Registration Of 'Yt 09-13' Sugarcane

'Yuetang 09-13' ('YT 09-13') (Reg. no. CV-197, PI 695070) sugarcane (a complex hybrid of Saccharum spp.) was selected and evaluated by the researchers of institute of Bioengineering, Guangdong Academy of Sciences, from the progenies of a cross between YT 93-159 (female) and ROC 22 (male). It was released to the growers in Guangdong Province, China, in July 2017. Yield data from three crop cycles (plant cane, first ratoon, and second ratoon) of 15 regional trials during 2015-2017 showed that the average cane yield of YT 09-13 was 100.66 Mg ha(-1), about 3.41% higher than that of ROC 22 (the check cultivar); the average sugar yield was 14.88 Mg ha(-1), about 6.82% higher than that of ROC 22 (the check cultivar); and the average fiber content was 10.41%. YT 09-13 is tolerant to drought and resistant to smut, Sugarcane mosaic virus, and brown rust diseases. YT 09-13 is a suitable cultivar for planting and distributing in the main sugarcane areas of Hainan, Guangdong, Guangxi, and Yunnan.
