Stalk rot complex of maize (Zea Mays L.) caused by Macrophomina phaseolina (Tassi) Goid and Fusarium verticilloides (Sacc) Nirenberg reduces yield directly by affecting the physiological activity of the plants and finally cause lodging, which is the main reason of economic losses. Screening of Indian maize inbreds for the resistance to pathogen was done using 34 Simple Sequence Repeats (SSR) markers available in database. Among these SSR markers, two markers viz. SSRZ 135, and SSRZ 319 showed polymorphism for resistance to stalk rot. The marker SSRZ 319 located on chromosome 1 distinguished the resistant lines H 109, P 503, P 408 and E 618 from the susceptible lines viz., H-8, P 320, P 373 and 18834. Resistant genotypes identified in the study would serve as potential donors in the stalk rot resistance breeding programme. Further, QTL qRfg2 with most likely presence in the Indian maize inbred lines can be transferred to elite inbreds using marker-assisted selection.
