Table 2 Different ploidy material induction efficiency

From: Genetic characteristics and ploidy trigger the high inducibility of double haploid (DH) inducer in Brassica napus

Cross combination Paternal ploidy Effective seed setting rate (number of seeds/(number of effective siliques*25))% Number of F1 generation survived plants/number of seeds (%) Number of waxless plants/total number of plants Number of tetraploid plants/total number of plants Induction rate (%) Selfing male parent survival rate (%)
