Abstract:
... Crop breeding aims to generate pure inbred lines with multiple desired traits. Doubled haploid (DH) and genome editing using CRISPR/Cas9 are two powerful game-changing technologies in crop breeding. However, both of them still fall short for rapid generation of pure elite lines with integrated favorable traits. Here, we report the development of a Haploid-Inducer Mediated Genome Editing (IMGE) app ...

The objective of this study was to determine the influence of two silicon- and nitrogen-based products applied at two rates on borer infestation. To compare the effect of these two amendments, a completely randomized block design wa ...

Abstract:
... Crop yield can be affected by crop water use and vice versa, so when trying to simulate one or the other, it can be important that both are simulated well. In a prior inter-comparison among maize growth models, evapotranspiration (ET) predictions varied widely, but no observations of actual ET were available for comparison. Therefore, this follow-up study was initiated under the umbrella of AgMIP ...

Abstract:
... Phytic acid (PA) is considered as antinutrient in food and feed. Several low phytic acid (lpa) rice (Oryza sativa L.) mutants have been generated through induced mutation. Lpa mutant lines often exhibit inferior agronomic performance, and cross-breeding is applied to minimize these effects. The impact of such crossing steps on the PA contents in the resulting progenies is unknown. Therefore, three ...
