Identification of resistance to red rot in interspecific and intergeneric hybrid clones of sugarcane [Full subscriber]

Abstract The incorporation of red rot resistance in sugarcane is the foremost priority in Indian sugarcane breeding programs. An ideal parent should possess a high sucrose content, good agronomic traits, and red rot resistance. To enrich the parental pool with resistant sources having diverse backgrounds, many interspecific hybrid (ISH) clones and intergeneric hybrid (IGH) clones were identified in the previous decades from the 1960s and were utilised in the National Hybridization Programme. To further augment red rot resistance in the parental clones, we selected 27 ISH clones developed at ICAR-SBI Coimbatore and evaluated them against the prevailing Colletotrichum falcatum pathotypes…
