High amylopectin in waxy maize synergistically affects seed germination and seedling vigour over traditional maize genotypes
Waxy maize grains rich in amylopectin have emerged as a popular food and industrial raw materials. Here, a set of waxy inbreds having recessive waxy1 (wx1) gene derived through marker-assisted selection (MAS), an...

Analysis of nutritional composition in opaque2- and crtRB1-based single- and double-biofortified super sweet corn
Sweet corn has emerged as a favorite food item worldwide owing to its kernel sweetness. However, traditional sweet corn cultivars are poor in provitamin-A (proA) and essential amino acids, viz., lysine and try...

Assessing sequence variation, haplotype analysis and molecular characterisation of aspartate kinase2 (ask2) gene regulating methionine biosynthesis in diverse maize inbreds
Traditional maize grain is deficient in methionine, an essential amino acid required for proper growth and development in humans and poultry birds. Thus, development of high methionine maize (HMM) assumes grea...

Enhancement of nutritional quality in maize kernel through marker-assisted breeding for vte4, crtRB1, and opaque2 genes
Traditional maize is poor in vitamin-E [α-tocopherol (α-T): 6–8 ppm], vitamin-A [provitamin-A (proA): 1–2ppm], lysine (0.150–0.2–50%), and tryptophan (0.030–0.040%). Here, we combined favourable alleles of vte4,

Development of novel gene-based markers for waxy1 gene and their validation for exploitation in molecular breeding for enhancement of amylopectin in maize
Waxy corn possessing high amylopectin is widely employed as an industrial product. Traditional corn contains ~ 70–75% amylopectin, whereas waxy corn with the mutant waxy1 (wx1) gene possesses ~ 95–100% amylopecti...

Characterization of crtRB1- and vte4-based biofortified sweet corn inbreds for seed vigour and physico-biochemical traits
Sweet corn possessing recessive shrunken2 (sh2) gene is popular worldwide. Traditional sweet corn is poor in vitamin A and vitamin E. Plant breeders during the selection of sweet corn genotypes mainly emphasize o...

Allelic variation in sugary1 gene affecting kernel sweetness among diverse-mutant and -wild-type maize inbreds
Sweet corn is popular worldwide as vegetable. Though large numbers of sugary1 (su1)-based sweet corn germplasm are available, allelic diversity in su1 gene encoding SU1 isoamylase among diverse maize inbreds has ...

Development of multinutrient-rich biofortified sweet corn hybrids through genomics-assisted selection of shrunken2, opaque2, lcyE and crtRB1 genes
Sweet corn has gained worldwide popularity. Traditional sweet corn possesses low concentration of essential nutrients such as lysine (0.15–0.25%), tryptophan (0.03–0.04%) and provitamin-A (proA 3–4 ppm), and d...

Low expression of carotenoids cleavage dioxygenase 1 (ccd1) gene improves the retention of provitamin-A in maize grains during storage
Provitamin-A (proA) is essentially required for vision in humans but its deficiency affects children and pregnant women especially in the develo** world. Biofortified maize rich in proA provides new opportun...

Marker-assisted introgression of opaque2 allele for rapid conversion of elite hybrids into quality protein maize
Maize is a valuable source of food and feed worldwide. Maize endosperm protein is, however nutritionally poor due to the reduced levels of two essential amino acids, lysine and tryptophan. In this study, reces...
