Genotypic diversity in species of Scilla.
Two cytotypes of Scilla indica and three other species, namely S. nervosa, S. siberica and S. vindobonensis were investigated. The estimation of nuclear DNA content was utilized as a measure of genetic diversity at inter- and intraspecific levels and as an index of the trends of evolution. S. siberica with a very high DNA value was regarded as indicative of a primitive state. The heavy intraspecific difference in DNA content in S. indica has been attributed to amplification of the DNA.
