Identification of new genetic resources for drought tolerance-related traits from the world <i>Erianthus</i> germplasm collection.

ABSTRACT: Drought is one of the most complex abiotic stress factors and significantly affects sugarcane production worldwide. With an objective to identify drought-tolerant wild sugarcane germplasm for sugarcane improvement, a set of 223 diverse Erianthus clones collected from seven different countries were assessed for drought tolerance-related traits at the formative stage. A drought association panel of 91 Erianthus clones with differential drought response was developed for genomic studies to identify marker-trait associations. Drought-tolerant Erianthus clones maintained high chlorophyll fluorescence (F _v/F _m) and relative water content and chlorophyll content, and were able to regulate photosynthetic rate as well as canopy cooling to sus
