Enabling breeding of spring wheat for optimisation of flowering time for current and future climates by linking genetic maps to simulation model parameters

In Australian wheat production, optimizing wheat phenology is essential to reach yield potential and to avoid within‐season stress at critical periods, especially around flowering. Identifying loci that determine heading date of wheat cultivars and …

Identification of Earliness Per Se Flowering Time Locus in Spring Wheat through a Genome-Wide Association Study

Identification of earliness per se (Eps) flowering time loci in spring wheat are troublesome due to confounding effects of vernalization and photoperiod responses. The Wheat Association Mapping Initiative panel of 287 elite lines was assessed to …

Quantitative evaluation of influence of PROSTRATE GROWTH 1 gene on rice canopy structure based on three-dimensional structure model

The discovery and separation of the PROSTRATE GROWTH 1 gene has significantly contributed to reveal the molecular mechanism of rice evolution and has aided the study of the molecular basis of rice plant architecture. However, the influence of the …

Gene-based prediction of heading time to target real-time and future climate adaptation in wheat

Spring wheat production systems in Australia require fine-tuning of heading time in order to maximise the efficient use of resources (radiation, water, fertiliser) across the season, while minimising the risk of crop failure due to frost, heat and …

Predicting heading time of Australian wheat using effects of VRN1 and Ppd-D1

Flowering time is a main determinant of wheat adaptation to diverse environments and is influenced by three groups of genes, earliness per se (EPS), VRN and PPD. The gene-based models, used known genes to predict wheat phenotype, would be robust for …

Using gene-based information to adapt wheat flowering time to avoid heat, frost and drought stresses in current and future climates

Varying the timing of reproductive stages of growth relative to climatic stresses is a useful adaptation to maintain yields. In future climates, the expectation that heat, frost and drought stresses may change in their timing means requires that …

Quantification of the effects of VRN1 and Ppd-D1 to predict spring wheat (Triticum aestivum) heading time across diverse environments

Heading time is a major determinant of the adaptation of wheat to different environments, and is critical in minimizing risks of frost, heat, and drought on reproductive development. Given that major developmental genes are known in wheat, a …

Association genetics for earliness components and QTL-based ecophysiological predictions of heading date provide tools to optimize heading date through breeding
