Abstract: Development of climate resilient crop varieties with enhanced tolerance to heat, drought, salinity, excess water / flooding, chilling is essential in order to sustain and improve crop yields to manage the challenges of climate change (Maheshwari et al. 2015).Introgression of abiotic tolerant genes into climate resilient varieties depends upon the availability of potential sources from wild relatives and their exploitation.Saccharum spontaneum L. has been utilized in sugarcane breeding since 1912 due to its wider adaptability under biotic and abiotic conditions.The genetic stock AS 04-1687 having drought and waterlogging tolerance is an interspecific hybrid derived from a cross between sugarcane commercial cultivar (BO 102) and the wild species S. spontaneum (IND 84-337) having the cytotype 2n=56 which was not used in the breeding programme earlier.The hybrid AS 04-1687 is characteristic with erect habit, purple coloured cylindrical internode and leaf sheath which is tight and glabrous with brown coloured dewlop and deltoid auricle (Fig. 1).
