Interpretive Summary:

Technical Abstract: The Agricultural Research Service of the United States Department of Agriculture, the Louisiana Agricultural Experiment Station of the LSU Agricultural Center, and the American Sugar Cane League of the U.S.A., Inc., working cooperatively to develop improved sugarcane varieties, have jointly developed and hereby announce the release of a new sugarcane variety, Ho 13-739, for commercial planting in the summer of 2020. Ho 13-739 is an offspring of the cross between Ho 06-9610 and HoCP 04-838 made at Houma, LA in 2008 and assigned at Houma (Ho), Louisiana in 2013. The variety Ho 13-739 produced similar sugar yields (lbs/acre) when compared to L 01-299, the most widely grown commercial variety in Louisiana, in each crop individually and over a complete crop cycle (Table 1). In comparisons with L 01-299 in 30 plant-cane outfield evaluations, Ho 13-739 had significantly higher sugar/ton (275 vs. 262 lbs.). It produced less stalks/acre (24,204 vs. 28,843), but its individual stalk weight was significantly higher (2.69 lbs. vs. 2.30 lbs.). In 21 first-ratoon outfield evaluations, Ho 13-739 yield was similar to L 01-299 in sugar/acre (8,284 vs. 8604 lbs.) less for cane/acre (30.8 vs. 33.4 tons), but more for sugar/ton of cane (268 vs 257 lbs.). Similar to the plant-cane results, Ho 13-739 produced less stalks/acre, when compared to L 01-299 (27,780 vs. 34,822), but its stalk weight was higher (2.25 vs 1.95 lbs.). In ten second-stubble outfield trials, Ho 13-739 sugar yield was equivalent to L 01-299 (7274 vs. 7438 lbs./acre.), but sugar/ton cane (270 vs 251 lbs.) and stalk weight (1.74 vs 1.52 lbs.) were both higher, when compared to L 01-299. Ho 13-739 produced lower tons cane/acre (27.3 vs 30.0 tons) and stalks/acre (31,661 vs 39,990), when compared to the industry standard. From an average of 42 tests Ho 13-739 had a fiber percentage of 11.5%, which is 8% lower than L 01-299, indicating favorable milling ability. Ho 13-739 matured (increase in TRS lbs./ton) earlier than L 01-299 and every cultivar in the maturity test except for L 01-283. Based on one test, Ho 13-739 had moderate to good cold tolerance, slightly less than HoCP 96-540. Ho 13-739 is resistant to smut caused by Sporisorium scitamineum, mosaic caused by Sorghum mosaic virus (SrMV), and leaf scald caused by Xanthomonas albilineans. It has moderate susceptibility to brown rust caused by Puccinia melanocephala and ratoon stunt caused by Leifsonia xyli subsp. xyli. The new variety has moderate susceptibility to sugarcane borer, Diatraea saccharalis. Seed cane of Ho 13-739 will be distributed by the American Sugar Cane League of the U.S.A., Inc., in accordance with procedures to be announced to all sugarcane growers in Louisiana on or after July 1, 2020. Inquiries concerning seed cane should be directed to the American Sugar Cane League, 206 East Bayou Road, Thibodaux, LA 70301. Neither the United States Department of Agriculture nor the Louisiana Agricultural Experiment Station has seed cane available for distribution.
