Breeding and genetic aspects of creating productive forms of fast-developing spring bread wheat

open access: yesТруды по прикладной ботанике, генетике и селекции, 2019
Background. In Russia, wheat breeding should also focus on creation of earlier-maturing varieties with an optimal duration of the vegetation period reflecting territorial environmental features.

Identification of QTLs associated with grain-filling duration and heading date in wheat [PDF]

open access: yesBrazilian Journal of Biology
An increase in genetic diversity of bread wheat caused by spring x winter forms leads to an alteration of genetic control of maturity time. Maturity time (MAT) is one of major yield components in wheat, which has two components: the heading date (HD) and

An Accurate Heading Solution using MEMS-based Gyroscope and Magnetometer Integrated System (Preliminary Results) [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
An accurate heading solution is required for many applications and it can be achieved by high grade (high cost) gyroscopes (gyros) which may not be suitable for such applications.

Analysis of VRN1 gene in triticale and common wheat genetic background

open access: yesScientia Agricola, 2014
In cereals, the transition from the vegetative stage to flowering is controlled in the main by the set of vernalization genes. Within these genes the most important role is played by VRN1, which encodes a MADS-box transcription factor, regulating the ...

Genetic Factors Associated with Heading Responses Revealed by Field Evaluation of 274 Barley Accessions for 20 Seasons

open access: yesiScience, 2020
Summary: Heading time is a key trait in cereals affecting the maturation period for optimal grain filling before harvest. Here, we aimed to understand the factors controlling heading time in barley (Hordeum vulgare).

A practical method for implementing an attitude and heading reference system [PDF]

open access: yes, 2014
This paper describes a practical and reliable algorithm for implementing an Attitude and Heading Reference System (AHRS). This kind of system is essential for real time vehicle navigation, guidance and control applications. When low cost sensors are used,

The Effect of Ambient Temperature on Brachypodium distachyon Development

open access: yesFrontiers in Plant Science, 2019
Due to climate change, the effect of temperature on crops has become a global concern. It has been reported that minor changes in temperature can cause large decreases in crop yield.

Correlations of heading time, chlorophyll content and grain yield in a wheat collection [PDF]

open access: yes, 2021
Heading time significantly contributes to wheat adaptability and yield allowing drought escape during the critical developmental stages. Besides, chlorophyll content has been used to assess the level of drought stress and to predict yield.

Real-time Heading Estimation using Perspective Features [PDF]

open access: yes, 2013
There are a large number of commercially available quad-rotor helicopters available from various manufacturers. All of these systems rely on a low cost MEMS based inertial measurement system for stabilization and navigation.

Introgression of chromosomal segments conferring early heading date from wheat diploid progenitor, Aegilops tauschii Coss., into Japanese elite wheat cultivars. [PDF]

open access: yesPLoS ONE, 2020
The breeding of agriculturally useful genes from wild crop relatives must take into account recent and future climate change. In Japan, the development of early heading wheat cultivars without the use of any major gene controlling the heading date is ...
