【 摘 要 】

In the three year experiment (2005, 2006, 2007) the effects of hybrid, sowing date and their interaction for seed yield and oil content in sunflower were investigated. Three hybrids (Miro, Rimi, Pobednik) and eight sowing dates were included in the experiment. AMMI (Additive Main effects and Multiple Interaction) model was applied (Gauch & Zobel, 1996). AMMI1 biplot, using excel (macro) was done according to Lipkovich & Smith (2002). In the three years average, hybrids did not show significant differences in the mean values for seed yield. Sowing dates had significant portion in the yield formation. The highest seed yield was achieved in the earlier sowing dates. From R3 to R6 the seed yield stagnated, and in R7 and R8 the mean values were significantly lowest. Hybrid Pobednik showed significantly highest oil content. Oil content (three years average) was highest in R2, R4 and R5, after that mean values decreased and they were lowest in R7 and R8. AMMI ANOVA for seed yield and oil content showed highly significant values for IPC1 (73,8 % of variation for seed yield and 69,4 % for oil content). On the basis of the stability evaluation for seed yield and oil content on AMMI1 biplot can be seen that hybrid Miro was most stable, and hybrids Pobednik and Rimi were less stable. Highly significant positive correlation with IPC1 for seed yield had pa_cv and rv_cv (precipitation and relative air humidity in the flowering stage) and significant correlation rv_fz (relative air humidity in the physiological maturity). Highly significant or significant correlation with first bilinear component for oil content showed tmx_cv, tsd_cv and os_cv (maximum decade temperature, mean decade temperature and insolation in the flowering stage). AMMI1 biplot can help in the recommendation of high yielding, stable sunflower hybrids and most convenient sowing dates. .
