اختبار و تشخيص متغايرات وراثية في الطماطة بتأثير الصعق الكهربائي و الصديوم أزايد تحت ظروف الإجهاد الملحي 2. الصفات النوعية للثمار

Abstract EN

An experiment was conducted at the Department of Horticulture – Agriculture College –Baghdad University.

during two seasons of 2013 – 2014 to Diagnosis and testing of genetic variable in tomato Lycopersicon esculantum .Mill under salt stress conditions .

It have been used tomato seeds for Red ston seeds for sprouted were soaked in distilled water for 8 hours then conducted the following treatment in Sodium azide (NaN3): seeds sprouted soaked in sodium azide solution and Electric Shock treatment Sodium azid interaction with electric shock treatment in first season planting in three levels of water salinity 1.9, 4, 8 dsm.

in second season individual plant selection planting in two levels of water salinity 2, 8 dsm ˉ¹.

A Nested design was used with three replicated.

The results showed that Selection 4SA+3A significantly increased fruit firmness (6.17) kg.cm² .

TSS increased in selection 6A while total acidity increased significantly in selection 9A(0.94 %) fruit lycopen contact significantly increased in control treatment (6014) mg.

100 grams.

Conclusions found relationships between mutagenesis and water salinity in Fruit Quality Traits.
