“…This result was in agreement with the studies conducted by Visscher et al (1996) and Frisch et al (1999) [135,136]. In addition, Singh et al (2021) studied the introgression of favorable alleles of crtRB1 and lcyE genes into opaque2 (o2)-based four inbreds, namely, QLM11, QLM12, QLM13, and QLM14 using marker-assisted backcross breeding [137]. Awata et al (2021) used marker-assisted backcross (MABC) and doubled haploid (DH) methods to transfer genes for resistance to maize lethal necrosis (MLN).…”

“…In fact, as Liebermann [136] puts it, "many researchers [137] thus consider Homo sapiens to be a morphologically diverse species with archaic and anatomically modern grades." And, in his 2019 article, Caldararo argues that no amount of mathematical jiggling can demonstrate a clear separation between the Upper Paleolithic premodern populations and present-day humans.…”

“…These heterotic groups (HGs) are composed of parental inbred lines that exhibit complementary genetic backgrounds, resulting in the expression of heterosis when crossed to opposite HGs (J. Singh et al, 2021). To develop these HGs, various methods have been employed in maize breeding programs.…”

Maize (Zea mays L.) is a versatile crop with high genetic yield potential and various uses. While yellow maize is primarily used for animal feed, white maize is preferred as a food by rural and tribal populations in India. However, white maize landraces suffer immensely in terms of low yield. Heterotic grouping is an excellent method to develop hybrids with increased yield potential in maize. The heterotic grouping of 78 white maize inbred lines was performed using combining ability and molecular diversity analysis. The lines were crossed with two testers, and the resulting hybrids were evaluated for grain yield at three locations representing different agroecological zones in India. The combining ability analysis based on specific combining ability effects on mean grain yield was used to classify the inbred lines into heterotic groups (HG‐A: 18 inbreds; HG‐B: 33 inbreds). Additionally, marker‐based clustering using 62,470 single nucleotide polymorphisms (SNPs) generated through genotyping by sequencing was also employed to determine the genetic relationships among these lines. The combining ability information was superimposed on marker‐based clustering data to obtain the heterotic grouping information, and two distinct HGs with 7 (HG‐1) and 18 inbred lines (HG‐2) were developed. The results of this study will contribute to the development of high‐performing white maize hybrids through the efficient utilization of clear‐cut and well‐defined HGs. Hence, the use of SNP markers along with the combining ability of inbred lines is a useful method for heterotic grouping and understanding of genetic relationships of white maize.

“…Marker-assisted breeding with Meta-analysis is a powerful strategy for the identification of quantitative trait loci with a gene of interest for introgressive biofortification in maize because conventional breeding is a long-run approach, agronomic fortification like micro-organism-based inoculation to rich the desired level of nutrients from the beginning isn't a sustainable type, and transgenic fortification is more controversial and costly due to the diverse germplasm of maize [ 33 , 34 , 35 ]. Microorganism-based inoculum on seed or soil with techniques called 16S rRNA sequencing was used to identify Bacillus sp.…”
