The ability to avoid self-pollination is a trait that evolved as a manner of reducing the deleterious effects of inbreeding in various allogamous plant species, including Coffea canephora. The aim of this study was to perform directed hybridizations to characterize the compatibility groups of superior C. canephora clones, since plant selection can reduce variability for this trait. For that purpose, directed hybridizations were carried out in cross arrangements using a balanced diallel without self-fertilization and without reciprocals. The genotypes evaluated were derived from open pollination and from directed hybridizations using Encapa03 as a male parent donor of pollen grains and Robusta640, Robusta 2258, and Robusta1675 as female parent receptors of pollen grains. To control the occurrence of type I and type II errors, the likelihood ratio test was used. Compatible crosses were predominant (73.7%). Compatible crosses exhibited a mean rate of fruit set of 44%, with amplitude from 26% to 77%. Of the total of 80 crosses performed, three crosses exhibited unexpected results according to the grouping proposed (P08 x P16, P09 x P15, P09 x P16). From the degree of kinship, the genealogy of the S gene and the segregation of the alleles from one generation to another was estimated. The genotypes P12, P14, and P10 exhibited the highest estimates of LOD score associated with their clustering in groups I, II, and III. These genotypes may be used as tester plants of their compatibility groups MenosThe ability to avoid self-pollination is a trait that evolved as a manner of reducing the deleterious effects of inbreeding in various allogamous plant species, including Coffea canephora.

O objetivo com este trabalho foi avaliar o efeito das malhas coloridas no teor relativo de clorofila e no desenvolvimento inicial de Piper tuberculatum Jacq. A unidade propagativa foi semeada em bandejas de 200 células contendo substrato orgânico comercial e mantidas em ambientes recobertos com malhas vermelhas, pretas e azuis, com 80% de sombreamento e avaliadas após 57 dias. Na malha preta as plantas estiolaram, com maior investimento no crescimento apical do caule. A malha vermelha proporcionou o maior desenvolvimento foliar, teor relativo de clorofila, diâmetro do caule e volume radicular, podendo ser considerado o melhor ambiente para o desenvolvimento de P. tuberculatum. |
