Correlations among morphological traits of sweet chestnut (<i>Castanea sativa</i> Miller) from Bosnia and Herzegovina

Abstract Sweet chestnut forests in Bosnia and Herzegovina are underrepresented the total forest fund, their area is declining today. The research aims to determine correlation relations of morphological traits leaves, fruit cupule population Bosnian Krajina (northwestern Herzegovina) undertake selection breeding activities. Eleven fruits, leaves cupules were measured, seven assessed six calculated. A mutual for researched was calculated using Pearson coefficient r . When compared, needle length showed a statistically significant with most traits. number fruits had leaf blade width petiole length. correlated can be distinguished as important further sweet chestnuts. results indicate that genetic material rich source diversity used obtain new varieties cultivars protection indigenous gene pool.
