“…Rootstock involvement in more specific aspects of tree architecture is less clear, and there is often a lack of consistency in responses among different cultivars, which highlights the importance of scion-rootstock interactions [10,12]. While previous studies with almond have described rootstock effects on vigor in generic terms [13,14], knowledge of rootstock influence on more specific architectural traits and their wider influence over almond tree architecture is still limited.…”

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

“…These reports are in line with previous research that have shown how rootstocks might also induce less trivial scion morphological changes, such as dwarfing, and even alter yield traits and fruit quality ( Egea et al, 2004 ; Picolotto et al, 2010 ; Madam et al, 2011 ; Expósito et al, 2020 ; Kviklys and Samuoliene, 2020 ). For instance, rootstock effects may even influence properties typically attributed to the clonal Hass scion, such as fruit sensorial and nutritional quality, e.g., texture, sugar content, acidity, pH, flavor, and color ( Giorgi et al, 2005 ; Gullo et al, 2014 ; Balducci et al, 2019 ), cold tolerance, and shoot pest and pathogen resistance ( Rubio et al, 2005 ; Goldschmidt, 2014 ).…”

Inheritance of Yield Components and Morphological Traits in Avocado cv. Hass From “Criollo” “Elite Trees” via Half-Sib Seedling Rootstocks

Grafting induces precocity and maintains clonal integrity in fruit tree crops. However, the complex rootstock × scion interaction often precludes understanding how the tree phenotype is shaped, limiting the potential to select optimum rootstocks. Therefore, it is necessary to assess (1) how seedling progenies inherit trait variation from elite ‘plus trees’, and (2) whether such family superiority may be transferred after grafting to the clonal scion. To bridge this gap, we quantified additive genetic parameters (i.e., narrow sense heritability—h2, and genetic-estimated breeding values—GEBVs) across landraces, “criollo”, “plus trees” of the super-food fruit tree crop avocado (Persea americanaMill.), and their open-pollinated (OP) half-sib seedling families. Specifically, we used a genomic best linear unbiased prediction (G-BLUP) model to merge phenotypic characterization of 17 morpho-agronomic traits with genetic screening of 13 highly polymorphic SSR markers in a diverse panel of 104 avocado “criollo” “plus trees.” Estimated additive genetic parameters were validated at a 5-year-old common garden trial (i.e., provenance test), in which 22 OP half-sib seedlings from 82 elite “plus trees” served as rootstocks for the cv. Hass clone. Heritability (h2) scores in the “criollo” “plus trees” ranged from 0.28 to 0.51. The highesth2values were observed for ribbed petiole and adaxial veins with 0.47 (CI 95%0.2–0.8) and 0.51 (CI 0.2–0.8), respectively. Theh2scores for the agronomic traits ranged from 0.34 (CI 0.2–0.6) to 0.39 (CI 0.2–0.6) for seed weight, fruit weight, and total volume, respectively. When inspecting yield variation across 5-year-old grafted avocado cv. Hass trees with elite OP half-sib seedling rootstocks, the traits total number of fruits and fruits’ weight, respectively, exhibitedh2scores of 0.36 (± 0.23) and 0.11 (± 0.09). Our results indicate that elite “criollo” “plus trees” may serve as promissory donors of seedling rootstocks for avocado cv. Hass orchards due to the inheritance of their outstanding trait values. This reinforces the feasibility to leverage natural variation from “plus trees”viaOP half-sib seedling rootstock families. By jointly estimating half-sib family effects and rootstock-mediated heritability, this study promises boosting seedling rootstock breeding programs, while better discerning the consequences of grafting in fruit tree crops.

“…The rootstock influence on the yield and quality of cherry fruits was examined by a number of authors [25][26][27][28][29][30][31]. Trees on low-vigorous rootstocks are, in most cases, more productive than trees on vigorous ones [32].…”

Over the past few decades, numerous studies investigated the vigor and productivity of fruit species depending on the rootstock on which they were grafted, but the exact size-controlling mechanism itself has not been fully elucidated, nor were the rapid rootstock selection methods defined. Thus, this study aimed to assess the root anatomical characteristics and their influence on the overall ‘Summit’ cherry tree vigor to confirm the size-controlling effect and establish an effective protocol for rapid rootstock selection. Plant material included three cherry species (Prunus cerasus, Prunus fruticosa, and Prunus mahaleb) and interspecific hybrid ‘Gisela 5′ (P. cerasus × Prunus canescens) as a control. The detailed anatomical analysis included root samples with the differentiated secondary structure taken from the sampling depth of 10–15 cm. Roots with percentages of vessels ≈40%, ≈50%, and ≈10% belonging to size-classes ˂700 µm2, 700–2000 μm2, and ˃2000 µm2 (respectively) are presumed to provide optimal amounts of water solution to the scion, without compromising plant vitality, drought tolerance, and size-controlling effect. Statistically significant correlations were determined between anatomical properties (the percentage of vessels, especially ˃2000 µm2, xylem porosity, and hydraulic conductivity, both per mm2 and total root) and vegetative growth in the juvenile vegetative phase, indicating direct vessel size influence on plant vigor and its employment in size-controlling cherry rootstock selection.
