摘要

Two field bean (Vicia faba L. var. minor Peterm.) breeding selections are described and the results on the grain yield data collected in eight location-year combinations are discussed. The investigation involved the selections MG109263, MG109307, the variety Torre Lama Chiaro as reference test, and 10 faba bean accessions extracted from Vicia faba germplasm collection of Bari IBBR-CNR Gene Bank. The tests were carried out in in three locations in 4 years 2008, 2009, 2010 and 2011 according to a randomized block design with three replications. According to Finlay and Wilkinson method, a linear regression of individual grain yield on the mean yield of each location-year combination was computed. The field bean selection MG109263 resulted the most productive at the experimental fields of Matera in the year 2008, at Metaponto and Lecce in the year 2009; a similar trend, with lower yields, was found in MG109307. The results showed a significant difference between the field bean selections in different location-year combinations; indeed are pointed out two major issues: (1) the performance of each genotype is a linear function of environment parameters; (2) the genotype x environment interactions could be explained, for a large part, by variations in the linear response computed through the regression analysis. The implications on future selection breeding programs for a wider diffusion in marginal areas of these improved field bean populations are discussed.
