Rice cultivar responses to elevated CO2 at two free-air CO2 enrichment (FACE) sites in Japan.
Functional Plant Biology, 2013 There is some evidence that rice cultivars respond differently to elevated CO2 concentrations ([CO2]), but [CO2]×cultivar interaction has never been tested under open-field conditions across different sites.

Plant variety and cultivar identification: advances and prospects
Critical Reviews in Biotechnology, 2013 Plant variety and cultivar identification is one of the most important aspects in agricultural systems. The large number of varieties or landraces among crop plants has made it difficult to identify and characterize varieties solely on the basis of ...

Analysis of genetic diversity among some Iraqi durum wheat cultivars revealed by different molecular markers [PDF]
Durum wheat has been cultivated since the beginning of crop domestication, occupying now the tenth ranking among the global most significant cultivated crops. Despite the fact that, the extent of the crop genetic diversity has not yet fully incorporated into modern varieties through breeding programs.

Nonparametric Testing for Heterogeneous Correlation [PDF]
arXiv, 2015 In the presence of weak overall correlation, it may be useful to investigate if the correlation is significantly and substantially more pronounced over a subpopulation. Two different testing procedures are compared. Both are based on the rankings of the values of two variables from a data set with a large number n of observations.

Adaptation in a heterogeneous environment. I: Persistence versus extinction [PDF]
arXiv, 2020 Understanding how a diversity of plants in agroecosystems affects the adaptation of pathogens in a key issue in agroecology. We analyze PDE systems describing the dynamics of adaptation of two phenotypically structured populations, under the effects of mutation, selection and migration in a two-patches environment, each patch being associated with a ...

Cultivar Differences in Root Nitrogen Uptake Ability of Maize Hybrids
Frontiers in Plant Science, 2017 Although, considerable differences in root size in response to nitrogen (N) application among crop species and cultivars have been widely reported, there has been limited focus on the differences in root N uptake ability.
