Abstract

Thirty six castor inbred lines were studied for agro-morphological characterization, the entire group of inbred lines showed wide range of genetic variation for qualitative traits like anthocyanin pigmentation on hypocotyl and younger leaves, bloom/waxiness, stem colour, types of internodes on main stem, leaf shape, petiole surface, types of flowers on primary spike, spike shape, spike compactness, spines on capsules, location of branches, branching pattern, seed shape, seed coat colour, seed mottling and seed caruncle and quantitative traits like days to 50% flowering, plant height, primary spike length, no. of nodes to primary raceme, 100 seed weight. The hypocotyl anthocyanin pigmentation showed close association with presence of anthocyanin pigmentation on young leaves. About 97% of inbred lines exhibited double bloom nature which is an important trait for drought tolerance in castor.
