ABSTRACT.
Paspalum notatum is a subtropical grass present throughout America, and one of the main constituents of the natural grasslands in Uruguay. An
apomictic autotetraploid (2n = 4x = 40) is the most frequent cytotype. The occurrence of sexual diploids (2n = 2x = 20) has also been reported as well as the occasional presence of apomictic triploids and pentaploids in Argentina. In this study, ISSR (inter simple sequence repeats) molecular markers were used to analyze the genetic variability of 210 P. notatum individuals from a collection from Uruguay. Cytometric analyses and chromosome counts were used to assess the ploidy level of the individuals. All plants from Uruguay analyzed were tetraploid. Intra- and inter-population variability was found both in genomic DNA content and at the genotypic level. Several multilocus genotypes were shared among individuals within populations and among populations over moderate geographical ranges, at the same time, very dissimilar genotypes were found within the same population. Part of the genetic variance among populations can be explained by a broader scale geographic structure which is partly coincident with the traditionally recognized grassland management regions. In spite of the apparently high degree of genetic admixture within populations, groups of related genotypes seem to follow a broader geographical structure in the area under study. These results suggest that an efficient collection strategy for this apomictically reproducing species should include carefully planned intra- and inter-population sampling. A broader scale regional sampling strategy should also be considered although further studies will be required to define genetic structure at this level.

ABSTRACT.
Feijoa (Acca sellowiana (Berg.) Burret) is one of the most popular native Uruguayan trees whose functional characteristics have attracted the interest for commercial cultivation. The aim of this work was to evaluate the postharvest behavior of six genetic materials, identified as 95, 97, 98, 152, 153 and 154 from the Facultad de Agronomía and Instituto Nacional de Investigación Agropecuaria (INIA, Uruguay) breeding program. Fruits harvested at two maturity stages (M1: not easily picked; M2: touch picking) were stored for 0, 15 and 30 days at 5°C and 95% relative humidity (RH) plus 7 days at 18°C (shelf life). Respiration rates and ethylene emissions were measured every 3 days, while flesh firmness, weight loss and total polyphenol content were evaluated at the end of the storage period and during shelf life. The respiration rate of all the genetic materials was around 27.6 mg kg-1 h-1 of CO2 during the storage period, while ethylene emission was maintained below 100 µL kg-1 h-1 without differences among maturity stages and genetic materials. Fruits harvested at the M1 stage were 40-60% more firm than fruits harvested at the M2 stage. Genetic materials identified as 95 and 98 had the highest firmness results, with values of 150.1 and 145.1 N (M1), 112.6 and 90.4 N (M2) at harvest and 28.8 and 17.4 N (M1) and 17.2 and 15.4 N (M2) after 30 days at 5°C + 7 days at 20°C, respectively. Average weight loss at the end of storage (30+7) was 14.7%. Fruits identified as material 152 had the highest polyphenol content with values at harvest of 2,384.5 mg GAE 100 g-1 DW (M1) and 2,130.7 mg GAE 100 g-1 DW (M2). At the end of the storage period (30+7), total polyphenol contents decreased between 30-70% in the M1 stage and between 20-50% in the M2 stage. Materials 95, 98 and 152 are interesting for commercial production due to their firmness retention and their functional composition.
