Classification of Jerusalem artichoke accessions by linear discriminant analysis of mineral concentration in tubers and leaves
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2011)
Linear discriminant analysis (LDA) was used to classify 138 accessions of Jerusalem artichoke (Helianthus tuberosus L.). The analysis was performed using mineral element concentrations of tubers and leaves for N, P, Ca, ...
Screening wild sunflower species and F1 interspecific hybrids for resistance to broomrape
(Institut za ratarstvo i povrtarstvo, Novi Sad, 2010)
Broomrape has become one of the most important threats to the cultivated sunflower. New sources of resistance genes are needed to maintain sunflower production. The objective of this research was to evaluate accessions of ...
