| ABSTRACT The present study resulted from the lack of information on the genotypic expression ruling the resistance to rust and on the main traits of economic importance to the herein addressed crop. The combining ability of 16 popcorn lines and hybrids was assessed in partial diallel cross in two representative locations in Rio de Janeiro State, Brazil, where forty simple hybrids were obtained. The experiments followed a completely randomized block design with four repetitions and were conducted under natural infestation conditions in order to test the southern rust severity in the entire plant (SSW) and in the leaf of the first ear (SFPE), as well as the morpho-agronomic traits of greater interest: grain yield (GY) and popping expansion (PE).

| ABSTRACT Because of its multi-purpose nature, popcorn has sparked the interest of the World Trade Organization as regards fungal contamination by mycotoxins. However, no investigations have been conducted on popcorn for resistance of genotypes to ear rot. The aim of this study was to evaluate the potential of popcorn genotypes as to resistance to ear rot and rotten kernels, as an initial step for the implementation of a breeding program with the popcorn crop in Northern Rio de Janeiro State, Brazil. Thirty-seven accessions from different ecogeographic regions of Latin America were evaluated in 2 cultivation periods, in a randomized block design with 4 replications. We evaluated the incidence of rotten ears, incidence of rotten ears caused by Fusarium spp.,... |

| ABSTRACT We evaluated the contents of dry matter (DM), crude protein (CP), mineral matter (MM), soluble carbohydrates (CHOS), ammonia nitrogen (N-NH3), neutral detergent fiber (NDF), and acid detergent fiber (ADF) in sugarcane silages to which different levels of inclusion (LI) of crambe bran (CB) were added in proportions of 0, 3, 10, 17 and 20% at different storage times (ST). Laboratory silos were used, predetermined ST being 0, 3, 7, 12, 24, 36, 41, and 60 days after silage. For statistical analysis, the response surface methodology was used, in which LI and ST served as independent factors and response variables as dependent factors. The levels of DM and CP increased linearly with NI; however, it did not show any significant response regarding ST. The... |
