Abstract

Kranz anatomy studied among Panicum maximum ac-cessions showed wide variation for chloroplast in bundle sheath (BS), mesophyll and mestome. Geno-types in clusters E and F, with <20% pigmentation in BS, had lineage with P. prionitis, P. rivulare, P. laxum, P. hylacicum and P. bisulcatum, whereas genotypes in clusters B, C and D with high pigmentation were C4 types having lineage with P. antidotale, P. coloratum and P. miliaceum. Genotypes with ~50% pigmentation in cluster A were intermediate types and might have evolved either through intraspecies crossing or species like P. milioides, P. decipens, P. schenckii and P. petersoni.
