Interpretive Summary: Reliable and consistent development of high-yielding sugarcane cultivars with enhanced resistance or tolerance to biotic and abiotic stresses is important for sugarcane growers. In the CP program in Florida, decisions to advance and commercially release sugarcane genotypes in the final three selection stages (i.e., Stages 2, 3, and 4) are made by a variety committee of sugarcane grower and scientists from the public and private sectors. Members of this committee recommended releasing CP 09-1430 for the Florida muck soils at the variety committee meeting in June 2016 because of its high yields of cane and sucrose on muck soils compared with commercial reference cultivar CP 89-2143. In multiple field trials, it demonstrated resistance or tolerance to most major and minor sugarcane diseases, but does have susceptibility to brown rust and ratoon stunting disease. The high sucrose and cane yield for CP 09-1430 was mainly associated with high mean stalk weight resulting in significantly higher tonnage than the reference cultivars. CP 09-1430 demonstrates freezing tolerance at, or exceeding, the levels as observed across five reference cultivars; indicating an ability to withstand freezing temperatures similar to the ones described in this registration.

Technical Abstract: ‘CP 09-1430’ (Reg. No. CV-178; PI 686940 sugarcane (a complex hybrid of Saccharum spp.) was developed and released (6 Jun. 2016) through cooperative research conducted by the USDA-ARS Sugarcane Field Station , Canal Point, the University of Florida, and the Florida Sugar Cane League, Inc. for use on muck soils. The clone results from CP cross # 06-0576 (CPCL 00-6756 x CP 01-2390), and possessed the following agronomic traits: high cane and sucrose yields; high economic index, and acceptable commercial recoverable sucrose on muck soils. It is a very good germinator, particularly under wet planting conditions. Results of replicated trials on muck soils (2012, five locations; 2013, two locations) included 19 total harvests for the three crop stages. Yield comparisons to check varieties (CP00-1101, CP78-1628, and CP89-2143) indicated CP 09-1430 had significantly higher means than CP89-2143 (P = 0.10) for the following: stalk weight (1.38 kg stalk-1); second ratoon cane yield (129.4 Mg ha-1); mean cane yield of three crops (146.4 Mg ha-1); sugar yield [plant cane (21.9 Mg ha-1), second ratoon (13.1 Mg ha-1), and overall mean for the three crop harvests (17.6 Mg ha-1)]; and the economic index (3,137 $ ha-1). CP 09-1430 has moderate freeze resistances. It is susceptible to brown rust, scald, and ratoon stunting disease. It is moderately resistant to orange rust, smut, and Sugarcane yellow leaf virus; with full resistance to mosaic. It is moderately resistant to freezing temperatures.
