Application of molecular marker technologies for maize improvement in India - present status and prospects

Application of molecular marker technologies for maize improvement in India - present status and prospects - Mexico, DF (Mexico) CIMMYT : 2004 - p. 73-81 - Printed
Concerted efforts by maize researchers in India from diverse institutions across the country, particularly since 1960s, have led to significant advances in improving maize production and productivity in the country. However, there is considerable scope for further enhancing the efficiency of maize breeding in the National Agricultural Research System through judicious integration of biotechnology. The inception of the Asian Maize Biotechnology Network (AMBIONET) in India in 1999 has provided tremendous impetus in this direction. Our research efforts through this Network, facilitated by CIMMYT, have led to: (i) molecular profiling of 58 inbred lines developed by various maize breeding units in India, using microsatellite or simple sequence repeat (SSR) markers; (ii) detailed analysis of genetic diversity in Indian maize inbred lines using various datasets (morphological, per se performance and molecular); and (iii) mapping of quantitative trait loci (QTL) and identification of SSR markers linked to genomic regions conferring tolerance to downy mildew diseases in India. Efforts are also being made to apply molecular marker strategies for enhancing drought tolerance under Indian conditions. The progress made so far in application of molecular technologies, particularly through AMBIONET, and the potential areas where marker technologies can further aid in maize breeding programs in India shall be discussed.
