Fig 4. Cross diagram showing the results of the different crosses performed within the genetic bridge approach starting with crosses between C. baccatum and the bridge species.

(A) First cross tables indicate the crossability degree of C. baccatum with C. chinense and C. frutescens, (B) Second cross tables indicate the crossability degree of the hybrids obtained with C. annuum. Numbers over the cells indicate percentage of fruit set over an average of 25 artificial pollinations. Green indicates non-viable crosses, where no fruits were obtained (0% of fruits set, not indicated as number); blue indicates fruit set but non-viable seeds; red indicates fertile hybrids with normal development; and grey indicates hybrid inviable plants.
