SUMMARY:

The selection and cultivation of forage cactus genotypes that are adapted and resistant to pests, such as the carmine cochineal, as well as the main diseases, offer a viable and economical solution for producers. Therefore, this study aimed to evaluate 10 genotypes of Opuntia spp. and Nopalea sp. with proven resistance to the false carmine cochineal in terms of morphological, productive, and chemical-bromatological aspects under the conditions of the Agreste Meridional of Pernambuco, Brazil. To this end, a field competition trial was established in the municipality of Garanhuns-PE, containing six genotypes of Opuntia spp. (IPA-200016, IPA-200174, IPA-100661, IPA-100662, IPA-200149, and IPA-200008) and four genotypes of Nopalea sp. (IPA-200205, IPA-100004, IPA-200206, and IPA-100664) distributed in randomized block design (RBD) with 3 replicates and 20 plants per plot. Over 420 days after planting (DAP), survival percentage, vegetative phenology, growth and development, production components, fresh and dry matter productivity, and chemical-bromatological composition were evaluated. Plant mortality was higher in the first 60 days, except for IPA-200174, which was affected by the carmine cochineal after this period. The genotype IPA-200008 showed the best performance in all evaluated morphoagronomic traits (plant height, crown width, number of cladodes, and cladode area) and in production and productivity variables when compared to traditionally cultivated genotypes (IPA-200016 and IPA-100004). Additionally, IPA-200008, along with IPA-200149, had the highest crude protein contents, essential for the diet of ruminal microorganisms. The genotypes IPA-200016, IPA-100662, and IPA-100004 also showed good performance in terms of dry and organic matter, while IPA-200174, IPA-100661, and IPA-200149 presented higher mineral matter content. Choosing the right genotype, combined with appropriate management practices, can maximize the productivity and adaptability of forage cacti, making them a viable and sustainable alternative for producers in the region.
