“…Waxy maize starch granules are polygonal and has the highest crystallinity and largest proportion of double helix components and ordered structure in external region among various maize starches ( Yu et al, 2015 ). Consumers prefer waxy maize with a sweet flavor, high stickiness, and soft texture ( Ramekar, Sa, Park, Park, & Lee, 2020 ). Combinations of wx and other genes may alter grain quality ( Wang et al, 2019 ).…”

“…Due to a natural genetic mutant of waxy genes, the endosperm starch of waxy maize comprises nearly 100% amylopectin, resulting in the stickiness of its kernels (Gu et al 2020). Because of its excellent quality, rich nutrition, unique flavor, and sticky texture, waxy maize is widely consumed as a fresh food in some Asian countries (Hossain et al 2019, Ramekar et al 2020. Similar to sweet maize, ears of waxy maize was directly harvested and consumed at the milk stage, thereby good ear appearance, superior flavor, and high yield are the top priorities in breeding programs (Hossain et al 2019, Wu et al 2019.…”

Ear tip-barrenness (ETB), which results from aborted kernels or infertile florets at the ear tip, is an undesirable factor affecting the yield and quality of waxy maize. To uncover the genetic basis of ETB, a genomewide association study (GWAS) was conducted using the genotype with 27,354 SNPs and phenotype with three environments. Five SNPs that distributed on chromosomes 1, 3 and 6, were identified to be significantly associated with ETB based on the threshold of false discovery rate (FDR) at 0.05. Among these significant loci, three SNPs were clustered together and colocalized with genomic regions previously reported. The average length of ETB decreased almost linearly from the inbred lines containing no favorable alleles across the three loci (1.75 cm) to those with one (1.18 cm), two (0.94 cm) and three (0.65 cm) favorable alleles. Moreover, three important genes, Zm00001d030028, Zm00001d041510 and Zm00001d038676 were predicted for three significant QTLs, respectively. These results promote the understanding genetic basis for ETB and will be useful for breeding waxy maize varieties with high-quality and high-yield.
