Genetic diversity among plantagos. XIX. Studies on primary trisomics of Plantago lanceolata L.

Trisomics for two chromosomes have been isolated in the progeny of cross between disomic and aneuploid individual in Plantago lanceolata L. The karyotypic analysis and meiotic studies has revealed their primary nature and identification as Triplo-1 and Triplo-4. Attempt has been made to study impact of trisomy on plant phenotype and fertility. Due to the phenotypic plasticity within the species even at disomic level, the morphological variations induced by trisomy do not become vivid.
