106 trees delivered higher yields per plant, M.9 EMLA yield efficiency (no. The highest productions in ‘Brookfield ®Gala’, ‘Galaxy’, ‘Granny Smith’, ‘Cripp's Pink’, and ‘Super Chief’, regardless of rootstock, were obtained in San Clemente and Chillan's blocks.
This rootstock also had 50% smaller TCAs than M.M.106’s at Year 6 in most cultivars. M.9 EMLA rootstock reduced tree height by ≈20% in ‘Brookfield ® Gala’, ‘Fuji’, ‘Galaxy’, and ‘Granny Smith’. In general, tree growth rates by the end of the third year, when they reached the desired height, were similar in all block locations. Tree height and volume, trunk cross-sectional area (TCA), fruit yield and size distribution, crop load, and tree phenology were assessed annually.
Second-leaf trees were planted in experimental blocks inside commercial orchards located in five major apple-producing areas in Chile (Graneros, San Clemente, Chillan, Angol, and Temuco). Performance of seven apple ( Malus × domestica Borkh.) cultivars (‘Brookfield ®Gala’, ‘Galaxy’, ‘Super Chief’, ‘Granny Smith’, ‘Fuji Raku Raku’, ‘Cripp's Pink’, and ‘Braeburn’) on M.M.106 and M.9 EMLA rootstocks during their first 6 years was evaluated on a multisite trial in Chile.
