Abstract AR
تعد قوة الهجين من أهم الظواهر التي لفتت اهتمام و انتباه الكثيرين من علماء و باحثين و مشتغلين في مجال تربيه النباتات بمختلف أنواعها بهدف تحسينها، لمعرفة أسباب حدوثه، و قواعده، و كيفية الاستفادة منه في تحسين العمليات الإنتاجية لمختلف المحاصيل نوعا و كما، و هي ظاهرة ناتجة عن تفاعل مواد وراثية نتجت في بيئات مختلفة يستخدمها مربي النبات بالشكل المناسب و الأفضل إلانتاج الهجبن، و تكون قوة الهجين في ذروتها في أفراد الجيل الأول الناتجة من عملية التضريب بين النباتات المختلفة ثم تتقلص و تتلاشى في الأجيال الالحقة، حيث تحدث في جميع أجناس و عوائل النباتات متعددة التلقيح.
بنوعيه، الا أنها أكثر فعالية و تكرارا في النباتات الملقحة الخليطة، حيث تمتلك اختالفات وراثية كبيرة ، و هذا الخليط من المورثات هو أساس القوة و الحيوية لها.
وتكون قوة.
الهجين أكثر وضوحا عند زيادة التباعد.
الوراثي بين الآباء الداخلة في التهجين.
و لضمان الحصول على قوة هجين عالية و متفوقة فإن أغلب المصادر تشير إلى إدخال آباء ذات أصول وراثية متباعدة في برامج إنتاج الهجن
Abstract EN
Heterosis is a phenomena that have received the attention of geneticists and researchers in the field of plant breeding and improvement, in an attempt to find out the reasons for their occurrence, their rules and how to use them to improve plant characters and increase production.
It is a phenomenon resulting from the interaction of genetic materials used by plant breeders in an appropriate manner to produce hybrids.
The heterosis is at its peak in the first generation and then decreases in the later generations, as this phenomenon occurs in self and cross -pollinated, but it is more powerful and frequent in cross-pollinated plants, as they contain large genetic variance, and that this genetic mixing is the basis of their strength and vitality.
The strength of heterosis is more pronounced when the genetic divergence between the parents involved in the hybridization is increased.
In order to ensure obtaining high hybrid vigor, most sources refer to the introduction of parents with divergent genetic origins in the hybrid production Heterosis is a phenomena that have received the attention of geneticists and researchers in the field of plant breeding and improvement, in an attempt to find out the reasons for their occurrence, their rules and how to use them to improve plant characters and increase production.
