“…Female × male variance (SCA) was highly significant and 24–57% higher than GCA, indicating the importance of SCA in sugarcane breeding. Currently, most sugarcane breeding programs use genetic and breeding values to select parents (Atkin et al., 2009; Mbuma et al., 2018b, 2020a). The highly significant SCA suggests that GCA alone was inadequate for predicting progeny cane yield and suggests the need for cross appraisal.…”

“…The results showed low R 2 , high CV, and residual variance. These values are characteristic of data from Stage I of sugarcane breeding (Mbuma et al, 2017(Mbuma et al, , 2018a(Mbuma et al, , 2018b(Mbuma et al, , 2020a(Mbuma et al, , 2020b. Trials in Stage I are planted to large numbers of progenies ranging from 25,000 to 50,000.…”

“…Genotypes with high trait values selected for crossing are expected to produce progenies with high trait values, especially when narrow‐sense heritability estimates are moderate to high, which is not really the case in most characters of importance in sugarcane (Wei & Jackson, 2016). In recent years, genotypes with high breeding values (producing progenies with high trait values in family evaluation plots) have been used extensively for crossing (Mbuma, Zhou, & Van Der Merwe, 2018b). There has been limited or indirect exploitation of nonadditive genetic effects or SCA (Jackson, 2019), yet sugarcane is an outcrossing plant similar to maize where high levels of inbreeding depression occurs when plants are self‐pollinated (Ferreira, Barbosa, Castro, Peternelli, & Cruz, 2005) and high levels of heterosis occur when outcrossed (Makumbi, Betran, Banziger, & Ribaut, 2011).…”

General combining ability (GCA) referencing additive genetic effects and specific combining ability (SCA) referencing nonadditive effects have been applied for decades in maize (Zea mays L.) breeding and other crops to produce greater genetic gains in crop breeding. This study examined the magnitude of GCA and SCA for cane yield and evaluated potential for application in sugarcane (Saccharum spp.) breeding. Data were collected from unselected first‐stage breeding populations sourced from the irrigated, midlands (high‐altitude), and coastal breeding programs of the South African Sugarcane Research Institute. Cane yield data calculated from number of stalks, stalk height, and stalk diameter was analyzed using best linear unbiased prediction (BLUP) analysis where female and male effects (GCA) and female × male interaction effects (SCA) were defined as random effects. There were significant (P < .05) female but nonsignificant male effects. Female × male interaction was highly significant (P < .001) and larger than both female and male effects, indicating higher SCA than GCA. Specific combining ability variance was 24% (midlands), 31% (coastal), and 57% (irrigated) higher than GCA. Genotypes with low GCA produced higher SCA. Crosses from parents originating from different breeding backgrounds produced higher SCA than those from the same backgrounds. Crosses with significant SCA produced 24–42% greater cane yield than those with nonsignificant SCA. Using GCA to develop parents with high breeding values and SCA to evaluate parent cross combinations will maximize exploitation of heterosis in sugarcane breeding. The results suggest the possibility to develop heterotic groups that are diverse and complementary as a strategy to optimize utilization of SCA.

“…An excellent sugarcane variety was always selected from hundreds of sugarcane combinations (Yang et al, 2011). High yield, high sucrose content, strong ratoon ability and multi-resistance were the breeding targets (Mbuma et al, 2018;Huang et al, 2016;Zhou et al, 2017). However, the most prominent problem encountered in conventional breeding was the narrow genetic basis and insufficient parental innovation, which greatly affects the selection of new breakthrough sugarcane varieties.…”

In order to observe the performance of lodging-related traits, evaluate the lodging-resistant ability of different combinations of sugarcane, a field experiment was conducted in 2018. Thirty sugarcane combinations were used as the materials, and the lodging grade, fracture resistance force, basal stem diameter, middle stem diameter and brix were investigated. With the data of lodging classification, the lodging resistance index was established. It was found that the lodging resistance index was significantly and positively correlated with the ratio of basal and middle stem diameters and brix. A cluster analysis was conducted, for the thirty sugarcane combinations by the lodging resistance index, which showed sixteen were lodging resistant, thirteen half-lodging, and two complete-lodging.

“…Consequently, sucrose content on a family mean basis has been a highly prioritized selection criteria in the seedling and first line trial stages of our program. Family selection, in the seedling stage, is widely practiced to different extents in several countries including Australia (Cox & Stringer, 1998; Hogarth et al., 1990; Jackson et al., 1995a, 1995b; Kimbeng et al., 2000; Wei et al., 2022), the United States (Chang & Milligan, 1992a, 1992b; Milligan et al., 1990b; Tai et al., 2003), India (Shanthi et al., 2011; Shanthi et al., 2008), Brazil (Ferreira et al., 2022; Muetanene et al., 2023), and South Africa (Mbuma et al., 2018; Mbuma, 2016; Mbuma et al., 2020; Zhou, 2014; Zhou et al., 2013). Sucrose content is customarily used to assess family performance whereas individual seedling or clone selection within families relies on Brix, %, as measured using a hand‐held refractometer (Kimbeng & Cox, 2003).…”

The release of ‘LCP 85‐384’ and its contribution to the Louisiana sugar industry

Basic breeding efforts initiated at the USDA‐ARS in Houma, LA, in the late 1950s allowed Louisiana sugarcane breeders, once again, to cross with the wild germplasm of cultivated sugarcane, Sacharum spontaneum. ‘LCP 85‐384’ was the first success story from this effort and was quickly adopted by growers. It became clear that the cultivar would prove to be substantially impactful to the Louisiana sugar industry. Performing at unprecedented yields in ratoon crops, LCP 85‐384 changed how Louisiana growers would manage their crops. The variety proved to possess traits that fared well in the subtropical production zones of the state. Substantial stalk populations seemed to play a vital role in the necessary ratoon ability and consequent cold tolerance necessary for production in Louisiana. After significant disease pressure, the variety quickly declined in production acreage, but not in impact. It continued to provide sustained progress as a parent for years, contributing to most modern commercial cultivars in Louisiana. Today, LCP 85‐384 and its progeny are used in breeding and genetic research to usher in the next era of progress in the Louisiana sugar industry. Meanwhile, through cooperative efforts of breeding programs around the world, it is making its mark on the sugarcane industries of Argentina in much the same way as it did in Louisiana. In the future, it is expected that the progress made in the breeding program will continue by building upon the gains achieved from LCP 85‐384 and its progeny for the sustained success of the Louisiana sugarcane industry.
