تقييم الأداء الحقلي و الوراثي لتراكيب وراثية منتخبة من الطماطة Lycopersicon esculeuntum Mill.

Abstract EN

The study was conducted at the fields of the Department of Horticulture and Landscape Gardening, College of Agriculture, University of Baghdad during the growing seasons of 2013- 2014 .for Performance of Evaluation Vegetative growth and yield traits and estimate some important genetic parameter on seven selected breed of tomato which (S1-S7 ) Pure line.

the results found significant differences between breeds in all study trails except clusters flowering number .S1 significantly plant length which reached 227.3 .Also S1,S2 and S4 were significantly increased the number fruit for plant, Fruit weight Increased in S3 ,S6 and plant yield.

Increased in S1, S4 ,S5.

Genetic variation values were low in Floral clusters , TSS and fruit firmest and medium in Stem diameter .

and high in the rest of traits .Percentage of inheritance in the broad sense was height ,in all traits except Floral clusters and fruit firmest 8.41%, 33.10% respectively and the environmental variation was higher than genetic variation in this two traits.

while phenotype variation values were low in TSS and fruit ferment and high in the rest of the study traits.

Analysis Hierarchical clustering showed the Average convergence breeds S3 and S6 also between S2 and S4 While diverged between S1, S5, S7.
