“…Additionally, the co-localization of a QTL for both anthocyanin and proanthocyanin content (LG 3, position 59 cM) is expected given that these two compounds are produced within the same biochemical pathway, and are dependent on each other. Mapping studies comparing the location of anthocyanin and proanthocyanidin-related QTL are limited; however, a recent study in red rice found at least two collocated QTLs for anthocyanin content and proanthocyanins (Xu et al 2017). Using the locations of QTL for anthocyanin content, we attempted to identify candidate genes; however, our search was limited by the highly fragmented cranberry genome available.…”

Because of its known phytochemical activity and benefits for human health, American cranberry (Vaccinium macrocarpon L.) production and commercialization around the world has gained importance in recent years. Flavonoid compounds as well as the balance of sugars and acids are key quality characteristics of fresh and processed cranberry products. In this study, we identified novel QTL that influence total anthocyanin content (TAcy), titratable acidity (TA), proanthocyanidin content (PAC), Brix, and mean fruit weight (MFW) in cranberry fruits. Using repeated measurements over the fruit ripening period, different QTLs were identified at specific time points that coincide with known chemical changes during fruit development and maturation. Some genetic regions appear to be regulating more than one trait. In addition, we demonstrate the utility of digital imaging as a reliable, inexpensive and high-throughput strategy for the quantification of anthocyanin content in cranberry fruits. Using this imaging approach, we identified a set of QTLs across three different breeding populations which collocated with anthocyanin QTL identified using wet-lab approaches. We demonstrate the use of a high-throughput, reliable and highly accessible imaging strategy for predicting anthocyanin content based on cranberry fruit color, which could have a large impact for both industry and cranberry research.

“…Similarly, in a panel of landraces, loci were detected for pericarp color on chromosomes 2, 7, and 8 [38]. A total of 21 QTLs were detected for proanthocyanin and anthocyanin pigments in a recombinant inbred iines RIL population [39]. Similarly, for grain Zn, several major-effect and consistent QTLs have been reported [33,40,41].…”

Colored rice is rich in nutrition and also a good source of valuable genes/quantitative trait loci (QTL) for nutrition, grain quality, and pest and disease resistance traits for use in rice breeding. Genome-wide association analysis using high-density single nucleotide polymorphism (SNP) is useful in precisely detecting QTLs and genes. We carried out genome-wide association analysis in 152 colored rice accessions, using 22,112 SNPs to map QTLs for nutritional, agronomic, and bacterial leaf blight (BLB) resistance traits. Wide variations and normal frequency distributions were observed for most of the traits except anthocyanin content and BLB resistance. The structural and principal component analysis revealed two subgroups. The linkage disequilibrium (LD) analysis showed 74.3% of the marker pairs in complete LD, with an average LD distance of 1000 kb and, interestingly, 36% of the LD pairs were less than 5 Kb, indicating high recombination in the panel. In total, 57 QTLs were identified for ten traits at p < 0.0001, and the phenotypic variance explained (PVE) by these QTLs varied from 9% to 18%. Interestingly, 30 (53%) QTLs were co-located with known or functionally-related genes. Some of the important candidate genes for grain Zinc (Zn) and BLB resistance were OsHMA9, OsMAPK6, OsNRAMP7, OsMADS13, and OsZFP252, and Xa1, Xa3, xa5, xa13 and xa26, respectively. Red rice genotype, Sayllebon, which is high in both Zn and anthocyanin content, could be a valuable material for a breeding program for nutritious rice. Overall, the QTLs identified in our study can be used for QTL pyramiding as well as genomic selection. Some of the novel QTLs can be further validated by fine mapping and functional characterization. The results show that pigmented rice is a valuable resource for mineral elements and antioxidant compounds; it can also provide novel alleles for disease resistance as well as for yield component traits. Therefore, large opportunities exist to further explore and exploit more colored rice accessions for use in breeding.

“…Anthocyanins and proanthocyanidins present in red rice are important nutrients for functional food. In red rice, anthocyanins and proanthocyanidins have been mapped using QTL for marker assisted selection of genotypes for crop improvement with respect to these traits (Xu et al, 2017).…”

Red rice or Laal Dhaan (Oryza sativa L.) is a famous land race of mid and high hills of South Western Himalayas in Himachal Pradesh, Jammu & Kashmir and some parts of Uttrakhand. Being a traditional crop of Himachal Pradesh, red rice is deeply knitted with traditional rituals and used in various folk dishes and snacks. The key special uses include; Phooli Moorhi, Sookhi Moorhi, Chewrhior Hari Moorhi, Shakli or Sanse and the flour of red rice is also used to make Sidhku. Red rice is also used for making beverages in many areas of the state. Lugrhi, a brewed drink prepared from red rice, is famous in Kullu district. The husk separated while making Chewrhi is used as medicine to cure poisoning symptoms in cattle. The decoction made from red rice and lassi is used to cure dysentery in human beings. The rice water separated after cooking rice is fed to pregnant and lactating women as nutritional food supplement. The demand of nutraceutically rich food is increasing day by day. Keeping in view, the increased demand and shrinking area under the red rice, a concrete policy and marketing strategy is urgently required to motivate farmers and boost the cultivation of rice in its traditional areas of cultivation. A well-developed postharvest value chain is urgently required so that this nutraceutically rich gift of nature reaches the consumer across the globe.
