The strong competitive role of 2n pollen in several polyploidy hybridizations in Rosa hybrida

Abstract Background 2n pollen play a strong competitive role in hybridization and breeding of multiploids in Rosa hybrida. The ploidy inheritable characteristic of ‘Orange Fire’ × ‘Old Blush’ were analyzed. Result The results of the cytological observations indicated that 2n pollen developed from th...
