“…According to Fachinello et al (2005), in cultivars of later ripening, in addition to increased endocarp mass, the seeds present larger fresh mass and consequently better developed embryos, directly influencing the germination percent and the GSI. When seeds were stratified without the endocarp, most of the cultivars presented 100% germination, except the cultivars Flordaguard, Tsukuba 2 and 3, which presented 93% germination (Table 2).…”

“…In Rio Grande do Sul, in addition to the stones obtained in industries, seeds of the cv. 'Capdeboscq' have been utilized in the production of rootstocks for a variety of peach tree and plum tree scions since they have a late cycle, which enables adequate development of the embryo (Fachinello et al, 2005). Other recent alternatives of rootstocks (Picolotto et al, 2012) include 'Tsukuba 1' and 'Flordaguard', due mainly to the resistance to Meloidogyne spp.…”

-The present study evaluated the germination potential of seeds from eight peach tree rootstocks under different stratification methods, aiming at the production of high quality seedlings. In the first experiment, seeds with endocarp from eight genotypes ('Aldrighi', 'Capdeboscq', 'Flordaguard', 'Okinawa', 'Okinawa roxo', 'Tsukuba 1', 'Tsukuba 2', 'Tsukuba 3') were stratified on sand and moist vermiculite, at 7 ºC for 60 days. In the second experiment, endocarpless seeds of the same genotypes were stratified on Petri dishes at 7 ºC. In the third experiment, the time at which at least 75% of the seedlings reached transplanting height (15 cm high) was verified. The endocarp was a limiting factor for seed germination of the eight rootstocks, since the highest germination percentages were 21% and 48.3% for 'Aldrighi' and 'Capdeboscq', respectively. Germination of 'Okinawa' was only 19.2% and 4.2%, in sand and vermiculite, respectively. Seeds stratified without the endocarp, showed 100% germination, except for 'Flordaguard' and 'Tsukuba 2' and 3', with 93% germination. Seed mass presented a positive correlation with the germination speed index and the initial growth of the seedlings. 'Aldrighi' and 'Capdeboscq' presented more vigorous seedlings with greater growth in height, stem diameter, and Dickson quality index.

“…Despite the expansion of clonal rootstocks, seedling rootstocks continue play a pivotal role in apple seedlings production in many countries. Grafted trees on seedling rootstocks are very vigorous but diverse and are produced easily at a low cost (Webster, 1995). Apple rootstocks vary in their adaptation to soil and climatic conditions, resistance to diseases and tree size and vigor (Anderson et al, 1984;Ferree & Warrington 2003).…”

Present study was conducted in 2014-2015 to decrease genetic variability in apple seed rootstocks in order to produce trees with morphological uniformity. Effect of two different Half-Sib seed lots of "Morabbaei" was compared on 7-Year-old trees of the six apple commercial cultivars. The open pollinated seed lots were collected from selected maternal parents as two homonym Iranian native self compatible crabs "Morabbaei" characterized by different origin viz.. Isfahan and Karaj. Results of study revealed that the rootstock, graft point and trunk diameters were not significantly affected by different seed lots, scion and their interaction. The highest mean of shoot number was reported in "Red Delicious" on "Morabbaei1" seed rootstocks, for both years. Further, no significant difference was observed in case of branch angle in "Granny Smith", "Braeburn", "Gala" and "Golab-e Kohanz" grafted on the two seed lots of "Morabbaei1" and on "Morabbaei2". The highest number of lenticels was reported in "Golab-e Kohanz" on Morabbaei1 seed stock, in the first year of study. All tree growth components including shoot length, shoot thickness and internode length were significantly affected at 1% level by year, rootstock and scion interaction. In general, except stable traits of the cultivars, the studied rootstocks induced similar vegetative behavior in the scions causing improved tree uniformity.

“…Severe hedge pruning of mother plants improves rooting success (Webster 1995). Hardwood cuttings taken shortly after leaf fall or before bud break root better than those taken in midwinter (Webster 1995). Additionaly, treating cuttings with synthetic auxin indole-3-butyric acid (IBA) solution improves the RR (Howard 1968),…”

Vegetative propagation enables the multiplication of plants that are genetically identical to the original. Hardwood cuttings have a low cost advantage and are used widely for the propagation of JM series apple rootstocks, which root well from hardwood cuttings. To breed new apple rootstocks with similarly high rooting capabilities, the development of a marker-assisted selection method is desirable. Therefore, it is important to understand the genetic mechanisms behind the rooting capabilities of hardwood cuttings. We identified quantitative trait loci (QTLs) for the rooting capability of 'JM7' using a QTL analysis with phenotypic data obtained under two environmental conditions. The QTLs for rooting rate and root quantity co-located. The QTL for rooting rate explained 66 % of the genetic variance and 57 % of the phenotypic variance. Graphical genotyping and database searching revealed candidate genes, including three related to auxin response, one related to ethylene response, and a gene encoding a WRKY transcription factor.
