In the CSO of C. angustifolia, 64 clones were initially planted, corresponding to
seven populations of Salta, three of Tucumán, and two of Jujuy, with five replicates
per clone (N = 320). Subsequent mortality reduced the number of clones to 44
(N = 85). The initial distance between plants was 4 m × 4 m, thus occupying an area
of 0.5 ha (27° 1′ 13.89″ S, 65° 22′ 53.66″ W, 375 m asl).
C. fissilis CSO initially had 42 clones from five populations of Misiones and
Corrientes, with nine replicates per clone (N = 378) (Fig. 14.12b). Currently, it consists in 77 clones since genotypes were added over time, although the number of
ramets was reduced by mortality to 155. It occupies an area of 1.5 ha with a distance
of 5 m × 7 m between plants and is located at 27° 1′ 50.22″ S, 65° 22′ 46.48″ W
(365 m asl).
In 2016, seed production started in the orchards of C. fissilis and C. balansae.
However, production still fluctuates from year to year, and several clones have not
yet came to fruited. A significant portion of the seeds collected still has low germination capacity. It is estimated that production will stabilize in 2022.
