“…They also suggested that the nutritional quality of red rice was comparable to many millets, fruits and vegetables. Pathak et al, (2017) also reported that pigmented rice had higher amount of protein content than non-pigmented rice, similar to the findings of the present study. Among the black pericarp genotypes, BPT 3140 (10.35%) recorded minimum protein content, while Kakirekalu recorded maximum protein content (13.50%).…”

The present investigation was undertaken with 33 coloured and white rice genotypes to identify promising slender grain genotypes with high yield and good nutrition quality. The study involved seven red pericarp, eight black pericarp and 17 white rice genotypes, in addition to the check, BPT 5204. The results revealed black pericarp genotypes to be in general, high yielding with intermediate amylose content, high phenol, protein, zinc and iron content, compared to the red pericarp and white rice genotypes studied in the present investigation. The red pericarp genotypes were in general noticed to be early with high antioxidant activity, compared to the black pericarp and white rice genotypes. The white rice genotypes, however, recorded higher head rice recovery per cent, compared to the red and black pericarp genotypes. Further, the red pericarp genotype, BPT 3178; black pericarp genotype, BPT 2848; and the white rice genotypes, BPT 2615, BPT 2782 and MTU 1281 were identified to be promising high yielding and nutritionally rich rice genotypes, compared to BPT 5204.

“…In white rice group, the culture 13-5 had similar and near to zinc content for with kavuni parent. The zinc content of the rice lines as recorded in the present study was found to be similar with the findings of Pathak et al, 2017 [22]. Phenotypic correlation coefficient among physical characters of 25 rice samples has given in Table 4.…”

The objective of the study was determining the physical properties and minerals composition in the twenty three breeding lines and two parent rice varieties. Physical properties found that no significant difference in terms of shape and size of the grain. The calcium, iron and zinc content of rice samples in the ranged from 7.56 to12.72 mg/100g, 0.73 to 2 mg/100g and 2.29 to 3.39 mg/100g, respectively. Results showed that the cultures 144-5 (12.72 mg/100g)>155-3(12.62 mg/100g)>144-2(12.61 mg/100g) =148-2 (12.61 mg/100g) contained higher levels of calcium content. Among the rice lines accessions, the samples: 144-2 (2.04 mg/100g)>32-2 (2 mg/100g)>145-2 (1.67 mg/100g)>145-3 (1.57mg/100g) had higher contents of iron. The zinc content of rice lines ranked in the following decreasing order; 144, 144-1,144-2, 144-3, 145-3, 145-6, 143-1,148-2,271-2. From the twenty three rice lines, some of the rice lines contained more minerals than of parent kavuni. The finding indicated that the cross breeding technique may increases not only the yield and also nutrient content of rice.

“…This germplasm can be a good source of valuable genes/quantitative trait locis (QTLs) for various nutrition, grain quality, and pest and disease resistance traits for rice breeding programs [4,26,27,28,29,30,31]. Several studies on the characterization of colored rice for different antioxidant compounds, vitamins, and minerals have shown wide variations and these accessions were found to have 3- to 4-fold higher nutrient content than modern rice varieties [32,33,34,35]. Similarly, the natural variation for bacterial leaf blight (BLB) resistance in the colored rice can be used for breeding BLB resistance in rice.…”

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.
