Phenotyping Almond Orchards for Architectural Traits Influenced by Rootstock Choice

The cropping potential of almond (Prunus amygdalus (L.) Batsch, syn P. dulcis (Mill.)) cultivars is determined by their adaptation to edaphoclimatic and environmental conditions. effects scion–rootstock interactions on vigor have a decisive impact this success. Intensively planted orchards with smaller less vigorous trees present several benefits for increasing orchard profitability. While studies examined rootstock tree vigor, it clear how rootstocks influence more specific aspects architecture. objective current study was identify which architectural traits commercially important scion are influenced these can be useful as descriptors performance in breeding evaluations. To do this, 6 commercial significance were grafted onto 5 hybrid rootstocks, resulting 30 combinations that measured after second year growth. We observed choice mainly branch production, but the not consistent across different evaluated. This lack consistency response highlights importance unique interaction between each its respective genotype.
