Short title: GOME-derived NO x emissions over ChinaAbstract: 1 Observations of tropospheric column densities of NO 2 obtained from the Global Ozone 2 Monitoring Experiment (GOME) for a 3-year period (1997, 1998, and 2000) are used to derive 3 average seasonal variations in surface emissions of NO x from east China (100 o E-123 o E, 20 o N-4 42 o N).

Twenty Brassica breeding populations derived from mass selection or inter-specific hybridization were field screened for resistance to three separate isolates of Sclerotinia sclerotiorum, the cause of Sclerotinia stem rot (SSR). Variation due to S. sclerotiorum isolates (P ≤ 0.001) and host populations (P ≤ 0.001) were highly significant. Populations ×(More)
Aiming to explore the basis of heterosis in rapeseed, QTLs for yield and three yield component traits were mapped and the digenic interactions were detected in an F2 population derived from a cross between two elite rapeseed lines, SI-1300 and Eagle, in this study. Twenty-eight QTLs were detected for the four yield traits, with only two of them detected(More)
