Abstract

Detailed karyotypic studies have been done in two critically endangered and endemic Crinum species viz. C. brachynema Herb. and C. woodrowii Baker, which belong to two ploidy levels 2x and 4x respectively. The mean chromosome length (MCL) for C. brachynema and C. woodrowii is more or less same. Both the species fall under 3b category of Stebbins classification and exhibit moderately symmetrical karyotype. The similarity in chromosome morphology is in contrast with the marked phenotypic differences exhibited by these two species which in fact belong to two different sections. As these species are under tremendous anthropogenic influence, this communication is an attempt to provide basic chromosome data on these species with the aim that this data can be useful in future breeding work as Crinums have great ornamental potential. This may finally help in domestication of these neglected species and will ultimately lead to their conservation.
