A population consisting of 151 F₂ was developed from a cross of two agronomically elite inbred seed parents, ICMB841 and 863B . The two parents are known to produce hybrids that distinctly differ in their response to post-flowering drought stress. Parent 863B was bred from Iniadi landrace material from Togo and was selected for this study based on its combination of agronomic eliteness and superior combining ability for grain filling under terminal drought stress conditions. Parent ICMB841 is the maintainer of the female parent of several high yielding hybrids that are widely grown in India, but lack tolerance to terminal drought stress. A linkage map consisting of 91 markers including 30 microsatellite markers comprises seven linkage groups and covers 476 cM with an average map distance between loci of about 5.2 cM. The marker and map data are kindly provided by Drs. R. S. Yadav and K. M. Devos.
