“…Thus, breeders tend to select superior cultivars based on highly heritable traits such as FC as indicated in this study, whose broad sense heritability was relatively high (77%-85%) in accordance with several other previous studies (Islam et al, 2018;Wenworn et al, 2013).…”

“…The FC values in the S 1 progenies of 'LCP 85-384' (15.28%-23.78%) were comparatively higher than the FC of usual commercial sugarcane hybrids (Islam et al, 2018;Wenworn et al, 2013 clone US56-15-8, a S. spontaneum, as well as a S. barberi clone, in its pedigree (Milligan et al, 1994).…”

“…However, as a highly polyploid and outcrossing heterozygous species, sugarcane requires a large number of markers to guarantee sensible coverage of its large genome (Garcia et al, 2006(Garcia et al, , 2013Wang et al, 2010). Later, Liu et al (2016) Several FC-associated QTL studies have been reported in sugarcane, however, most of the QTL are packed with sugar and yield related traits (Balsalobre et al, 2017;Islam et al, 2018;Ming et al, 2002;Pastina et al, 2012). At first, 36 QTL related to sucrose content and 102 QTL associated with six agronomic traits (sugar yield, POL, stalk weight, stalk number, FC and ash content) were identified using two interspecific Saccharum F 1 populations (Ming et al, 2001(Ming et al, , 2002.…”

“…Balsalobre et al (2017) constructed 223 linkage groups (LGs) with 934 GBS-based markers and 59 SSR markers, they identified one QTL associated with FC along with six QTL associated with other agronomic traits. Islam et al (2018) identified 45 QTL associated with several sugar and yield related traits, out of which six QTL controlling FC and accounting for 68.67% phenotypic variation.…”

The fibre content (FC) of sugarcane millable stalks is important for both sugar and bioenergy production. Higher FC favours the energy producer while lower FC facilitates the efficient sugar extraction. A molecular marker for FC helps select improved sugarcane cultivars with favourable partitioning of FC for both sugar and energy production industries. A quantitative trait loci (QTL) study was conducted using an enriched linkage map of LCP 85-384 and FC data from two crop cycles (plant cane and first ratoon) of its self-progeny population. A total of five unique QTL were identified across both crop cycles and combined, of which three QTL (qFC020, qFC044 and qFC053) were common explained a total of 22.46%, 23.93% and 25.14% of the phenotypic variances for plant cane, first ratoon and combined data, respectively. As FC values increased gradually, the QTL allele combination effect also increased. Using markers linked to these putative common QTL alleles would benefit the breeders to select sugarcane lines for sugar and bioenergy production.

“…For the sugar content (Brix), two (2P5849859 and 2P65250224) out of three associated markers were found at a distance of 333.1 and 1631.3 kbp, respectively, from the associated gene (Sb02g004780 and Sb02g028450) identified previously (Racedo et al, 2016). Recently, quantitative trait locus mapping has been conducted in a biparental population of 173 progeny with multiple quantitative trait loci detected for Brix, water content and stalk diameter (Islam et al, 2018). We had associated markers with distances of 1615.6, 6556.7, 3165.5, and 591.1 kbp from their closest markers (3SNP463 for stalk diameter, 2SNP3040 for Brix, and 1SNPUN315 and 3SNP3118 for water content), respectively.…”

Sugarcane (Saccharum spp.) is an important economic crop, contributing up to 80% of sugar and approximately 60% of biofuel globally. To meet the increased demand for sugar and biofuel supplies, it is critical to breed sugarcane cultivars with robust performance in yield traits. Therefore, dissection of causal DNA sequence variants is of great importance, as it provides genetic resources and fundamental information for crop improvement. In this study, we analyzed nine yield traits in a sugarcane diversity panel consisting of 308 accessions primarily selected from the World Collection of Sugarcane and Related Grasses. By genotyping the diversity panel via target enrichment sequencing, we identified a large number of sequence variants. Genome-wide association studies between the markers and traits were conducted, taking dosages and gene actions into consideration. In total, 217 nonredundant markers and 225 candidate genes were identified to be significantly associated with the yield traits, which can serve as a comprehensive genetic resource database for future gene identification, characterization, and selection for sugarcane improvement. We further investigated runs of homozygosity (ROH) in the sugarcane diversity panel. We characterized 282 ROHs and found that the occurrence of ROHs in the genome were nonrandom and probably under selection. The ROHs were associated with total weight and dry weight, and high ROHs resulted in a decrease in the two traits. This study suggests that genomic inbreeding has led to negative impacts on sugarcane yield.
