CYTOLOGICAL BASIS OF RACIAL DIVERSITY IN INDIAN MAIZE: AN OVERVIEW

Published on

Cytolojpcal characterization of Indian maize races based on knob composition reveals
certain well defined knob complexes in northeastern and northwestern regions of the
Himalayas. The frequency as well as combination of various knob positions was found to
be characteristic of different races and a specific pattern of geographic distribution of these
knobs was observed. Two lineages of Himalayan maize could be established on the basis
of knob pattern: a) Nal-Tel-Chapalote complex having very high knob number, and b)
Confite Morocho with very low knob number. Both pre- and post-Columbian introduction
of maize in northeastern Himalayan (NEH) region is postulated.
