The Mesoamerican and Andean gene pools of the common bean are distinguished into specific races. Knowledge of their structure and genetic diversity is an important prerequisite for plant conservation and breeding. The aim of this study was to estimate the inter- and intra-racial genetic diversity of genotypes representative of the six common bean races using simple sequence repeats (SSRs) and single nucleotide polymorphism (SNPs). Ninety-four accessions were genetically analyzed, using 24 SSR and 4.820 SNPs markers with minor allele frequencies (MAF)>- 5%. Based on SSR, 163 alleles were identified (13.8 alleles/marker). For the whole samples, the average values for expected (He) and observed heterozygosity (Ho) were 0.780 and 0.045, respectively, and 5.5 × 10-31 for probability of identity (PI). While for the gene pools analyzed separately, similar He estimates were obtained for the Andean (He = 0.731) and Mesoamerican gene pools (He = 0.733). Population structure and clustering analyses revealed subdivision predominantly by gene pool (K = 2). The overall linkage disequilibrium extension (r2sv) was 58 kb. Estimated He was 0.327 and Ho 0.025, with slightly higher values for the Mesoamerican (He= 0.303) when compared to its Andean counterpart (He = 0.269). Population structure was observed in the Andean (K = 2 and K = 3) and Mesoamerican (K = 2) gene pools. The molecular analyses did not reveal clear differentiation between the bean races. Although sampling may be having an effect on the analysis, our results reinforce that distinction among races appeared to have resulted from selection caused by domestication.

The goal was to evaluate the productive performance, nutrient digestibility, nitrogen balance and blood parameters of feedlot lambs fed silages of corn grain rehydrated with water or cactus pear. Thirty male intact lambs, mixed breed, and with an average initial weight of 22 ± 4.29 kg were assigned to a completely randomized design with three treatments and ten replications. The treatments were defined as diet containing ground dry corn grain - CG (Control); diet containing corn grain silage rehydrated with water (CW) and; diet containing corn grain silage rehydrated with cactus pear (CCP). No significant differences were observed (P > 0.05) among the treatments in terms of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), total carbohydrate (TCHO), and metabolizable energy (ME). However, the ME content (P = 0.0204) of the diets containing rehydrated corn grain silage (CW) (2.57 Mcal/kg DM) was significantly higher than that of the CG diets (2.29 Mcal/kg DM). This difference in ME was associated with improved digestibility of DM (P = 0.0148), OM (P = 0.0032), and TCHO (P = 0.0027) in the CW diets. Animals fed the CG diets exhibited lower total weight gain, daily weight gain, and reduced feed efficiency. Additionally, a higher percentage of starch was found in the feces of animals consuming CG diets. In contrast, animals fed the CCP diet had higher plasma glucose concentrations (P = 0.0177). The inclusion of rehydrated corn grain silage in the diets proved to be a valuable nutritional strategy to enhance the overall nutritive value of corn grain for lambs, leading to improved animal performance. Furthermore, the utilization of cactus pear as a source of rehydration for grain silage can be particularly advantageous in regions where water resources are limited.
