Biplot analysis of sunflower plant height on different soils and precipitations

Plant height is one of the most important sunflower traits, which has great impact on grain and oil yield. Field trials are conducted on three locations (Osijek- Eastern Slavonia, Karanac- Baranja and Feričanci- Western Slavonia) with different pedodynamic soil characteristics. Investigation includes 7 single cross and 7 three-way cross experimental and recognized sunflower hybrids of The Agricultural institute Osijek during two growing seasons. Single cross hybrids had a slightly higher plant height values in relation to three-way cross hybrids. The lowest plant height value in both years of investigation is obtained on location Feričanci, and the highest in Osijek. In the second year of investigation, in lack of precipitations, plants were lower 37 cm in average. Estimation of IPCA1 values showed that the highest stability had experimental hybrids OS-253 T, OS-H-101 S and OS-H-219 S.
