Interpretive Summary: CPCL 00-6131 sugarcane cultivar was developed by the private United States Sugar Corporation [USSC] breeding program and also through cooperative research conducted by the USDA-ARS, the University of Florida, and the Florida Sugar Cane League, Inc. CPCL 00-6131 was not released in Florida because of its susceptibility to brown rust (Puccinia melanocephala H. & P. Sydow) and the low yield of commercial recoverable sucrose. CPCL 00-6131 was introduced, advanced and released in Guatemala by the Guatemalan Sugarcane Research and Training Center (CENGICAÑA). CPCL 00-6131 was released to Guatemalan growers in 2019 because of its high cane and sucrose yield both at plant cane and ratoons crops; acceptable resistances to both brown and orange rusts, leaf scald, smut, dry stalks or wilt, and to Sugarcane mosaic virus strain E (mosaic). CPCL 00-6131 had 12.2% higher sugar yields than CP72-2086 in multiple field trials in Guatemala.

Technical Abstract: ‘CPCL 00-6131’ (Reg. no. CV-220, PI 705850) is a sugarcane hybrid cultivar (a complex hybrid of Saccharum spp.) that was developed in two countries (United States and Guatemala). In the United States, the crossing and seedling selection were done by United States Sugar Corporation (USSC); advanced trials of the selected clones were conducted by the USDA-ARS Canal Point (CP) sugarcane breeding program. In Guatemala, the further introduction, advanced field tests and final release were carried out by the Guatemalan Sugarcane Research and breeding program (CENGICAÑA). CPCL 00-6131 was not released in Florida because of its susceptibility to brown rust (caused by Puccinia melanocephala H. & P. Sydow) and the low yield of commercial recoverable sucrose than the reference cultivar. After testing in Guatemala, CPCL 00-6131 was released in 2019 because of its high cane and sucrose yield both at plant cane and ratoons crops under the Guatemala growth environment. CPCL 00-6131 ranked first, being significantly greater than the reference cultivar ‘CP 72-2086’ in the second ratoon and the combined crops. It has acceptable resistance to wilt or dry stalks caused mainly by Cephalosporium sacchari (Bult.) = Fusarium sacchari (Gams.), smut (caused by Ustilago scitaminea Sydow & P. Sydow), leaf scald [caused by Xanthomonas albilineans (Ashby) Dowson], brown rust and orange rust (Puccinia kuehnii E.J. Butler) and Sugarcane mosaic virus strain E (the causal agent of mosaic).
