 6- Local Check in a full diallel crossing program (Griffing 1956) first method (Model I) to produce F1 hybrids, of thirteen single hybrid genotype planted.

The parents and F1 hybrid were tested by utilizing Randomized Complete Block Design (R.

C.

B.

D.

) with three replications to carry out an experiment in the Field Crop department, College of Agriculture and Forestry, Mosul University.

The study aimed to evaluate the performance of hybrids and their parents for identify promising hybrids and the objectives to develop single cross hybrids in addition to estimate genotypic and phenotypic correlations and path coefficient analysis for the studied characters.

Results showed that parents and F1 were significantly different for all the studied characters, parent 4- FLIP11-092FB was found to be the best for green pods yield and seeds yield and parent 3- - FLIP11-088FB for the biological yield, whereas the hybrid F1 (6×3) for green pods yield and seeds yield and the hybrid (5×3) for the biological yield.

There were appositive significant genotypic and phenotypic correlations between the seeds yield and plant high, green pods yield, biological yield, seed index and 100 seed weight.

The higher genotypic and phenotypic a correlation was found between 50% flowering date and biological yield.

The genetic path coefficient analysis showed that the 100 seed weight had a higher direct and indirect effects for seeds yield, This character can be used in the program of plant breeding.
