“…Freeze‐tolerance trials involving commercial and near‐commercial cultivars are established annually at the USDA Research Farm at Schriever. Two cultivars, LCP 85‐384, representing good stalk freeze tolerance, and TucCP 77‐42 (Mariotti et al, 1991), representing poor stalk freeze tolerance, are included as controls. Following a damaging freeze, changes in juice pol (sucrose), pH, titratable acidity, and deterioration‐related products (Legendre et al, 1985) are monitored, usually on a biweekly basis.…”

‘HoCP 00‐950’ (Reg. No. CV‐135, PI 654823) sugarcane (a complex hybrid of Saccharum officinarum L., S. spontaneum L., S. barberi Jeswiet, and S. sinense Roxb. amend. Jeswiet) was selected and evaluated by the USDA‐ARS, working cooperatively with the Louisiana State University AgCenter, and the American Sugar Cane League, Inc. It was released to growers in Louisiana in April 2007. In 67 machine‐harvested trials on light‐ and heavy‐textured soils from 2004 to 2007 (plant‐cane through third‐ratoon crop) averaged over nine southern Louisiana locations, HoCP 00‐950 produced 5% more sugar and had 6% higher sugar content than the industry standard, ‘HoCP 96‐540’. In plant‐cane and ratoon‐crop maturity tests harvested in 2007, HoCP 00‐950 had significantly higher sugar content than HoCP 96‐540 across all harvest dates, with 35% higher sugar content at the outset of the harvest season (late September). HoCP 00‐950 is resistant to brown rust (Puccinia melanocephala), smut (Ustilago scitaminea), leaf scald (Xanthomonas albilineans), and mosaic diseases. It is susceptible to the sugarcane borer (Diatraea saccharalis) and should not be planted in areas where pesticide use is restricted. The early maturity characteristic of HoCP 00‐950 provides growers with a variety that can produce profitable sugar yields early in the milling season without the need to apply a chemical ripener.

“…Both cultivars sustained a decrease in TRS of only 3%. Three cultivars, L 99‐226, ‘TucCP 77‐42’ (Mariotti et al, 1991), and L 99‐233, sustained greater losses in TRS at 27, 27, and 36%, respectively. Therefore, HoCP 04‐838 is recommended for cultivation in the upper reaches of the area that sugarcane is grown, an area that is subject to lower winter temperatures.…”

HoCP 04-838' (Reg. No. CV-181, PI 687221) sugarcane (interspeciic hybrids of Saccharum spp.) was selected and evaluated by scientists at the USDA-ARS, working cooperatively with the Louisiana State University Agricultural Center, and the American Sugarcane League, Inc., from a cross between the female parent 'HoCP 85-845' and the male parent 'LCP 85-384'. It was released to growers in Louisiana in May 2011. Yields from three crops (plant, irst ratoon, and second ratoon) at 12 farm locations compared well with HoCP 96-540, the most widely grown cultivar in Louisiana during that time. The plant-cane sucrose yield (Mg ha −1 ) of HoCP 04-838 was equivalent to HoCP 96-540, and cane yield was signiicantly higher than HoCP 96-540. HoCP 04-838 is earlier maturing than HoCP 96-540 but not as early as 'HoCP 00-950', the high sucrose standard cultivar. Mature stalk cold tolerance was similar to LCP 85-384, the cold tolerance standard. HoCP 04-838 is resistant to smut, mosaic caused by Sorghum mosaic virus, brown rust, and ratoon stunt. HoCP 04-838 is moderately resistant to leaf scald and is susceptible to Sugarcane yellow leaf virus. It is resistant to sugarcane borer. HoCP 04-838's high yield potential and cold tolerance make it a useful addition to existing commercial sugarcane cultivars in Louisiana.

“…Houma clones selected in basic breeding were previously assigned US [United States] breeding numbers, but basic selections are now given Ho designations. Basic clones typically were used in the breeding program as nonrecurrent parents for backcrossing with selected interspecific hybrids used as recurrent parents [ 10 ], and cultivars were often the recurrent parent. In practice, crosses usually were constructed taking into consideration the parental pedigrees to minimize potential effects of inbreeding.…”

“…Houma cultivars from CP 65-357 to CP 79-318 received the CP name designation even though germplasm had been selected at Houma. This included the BC 1 cultivar TucCP 77-42 which was selected in Argentina from a cross made at Houma [ 10 ]. Cultivars released from the LSU program have an “L” name designation while those from the Houma program have an Ho name designation.…”

Historical Use of Cultivars as Parents in Florida and Louisiana Sugarcane Breeding Programs

Sugarcane (Saccharum L. spp. hybrids) growers depend on breeding programs for new, high-yielding cultivars that have resistance to abiotic and biotic stresses, so breeders continually seek out widely adapted, high yielding germplasm to be used as parents for their programs. Cultivars are sometimes used for this purpose, but their use may be minimized to prevent genetic diversity erosion. The purpose of this study was to determine the importance of cultivars as parents in three USA (one in Florida and two in Louisiana) sugarcane breeding programs by quantifying the percentage of cultivars that had these parental groupings based on published registrations and crossing records. The percentage of cultivars with at least one commercial parent for each program was 81.8%, 77.5%, and 64.3% for the Houma (Ho), Louisiana, Canal Point (CP), Florida and Louisiana State University (LSU) programs, respectively, but cultivars were recently used as parents in only 11.8% (Ho), 16.39% (CP), and 34.3% (LSU) of crosses. The results indicate that the CP and Ho programs should consider increasing the use of cultivars as parents in their breeding programs to increase the probability of selecting potential commercial genotypes, but this should be balanced with high diversity crosses to avoid the loss of diversity.
