“…Significant genetic variations in mesocotyl elongation, together with bias distribution in rice germplasm populations, were observed in those screening experiments [ 6 , 8 , 10 , 11 , 12 , 16 , 17 , 18 , 36 , 37 ]. Largely different ranges were reported, mainly at the side of high phenotypic values ( Table S4 ).…”

“…Mesocotyl length is a quantitative trait and displays a substantial amount of variation among genotypes. Several previous studies have reported the associated QTLs and candidate genes for rice mesocotyl elongation through linkage analysis or GWAS [ 12 , 15 , 16 , 17 , 18 , 20 , 38 ]. Some known QTL intervals and novel QTLs could be detected through linkage analysis and GWAS in this study ( Table S2 ).…”

“…Wang et al (2021) identified 14 QTLs for mesocotyl elongation via QTL sequencing using 12 F 2 populations, and five unique QTLs with a GWAS using two diverse panels [17]. Gothe et al (2022) also identified eight QTLs for mesocotyl elongation using a GWAS [18]. Several genes were characterized that regulated mesocotyl elongation via different molecular mechanisms, including examples like GY1 [19], OsGSK2 [20], OsPAO5 [21], and OsSMAX1 [22].…”

Mesocotyl elongation of rice seedlings is a key trait for deep sowing tolerance and well seedling establishment in dry direct sowing rice (DDSR) production. Subsets of the Rice Diversity Panel 1 (RDP1, 294 accessions) and Hanyou 73 (HY73) recombinant inbred line (RIL) population (312 lines) were screened for mesocotyl length (ML) via dark germination. Six RDP1 accessions (Phudugey, Kasalath, CA902B21, Surjamkuhi, Djimoron, and Goria) had an ML longer than 10 cm, with the other 19 accessions being over 4 cm. A GWAS in RDP1 detected 118 associated SNPs on all 12 chromosomes using a threshold of FDR-adjusted p < 0.05, including 11 SNPs on chromosomes 1, 4, 5, 7, 10, and 12 declared by −log10(P) > 5.868 as the Bonferroni-corrected threshold. Using phenotypic data of three successive trials and a high-density bin map from resequencing genotypic data, four to six QTLs were detected on chromosomes 1, 2, 5, 6, and 10, including three loci repeatedly mapped for ML from two or three replicated trials. Candidate genes were predicted from the chromosomal regions covered by the associated LD blocks and the confidence intervals (CIs) of QTLs and partially validated by the dynamic RNA-seq data in the mesocotyl along different periods of light exposure. Potential strategies of donor parent selection for seedling establishment in DDSR breeding were discussed.

“…Red rice contains many phenolic compounds ranging from simple phenolic compounds to complex compounds that bind to glucose groups as glycons. One group of phenolic compounds that have benefits as antioxidants is a group of flavonoid compounds (Beerelli et al, 2019;Gothe et al, 2022). The group of flavonoid compounds such as anthocyanins (a glycon form of anthocyanidins) is a group of natural ingredients in plants that act as antioxidants.…”

The effect of the nutritional value of red rice tape is mainly different in fiber and antioxidant content, with sticky rice tape as a new health food innovation. The purpose of this study was to make a tape food by comparing glutinous rice with brown rice to the volume of brewed brem and the organoleptic test of tape food. This study used 3 designs: an accurate experimental study for the treatment of red rice tape on the volume of brem drinks; an experimental quasi for measuring organoleptic and hedonic test scores; and a pre-experiment for the number of panelists. Collecting data from the volume of brem drinks and organoleptic and hedonic tests. Analysis of the volume of brem drinks due to treatment using ANOVA and if there is a significant difference analyzed by LSD test using post hoc test. Organoleptic and hedonic tests were performed to determine the score of each organoleptic and hedonic test by the panelists. The ANOVA analysis of the production volume of Brem drinks from the three treatments showed significant differences. The results of the LSD test showed that the variation of the ratio of glutinous rice: to brown rice 3:1 was significantly different in the 1:1 treatment and the 1:3 treatment. The treatment of the ratio of glutinous rice: brown rice 1: 1 was not significantly different from the comparison treatment of glutinous rice: brown rice 1:3. Organoleptic and hedonic tests, as well as characteristics produced from red rice tape, were evaluated by organoleptic and hedonic test scores.
