To achieve the food and energy security of an increasing World population likely to exceed nine billion by 2050 represents a major challenge for plant breeding. Our ability measure traits under field conditions has improved little over last decades currently constitutes bottleneck in crop improvement. This work describes development tractor-pulled multi-sensor phenotyping platform small grain cereals with focus on technological system. Various optical sensors like light curtain imaging, 3D...
Significance Selfing species wheat are bred as pure-line varieties with stagnating yield growths. In contrast, selection gain in maize is high, owing to massive investment sustained by hybrid seed sales, coupled an efficient exploitation of vigor. We have developed a three-step strategy for establishing heterotic pattern, which was one the central unsolved challenges initiating breeding programs. The benefits our approach demonstrated using data wheat, but relevant several autogamous crops....
Abstract Postembryonic organ formation in higher plants relies on the activity of stem cell niches shoot and root meristems where differentiation resident cells is repressed by signals from surrounding cells. We searched for mutations affecting maintenance isolated semidominant l28 mutant, which displays premature termination meristem Allele competition experiments suggest that a dominant-negative allele APETALA2 (AP2) gene, previously has been implicated floral patterning seed development....
Increases in the yield of wheat during Green Revolution late 20th century were achieved through introduction Reduced height (Rht) dwarfing genes. The Rht-B1 and Rht-D1 loci ensured short stature by limiting response to growth-promoting hormone gibberellin, are now widespread international breeding programs. Despite this advantage, interference with plant's gibberellin also triggers adverse effects for a range important agronomic traits, consequently modern genes urgently required. In study,...
Abstract Key message A simple and rapid speed breeding system was developed for short-day crops that enables up to five generations per year using LED lighting systems allow very specific adjustments regarding light intensity quality. Plant is a key element future agricultural production needs cope with growing human population climate change. However, the process of developing suitable cultivars time-consuming, not least because long generation times crops. Recently, has been introduced...
Abstract Background Triticale is adapted to a wide range of abiotic stress conditions, an important high-quality feed stock and produces similar grain yield but more biomass compared other crops. Modern genomic approaches aimed at enhancing breeding progress in cereals require genetic linkage maps. Consensus maps are that created by joint analysis the data from several segregating populations different available for their construction. The phenomenon alleles locus deviate Mendelian...
Genomic selection exploits dense genome-wide marker data to predict breeding values. In this study we used a large sugar beet population of 924 lines representing different germplasm types present in populations: unselected segregating families and diverse from more advanced stages selection. All have been intensively phenotyped multi-location field trials for six agronomically important traits genotyped with 677 SNP markers. We ridge regression best linear unbiased prediction combination...
Copy number variation was found to be a frequent type of DNA polymorphism in the human genome often associated with diseases but its importance crops and effects on agronomic traits are still largely unknown.Here, we employed large worldwide panel 1110 winter wheat varieties assess frequency geographic distribution copy variants at Photoperiod-B1 (Ppd-B1) Vernalization-A1 (Vrn-A1) loci as well their flowering time under field conditions. We identified novel four variant Vrn-A1 based...
ABSTRACT Einkorn ( Triticum monococcum L.), emmer T. dicoccum and spelt spelta L.) are old‐world hulled wheat crops currently receiving renewed interest of consumers, bakers, millers, farmers. Our objectives were to (i) compare einkorn, emmer, with bread aestivum durum regarding their main agronomic quality traits, (ii) elaborate the heritability correlation among these traits across species, (iii) draw conclusions about optimized farming processing practices for spelt. For this purpose,...
The needs of a growing human population require rapid and efficient development improved cultivars by plant breeders. doubled haploid (DH) technology enables generating completely homozygous lines in single step and, thus, is central to modern genetics breeding approaches. Rapid reliable identification seeds with embryo after vivo induction elementary the method utilized maize but current systems have severe shortcomings preventing their use many germplasm types. Here, we describe an...
To extend agricultural productivity by knowledge-based breeding and tailor varieties adapted to specific environmental conditions, it is imperative improve our ability assess the dynamic changes of phenome crops under field conditions. this end, we have developed a precision phenotyping platform that combines various sensors for non-invasive, high-throughput high-dimensional small grain cereals. This yielded high prediction accuracies heritabilities biomass triticale. Genetic variation...
Abstract Predicting single‐cross performance is of high importance to improve the efficiency sunflower ( H elianthus annuus L .) hybrid breeding programmes. We used experimental data from inter‐ and intragroup hybrids their parental lines adapted C entral E urope (i) study genetic diversity combining ability (ii) examine accuracy predict based on phenotypic genomic data. evaluated 133 104 intergroup with in replicated trials at four environments for grain yield, oil yield content....
