“…In this study, genotypes had a DRC that ranged from 26.24% to 32.83%. These results are lower than those reported by Mendoza-Vargas and Jiménez-Forero [50] (i.e., DRC of 34.3%) in a promising clonal collection from the FX series in Cundinamarca, Colombia. Furthermore, the percentages obtained are lower than those reported by Ajith et al [51] in two locations in India (i.e., DRC ranged from 35.23% to 48.9%).…”

“…Furthermore, the percentages obtained are lower than those reported by Ajith et al [51] in two locations in India (i.e., DRC ranged from 35.23% to 48.9%). The DRC values of IAN 873 (control) were also lower than those reported by Quesada-Méndez et al [48] in genotypes three years after planting (i.e., DRC of 40.91%) and lower than those reported by Mendoza-Vargas and Jiménez-Forero [50] (i.e., DRC of 41.3%).…”

“…The dry rubber yield (DRY) (g.tree −1 .tap −1 ) was recorded during the first six months of tapping, following the methods described by Meenakumari et al [37] and Silva et al [64]. The dry rubber content (DRC) as a percentage was measured according to the method described by Lacote et al [65] and Mendoza-Vargas and Jiménez-Forero [50].…”

The cultivation of Hevea brasiliensis, the primary commercial source of natural rubber, is strongly impacted by South American leaf blight (SALB) disease, caused by the fungus Pseudocercospora ulei. Various management strategies have been implemented, including the selection of resistant genotypes and the identification of escape zones. This study evaluated the growth, early yield, and resistance to SALB of nine Colombian elite genotypes from the ECC-100 series and IAN 873 clone (control) in a large-scale clone trial in an area with low SALB pressure in the Colombian Amazon during 2017–2020. Favorable early performance was evident, although there was a significant increase in the severity and sporulation of P. ulei over time, especially in the ECC 35, ECC 60, and IAN 873 genotypes. However, these scores indicate low susceptibility. Genotypes with higher resistance to SALB demonstrated greater growth and early yield compared to more highly susceptible genotypes. The ECC 64, ECC 73, ECC 90, ECC 25, and ECC 29 genotypes were more desirable in low SALB pressure zones due to their higher resistance and early performance. It is important to highlight that this research contributes to the selection of new SALB-resistant Colombian genotypes of H. brasiliensis. However, it is also necessary to evaluate the productivity of these selections in the mature stage and long-term resistance to SALB before recommending and promoting their commercial adoption in the Colombian Amazon.
