The plant vigour and the biomass production were evaluated in Portuguese germplasm (15 individuals from 16 ecotypes) by non-destructive methods, 2 years following planting in a marginal soil and dryland conditions. Two Italian cultivars (Gialla and Bianca) were included in the study for comparison purposes. The biomass production and the plant vigour were estimated by measuring the cladodes number and area, and the fresh (FW) and dry weight (DW) per plant. We selected linear models by using the biometric data from 60 cladodes to predict the cladode area, the FW and the DW per plant. Among ecotypes, significant differences were found in the studied biomass-related parameters and several homogeneous groups were established. Four Portuguese ecotypes had higher biomass production than the others, 3.20 Mg ha<jats:sup>\u22121<\/jats:sup> on average, a value not significantly different to the improved \u2018Gialla\u2019 cultivar, which averaged 3.87 Mg ha<jats:sup>\u22121<\/jats:sup>. Those ecotypes could be used to start a breeding program and to deploy material for animal feeding and fruit production.<\/jats:p>","DOI":"10.1017\/s0014479716000211","type":"journal-article","created":{"date-parts":[[2016,4,13]],"date-time":"2016-04-13T03:59:16Z","timestamp":1460519956000},"page":"227-242","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":16,"title":["ABOVE-GROUND BIOMASS ESTIMATION OF <i>OPUNTIA FICUS-INDICA<\/i> (L.)
