Karylogical Studies of Kallar Grass (Leptochloa fusca L.)

Abstract

Detailed karyotypic studies of Leptochloa fusca L. revealed 2n=2x=20 chromosomes. All the chromosomes possess a centromere in nearly sub-median (nsm) and nearly median (nm) region. The chromosomes are very small and structurally similar to rice chromosomes except for minor differences in the number of secondary constrictions and complete absence of sub-terminal chromosomes in L. fusca (kallar grass).
