Summary

Chloroplast DNA from 44 lines of 16 wild and 7 cultivatedSolanum species were compared by restriction endonuclease analysis. Seven chloroplast genome types were identified among them by 5 restriction enzymes: Type A (S. tuberosum ssp.andigena andS. maglia); Type S (S. goniocalyx, S. phureja, S. stenotomum, S. ×chaucha and a line of ssp.andigena); Type C (S. acaule, S. bukasovii, S. canasense, S. multidissectum andS. ×juzepczukii); Type T (S. tuberosum ssp.tuberosum); Type W (other wild species); Type W′ (S. chacoense f.gibberulosum) and Type W″ (S. tarijense). From this cytoplasmic identification, it was concluded thatS. goniocalyx, S. phureja, S. ×chaucha and ssp.andigena were derived fromS. stenotomum or its primitive type, which may have originally evolved itself fromS. canasense. The chloroplast genome of the European potato, however, was introduced from the Chilean potato, which might have been primarily constructed with the nuclear genome from ssp.andigena and with cytoplasm from other species. The cytoplasmic donor of the Chilean potato could not be determined.
