ردیابی لوکوس‌های چند شاخگی در آفتابگردان زراعی

Hybrid production in sunflower takes the advantage of male sterility system. In the system, restorer lines are cultivated in vicinity of male sterile lines. Multi-branching nature of restorer lines is required for a successful pollination. As there are no sequences available for branching locus in sunflower, sequence information for branching genes in other plants was used to define TRAP (target region amplification polymorphism) markers to monitor branching locus (loci) in sunflower inbered lines. The results indicated that the markers are efficient to differentiate between branched and non-branched sunflower lines.
