Breeding to Optimize Chinese Agriculture(OPTICHINA) was a three-year EU–China project launched in June of 2011. As designed, the project acted as a new strategic model to reinforce systematic cooperation on agricultural research between Europe and China. The OPTICHINA International Conference "Breeding to Optimize Agriculture in a Changing World" was held in Beijing, May 26–29, 2014. The conference included six thematic areas:(1) defining and protecting the yield potential of traits and genes;(2) high-throughput precision phenotyping in the field;(3) molecular technologies in modern breeding;(4) plant ideotype;(5) data analysis,data management, and bioinformatics; and(6) national challenges and opportunities for China. The 10 articles collected in this special issue represent key contributions and topics of this conference. This editorial provides a brief introduction to the OPTICHINA project, followed by the main scientific points of articles published in this special issue. Finally, outcomes from a brainstorming discussion at the end of the conference are summarized, representing the authors' opinions on trends in breeding for a changing world.

Capillary hydrodynamic fractionation（CHDF） with turbidity detection at a single wavelength is an analytical technique that is often used for sizing the sub-micrometric particles of hydrophobic *** article investigates three sources of errors that affect the particle size distribution（PSD） estimated by CHDF：diameter calibration errors,uncertainties in the particle refractive index（PRI）,and instrumental broadening（IB）.The study is based on simulated and experimental examples that involve unimodal and bimodal *** errors in the diameter calibration curve can produce important deviations in the number average diameter due to systematic shifts suffered by the PSD *** uncertainties in the PRI are unimportant in the analysis of unimodal PSDs,but in the specific case of bimodal PSDs,errors in the PRI can strongly affect the estimated number concentration of each *** typical IB correction（based on the IB function estimated from narrow standards） produces slightly erroneous average diameters but can lead to PSDs with underestimated widths and distorted *** practice,the three investigated sources of errors can be present simultaneously,and uncertainties in the average diameters,the shape and width of the PSD,and the number concentration of the PSD modes are unavoidable.

Food security is a global concern in view of the ongoing global （social and climate） change. The challenges to food securityfrom global change, sharply increasing food and feed demands, whereas increasing the frequency and severity of stresses,coupled with degradation and scarcity of natural resources, are indeed urgent and real （Prasanna et al. 2013）. Crop productionmust double by 2050 to meet future production demands （Tilman et al. 2011）. The ability to achieve this increaserepresents a significant challenge to plant breeders. Crop yields must increase at a rate of 2.47o per year, yet the averagerate of increase is only 1.3% with yields stagnating in up to 40% of land under cereal production （Ray et al. 2012, 2013）. Therefore,crops with higher yield potential and more resistant to abiotic stress conditions are needed to address such challenges.
