O feijoeiro é uma das principais culturas do país, e o Estado de Minas Gerais é um dos maiores produtores, representando cerca de 15% da produção nacional. O objetivo deste trabalho foi testar o desempenho de linhagens de feijoeiro comum cultivadas nas épocas das águas e do inverno, na região do Triângulo Mineiro, Minas Gerais. No cultivo das águas (semeadura em dezembro de 2005) e do inverno (semeadura em maio de 2006), as linhagens/cultivares testadas foram BRS Horizonte, CNFC 8059, CNFC 8065, CNFC 8075, VC-6, VC-7, VC-8, VC-9, VC-10, VC-11, VC-12, CNFC 10443, CNFC 10453, CNFC 10476, MA-I-2.5, MA-I-8.9, MA-I-18.13, RC-I-8, CV-46, CV-55 e Z-22, além das testemunhas BRSMG Majestoso, Pérola e BRSMG Talismã e VC-3. Em cada experimento, o delineamento experimental foi o de blocos casualizados com 25 tratamentos, em três repetições, a parcela útil foi de 4 m². No cultivo das águas, os rendimentos das linhagens mais produtivas variaram entre 2,69 e 2,78 t ha-1 (VC-9 e VC-10, respectivamente) e, no inverno, alcançaram 3 t ha-1 (3,01 e 3,00 t ha-1, CNFC 8065 e Z-22, respectivamente). De maneira geral, as linhagens foram mais produtivas no cultivo do inverno, embora a interação entre linhagens e época de cultivo tenha indicado desempenho distinto entre elas em relação à época. |

Understanding vulnerabilities of plant populations to climate change could help preserve their biodiversity and reveal new elite parents for future breeding programmes. To this end, landscape genomics is a useful approach for assessing putative adaptations to future climatic conditions, especially in long-lived species such as trees. We conducted a population genomics study of 207 Coffea canephora trees from seven forests along different climate gradients in Uganda. For this, we sequenced 323 candidate genes involved in key metabolic and defence pathways in coffee. Seventy-one single nucleotide polymorphisms (SNPs) were found to be significantly associated with bioclimatic variables, and were thereby considered as putatively adaptive loci. These SNPs were linked to key candidate genes, including transcription factors, like DREB-like and MYB family genes controlling plant responses to abiotic stresses, as well as other genes of organoleptic interest, such as the DXMT gene involved in caffeine biosynthesis and a putative pest repellent. These climate-associated genetic markers were used to compute genetic offsets, predicting population responses to future climatic conditions based on local climate change forecasts. Using these measures of maladaptation to future conditions, substantial levels of genetic differentiation between present and future diversity were estimated for all populations and scenarios considered. The populations from the forests Zoka and Budongo, in the northernmost zone of Uganda, appeared to have the lowest genetic offsets under all predicted climate change patterns, while populations from Kalangala and Mabira, in the Lake Victoria region, exhibited the highest genetic offsets. The potential of these findings in terms of ex situ conservation strategies are discussed.
