Agronomic characteristics and nutritional value of cactus pear progenies

Cactus is an important fodder in tropical semiarid, but recent insect pressure has devastated cactus crops. Breeding programs are developing cactus varieties resistant to cochineal scale (Dactylopius opuntiae Cockerell). The cactus V‐19 (Opuntia larreyi F.A.C. Weber ex J. M. Coult.) has demonstrated...

Description
Summary:Cactus is an important fodder in tropical semiarid, but recent insect pressure has devastated cactus crops. Breeding programs are developing cactus varieties resistant to cochineal scale (Dactylopius opuntiae Cockerell). The cactus V‐19 (Opuntia larreyi F.A.C. Weber ex J. M. Coult.) has demonstrated resistance to cochineal scale, however, no breeding effort has been attempted with this species. This study characterized the resistance of cactus V‐19 progenies to cochineal scale. Morphological, productive, and nutritive value variables were evaluated in 11 genotypes of cactus V‐19, in which 10 (named as P1, P2, P3, P4, P5, P6, P7, P8, P9, and P10) were progenies resulted from open pollination. Two evaluations were carried out from 2015 to 2017, corresponding to first and second harvest years. A randomized complete design with seven replications were used. There was a harvest (year) × progeny interaction (p
