Registration of ‘CPSG‐3481’ Sugarcane

Abstract

‘CPSG‐3481’ (Reg. No. CV‐165, PI 676023) sugarcane (a complex hybrid of Saccharum spp.) cultivar was developed through cooperative research conducted by the Shakarganj Sugar Research Institute in Pakistan and the USDA‐ARS Sugarcane Field Station in the United States and released to growers for loam soils in Pakistan in September 2012. CPSG‐3481 was developed from a biparental cross (CP 81‐1238 × CP 85‐1308) made at Canal Point (CP), FL, USA, in December 1992, and selection process was made at the Shakarganj Sugar Research Institute, Punjab, Pakistan, in 2001–2011. CPSG‐3481 was commercially released by the variety evaluation committee of sugarcane scientists from the public and private sectors in the sugarcane production region (Punjab, Pakistan) in 2012 because of its high cane and sucrose yields and high commercial recoverable sucrose on loam soils and its acceptable levels of resistance to red rot (caused by Colletotrichum falcatum Went), brown rust (caused by Puccinia melanocephala Syd. & P. Syd.), pokkah boeng (caused by Fusarium moniliforme J. Sheldon), Sugarcane mosaic virus, and smut (caused by Ustilago scitaminea Syd. & P. Syd.) in Pakistan. Based on results of nine harvests of three crops (plant cane, first ratoon, and second ratoon) in the final‐stage replicated yield trials conducted at three locations on loam soils and compared with a reference cultivar HSF‐240, CPSG‐3481 had 19.4% higher (p < 0.030) cane yield, 19.7% higher (p < 0.001) commercial recoverable sucrose, 43.0% higher (p < 0.001) sucrose yield, and 19.4% greater (p < 0.001) economic index.
