Variation and fitness of hybrid F 4 between glyphosate‐tolerant soybeans and three wild soybean populations from Northern China

Key Points

• The study aims to investigate how hybridization between glyphosate-tolerant soybeans and wild soybean populations affects fitness-related traits.
• Assessed hybrid F4 populations created from glyphosate-tolerant soybeans and wild soybean species.
• Examined trait-segregating and segregation-distorted characteristics in hybrids.
• Evaluated ecological adaptations and establishment potential in wild soybean habitats.
• Hybrid F4 populations displayed varying levels of fitness compared to parent strains.
• Trait-segregating hybrids may adapt better to diverse ecological niches.
• Segregation distortion is thought to enhance establishment capability in wild populations.
