Abstract
Performance of 25 new sunflower hybrids at three locations in Romania were estimated using AMMI model. Seed yield per plot were recorded on plants in middle rows to avoid edge effect. The most productive hybrid was NS-6 (4.31 t/ha), while the least productive was NS-13 (2.80 t/ha). The highest yield was obtained by hybrid NS-24 in location Valul lui Traian with seed yield of 5.03 t/ha, while the lowest seed yield was 1.43 t/ha obtained by hybrid NS-13 in location Dalga. AMMI analysis showed that variations in seed yield were mostly due to additive effects, genotype (32.45%) and environment (41.62%), but interaction effect (25.92%) was also not negligible. The most productive hybrids with high yields and low values of interaction were NS-1, NS-2, NS-4, NS-5, NS-6, NS-9, NS-10, NS-11 and NS-16.
