George-Jaeggli, Barbara. ACIAR Improving Postrainy Sorghum Varieties Grain and Fodder in India. Lead Agency: Department of Employment, Economic Development and Innovation (DEEDI).

Project Start: 1 July 2008

Project End:30 June 2012

Abstract

Sorghum grown in India in the post-rainy season (Rabi) relies on residual soil moisture, and the crop is commonly exposed to terminal drought stress. But there is a ready market for its high-quality grain and stover (used as fodder on dairy farms). Steps to improve productivity while maintaining quality offer an attractive opportunity for sorghum farmers to improve their incomes. Genetically improving the efficiency of using stored soil moisture is a prime target to maximise grain/stover production and quality of Rabi sorghum. This project aims to achieve this through the application of DNA sequences known as quantitative trait loci (QTLs).

The project scientists will introduce marker-assisted introgression of stay-green QTLs into sorghum lines, enhancing both the quality and the quantity of grain/stover of postrainy sorghum. They will also use modelling to identify the key physiological traits involved in a higher, more stable yield across water-limited environments of India and Australia, and the key stay-green QTLs contributing to these traits.

The publicly available QTL isolines lines developed in this project will be the basis of new varieties to be bred in a subsequent phase.
