salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

This study was aimed at obtaining information on the effects of G × E interaction yield among doubled haploid lines (DH) lowland rice and to obtain stable high yielding lines. The experiment conducted in 9 environments (E), namely Indramayu (2018), Subang Malang I II (2019), Blitar Cianjur Lombok Bali Madiun (2019). A randomized complete block design with 3 replications used each location. geno...

Doubled haploid (DH) technology, which is used for rapidly purifying genetic resources, is a key technology in modern maize breeding. The present study evaluated the tissue culture characteristics of maize haploid coleoptile sections, in order to provide a new way of haploid doubling. With 20 combinations of haploid coleoptile sections, obtained by hybridization within Reid, Tangsipingtou, and ...

Next-generation sequencing enables genome-wide genotyping of a large population and further facilitates the construction of a genetic linkage map. Low-coverage whole-genome sequencing has been employed for genetic linkage map construction in several species. However, this strategy generally requires available high-quality reference genomes and/or designed inbred pedigree lines, which restrict t...

Haploids are plants (sporophytes) that contain a gametic chromosome number (n). They can originate spontaneously in nature or as a result of various induction techniques. Spontaneous development of haploid plants has been known since 1922, when Blakeslee first described this phenomenon in Datura stramonium (Blakeslee et al., 1922); this was subsequently followed by similar reports in tobacco (N...

Androgenesis in vitro is a basic method of obtaining haploid plants and DH (doubled haploid) lines major crops such as potato, rapeseed, tomato, pepper, wheat, maize, barley, also many different minor species with lower agricultural impact. Diploid appearing among androgenic regenerants are the effect spontaneous doubling chromosome number cells during an embryo’s early developmental stages val...
