Soybean Yield Formation Physiology – A Foundation for Precision Breeding Based Improvement

The continued improvement of crop yield is a fundamental driver in agriculture and is the goal of both plant breeders and researchers. Plant breeders have been remarkably successful in improving crop yield, as demonstrated by the continued release of varieties with improved yield potential. This has...

Plant breeders have been remarkably successful in improving crop yield, as demonstrated by the continued release of varieties with improved yield potential.
