Table 1 Numbers of diploid and triploid F1 plants that segregated for lacecap and mophead inflorescences

From: Rapid identification of inflorescence type markers by genotyping-by-sequencing of diploid and triploid F1 plants of Hydrangea macrophylla

Putative ploidy Lacecap Mophead Intermediate Non-flowering In total
