“…In sugarcane (Saccharum spp. ), research on combining ability was conducted in Australia (Hogarth, Wu, & Heinz, 1981), Brazil (Bressiani, Burnquist, Fuzatto, Bonato, & Geraldi, 2002;Carvalho, Gezan, Peternelli, & Barbosa, 2014; Santana, Reis, & Chaves, 2017;Silva, Landell, Goncalves, Bressiani, & Campana, 2002), India (Alarmelu, Hemaprabha, Nagarajan, & Shanthi, 2010;Durai & Hemaprabha, 2016), and the United States (Miller, 1977;Wu, Heinz, Meyer, & Ladd, 1980). Sugarcane breeding has always directly exploited additive genetic effects associated with GCA during parent selection and crossing (Wei et al, 2017).…”

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.

“…A high estimate of SCA indicates that the parents present in a cross combination have good allelic complementarity (Santana, Reis, & Chaves, 2017), especially because they present divergence or because they do not show high kinship. Additionally, SCA estimates could be considered as measures of the distance between parents, that is, the SCA matrix represents the distance matrix between parents.…”

“…This was the first effort to identify heterotic groups in sugarcane and thus make it possible to more effectively explore the nonadditive and additive effects involved in the expression of traits of importance to the crop (Figure 1). Recognizing the importance of exploring both SCA and GCA (Barbosa et al, 2004;Bastos et al, 2003;Bressiani et al, 2002;Hogarth, 1980;Santana, Reis, & Chaves, 2017;Wu et al, 1980), we propose the application of RRS in sug-arcane breeding. In this context, RRS using the population in question could be applied at two levels, as described by Resende and Barbosa (2005): (a) at the population level, involving the crossing of several individuals from one population with individuals from the reciprocal population, and (b) at the individual level (IRRS), involving only one individual from each population, which results in an excellent cross with high genotypic value and high SCA.…”

Establishment of gene pools for systematic heterosis exploitation in sugarcane breeding

In sugarcane (Saccharum spp) breeding, despite the potential use of reciprocal recurrent selection (RRS) to explore both nonadditive and additive effects for economic value traits, to date, no publications have targeted obtaining heterotic groups to support this selection strategy. The aim of this study was to (a) to identify sugarcane gene pools to effectively explore nonadditive and additive genetic effects via reciprocal recurrent selection, (b) estimate genetic parameters, and (c) select parents and cross combinations. Seventy-nine sugarcane families were obtained from crossing 38 parents in a crossing scheme known as disconnected factorial design. The families were evaluated in randomized complete block design with five replicates. The statistical genetic analysis was performed with linear mixed models through restricted maximum likelihood/best linear unbiased predictor. The results revealed that nonadditive effects were predominant in explaining genetic variation for cane yield (t ha −1), pol yield (t ha −1), and fiber yield (t ha −1). For brix, fiber and corrected Pol (PCC) traits, additive effects were predominant. Estimates of specific combining ability and pedigree information allowed the establishment of gene pools for systematic heterosis exploitation through RRS breeding efforts. The prediction of the additive genetic values of parents for selection based on the progeny's behavior obtained via disconnected factorial design is an alternative that should be used in sugarcane breeding programs.

“…Selection for borer resistance at the T1 stage could increase the frequency of favorable alleles, increasing the resistance of the population for the following selection stages. Individual (mass) selection is inefficient at this stage for traits with low heritability, such as borer resistance, due to the lack of replication for individual genotypes (Santana et al 2017). Family selection is particularly useful for traits with low heritability because, unlike clones, families can be evaluated using replicated plots and across years and sites, thereby improving estimates of family means (Kimbeng and Cox 2003).…”

“…Family selection, when followed by individual clone selection, is superior in terms of genetic gain than either family or individual clone selection alone (Brasileiro et al 2016). The availability of family data makes it possible to estimate the breeding value of parents using the Best Linear Unbiased Predictors (BLUP), and it enables planning for better cross combinations (Santana et al 2017). The BLUP allows data from a diverse range of mating designs and parent, family, and individual data to be combined into a single breeding value for each trait and genotype (Kimbeng andCox 2003, Barbosa et al 2004).…”

A T1 (sugarcane population originating from true seeds) and T2 (first sugarcane clonal stage) population were used to estimate genetic parameters and compare selection strategies for Diatraea saccharalis (Lepidoptera: Crambidae) resistance in sugarcane. In the T1 stage, heritability at the family mean level (h²=0.77) was higher than individual genotype heritability (h²=0.16), and the additive genetic effect was more important for sugarcane borer resistance than non-additive effects. In addition, there was high genotypic variance among and within full-sib families. In the T2 population, genotypic variance was high, and heritability at the clone mean level was moderate (h²=0.61). We can conclude that family experiments enable selection of more promising families and parents for borer resistance. However, due to high genotypic variance within families, family selection at the T1 stage must be followed by clone selection at the T2 stage.
