Ten traditional and unbranched cultivars of narrow-leafed lupin (Lupinus angustifolius L.),<br />

differentiated in terms of morphological structure and phenological phases, were studied. Field<br />

experiments were conducted at Wiatrowo and Radzików in 2011 and 2012 in randomized<br />

complete block design. Assessment of seed yield and its stability for various cultivars in different<br />

environments were the main goal of the research. Weather conditions were characterized using<br />

the Sielianinow factor. The results were analyzed statistically. Highly significant (α=0.01)<br />

differences between cultivars of lupin were observed. The analysis of series of trials across<br />

environments was performed and stability of cultivars assessed. The stability of cultivars was<br />

different. Analysis of variance for localization showed that among lupin the Neptun, Regent,<br />

Zeus, Dalbor and Kadryl cultivars yielded above average for the species. Analysis of interactional<br />

deviations showed that the most stable lupin were the Boruta, Kalif and Zeus cultivars. Based on<br />

correlation analysis, it was found that t<strong>here</strong> were differences between the high and low cultivars<br />

of lupins (the length of the flowering phase). The length of the generative phase was correlated<br />

with the Sielianinow factor in all the studied cultivars. In case of regression analysis, seed yield<br />

and seed yield components were related to the Sielianinow factor. Multiple regression was applied<br />

in order to determine the relationships between seed yield and its components and the<br />

Sielianinow factor in two different phases (flowering and generative). Account of differences<br />

between the cultivars in terms of the discussed traits increases the value of the determination<br />

factor in all the analyzed traits, which suggests the need to focus attention on cultivars.<br />
