Abstract:
ضمن البحث دراسة عشرة اصناف من الحنطة الناعمة (حنطة الخبز) Triticum aestivum L. من الاصناف العراقية والمدخلة الى البلد من قبل وزارة الزراعة العراقية والمزروعة في محافظة النجف وهي : الشام6 , ابوغريب, تموز2, تموز3, العراق, النور, اللطيفية, اباء 99, الرشيد, و| The study included studying ten cultivars of soft wheat (wheat bread) of several types the Iraqi, foreign and imported types into the country by the Iraqi Ministry of Agriculture and cultivated in the province of Najaf, they are : Sham 4, Abu Ghraib, Tamoz 2, Tamoz 3, Iraq, Alnoor, Latifiya, Ebaa 99, Rasheed and Alforat to study the genetic stability using cytological studies. Cultivars were grown in Petri dishes and pots for the cytological studies that included studying the number of chromosomes in the somatic cells at the root tips and the chromosomal behavior during meiosis of the mega spores of the Pollen Mother Cells (PMCs). The cytological studies regarding the number of somatic chromosomes in the meristematic cells of the root tip revealed that they were in genetic stability regarding the level of chromosomal number and in a state of Eupliod in all the investigated cultivars. They also showed that the chromosomal behaviors during meiosis of the pollen mother cell (PMCs) was bivalent representing organized chromosomal behavior in the investigated cells which is regarded as an indicator and a proof of genetic stability of the studied cultivars. During the study, the genetic cultivars, using 15 primers of simple sequence repeat (SSR), gave all polymorphic between the cultivars and produced polymorphic 39 alleles at average of 2.6 for each locus, showed the genetic adendrogram of ten cultivars was performed by two groups in which the percentage of similarity between them was 75% as the results showed that the closest cultivars to each other were Tamoz 2 and Ebaa 99 which is the same genetic dimension between Tamoz 3 and Ebaa 99 reached 0.107 and by the similarity 89%, while the two cultivars alsham4 and Al - Rasheed were divergent (0.333) with 67% similarity.
