| Abstract In order to obtain twenty-one evaluated accessions from the Avocado Germplasm Bank of CORPOICA, Palmira Research Station with two pathogenic strains of the oomycete, Phytophthora cinnamomi Rands. The aim of this research was to identify avocado accessions, which used as rootstocks in a cultural control strategy for preventing root rot disease. Disease progression was evaluated using mycelium of the pathogen by cut-stem inoculation. The measurements of symptom progression length and width were carried out and analyzed. In order to obtain the area under the disease progression curve (AUDPC), these data were analyzed. A randomized complete block design (RCBD), with a factorial design of 3 x 21 in-subdivided parcels (2 strains of the pathogen, a... |

| Abstract Tepary bean, Phaseolus acutifolius A. Gray, is tolerant to drought and high temperatures but has low genetic diversity in its cultivated forms. To increase this diversity, a research program on mutation induction was initiated. The aim of this study was to establish the effect of different agro-morpho-physiological parameters on pollen viability and quantity in 123 mutant lines M5 of P. acutifolius and parental genotypes, by processing micrographs of pollen stained with acetocarmine. The experiment was conducted under greenhouse conditions and the experimental design was a split-split plot with three replicates; in addition, the factors evaluated were as follows: soil moisture conditions, inoculation with Bradyrhizobium sp. or Rhizobium tropici,... |
