Bounteous modern and innovative biotechnological tools have resulted in progressive development in the barley breeding program. Doubled haploids developed (homozygous lines) in a single generation is significant. Since the first discovery of haploid plants in 1920 and, in particular, after discovering androgenesis in 1964 by Guha and Maheshwari, the doubled haploidy techniques have been progressively developed and constantly improved.

Buckwheat is a crop that has gained considerable interest worldwide due to its nutritional, economical, and pharmaceutical values. To ensure food and nutritional security in a scenario of global climate change, this pseudocereal is a competent alternative to staple crops. With rising knowledge regarding the nutraceutical potential, the popularity of this species is expected to increase further in coming years.

The value of exotic wheat genetic resources for accelerating grain yield gains is largely unproven and unrealized. We used next-generation sequencing, together with multi-environment phenotyping, to study the contribution of exotic genomes to 984 three-way-cross-derived (exotic/elite1//elite2) pre-breeding lines (PBLs). Genomic characterization of these lines with haplotype map-based and SNP marker approaches revealed exotic specific imprints of 16.

Article Synopsis
  • Haploid induction in wheat can be efficiently achieved by crossing it with pollen from Imperata cylindrica, facilitating doubled haploid breeding.
  • Cytological studies revealed that while wheat gametes successfully fertilized, the I. cylindrica chromosomes were completely eliminated during the zygote's first cell division.
  • The inability of I. cylindrica chromosomes to align and segregate properly during metaphase and anaphase suggests that they lack functional kinetochores, leading to their removal from the daughter nuclei.
