“…Therefore, these four parameters were highly correlated to one another, and are the most important determinants of fruit shelf life. These parameters also defined the first PC, and are definitive of the morphological variations observed within the pawpaw fruits, as earlier observed by Olubode et al (2016). Determination of any of these parameters, therefore, may be sufficient for drawing inferences about fruit shelf life, which is a crutial marketing parameter.…”

“…Therefore, most of the observed variation within the accessions was due to the firmness of the fruit; followed by the weight of the fruit. Much as fruit firmness is highly heritable in pawpaw (López-Gómez et al, 2009), fruit weight is highly influenced by the environment ( Olubode et al, 2016). Thus, selection of contrasting genotypes in terms of firmness would allow for selection of good performing genotypes with the desired range of quality properties.…”

Pawpaw (Carica pawpaw L.) fruit production and utilisation have been on the increase in Uganda. However, challenges related to identification of phenotypes with inherent characteristics for improvement of fruit shelf life have limited identification of better varieties. The objective of this study was to evaluate the phenotypic diversity and shelf life determinants of Uganda’s pawpaw accessions and their variations based on selected quality parameters. Nineteen accessions were collected as seeds from different markets of Uganda, germinated and planted in Namulonge-Wakiso district, central Uganda. The accessions were significantly (P<0.05) variable in terms of fruit weight parameters, with dry matter ranging from 14 - 19% and fruit weight of up to 3.9 kg; while pulp weight was up to 3.2 kg per fruit. Pulp firmness parameters were also significantly variable (P<0.05) and highly correlated with shelf life of the fruit, which ranged from 7 - 13 days depending on the accession. Fruit pulp pH ranged from 4.4-5.6; while titratable acidity of the fruit ranged from 0.03-0.08%. The accessions were clustered in four main clusters depending on the fruit firmness properties, fruit shelf life, fruit weight, pH and titratable acidity as definitive parameters. These accessions were distinguished based on morphological parameters, and henceforth defined for nutritional and economic uses. Accessions with high fruit firmness (>5 kg F) such as 16/20’ 16/16, 16/17 and 18/1; and external pulp thickness (>2 cm) such as 16/16, 16/17 and 18/1 had improved fruit shelf life and are recommended for marketability and processing.

“…Jimenes et al, [7] and Olubode et al [9], affirm that environmental factors and crop management conditions greatly influence the productive response of the papaya crop due to the direct relation with the ecophysiology and the plant metabolism. For example, air temperature and nutritional status of plants are directly related to pollinating and fixing flowers and fruit development.…”

“…There is a trend of reduced productivity as the plants show reduced leaf area [4,5]. But, these relationships may vary according to the genetic nature of the cultivar, the soil and climatic conditions and the management adopted in the crop [9]. In particular, the spatial variability and correlations of these variables in the field, as studied in other cultures [10,11,12].…”

Aims:The characterisation of the spatial variability of plants attributes associated with productivity is important for the refinement of agricultural management practices and the evaluation of the effects of agriculture on environmental quality. The objective of this research was to study the correlations of phenotypic variables, the productivity of papaya and spatial variability using a geostatistical technique. Place and Duration of Study: The research was carried out in a commercial crop of papaya (Carica papaya L.) located in the northern state of Espírito Santo, Brazil in a typical cohesive Yellow Ultisol, between June 2010 and June 2011. Methodology: The following variables were measured in each sampled plant: height of the plants (HPL); diameter of the stem at 0.20 m from the ground (SDI); lower insertion height of the first flowers (IHF); number of leaves totally open (NTL); number of flower buds (NFB); crown diameter (CRD); the height of the first fruit harvest (HFR); the total number of fruits harvested; the mass of the harvested fruit; the average number of fruits produced per plant (NFR); the average fruit mass produced per plant (kg plant -1

“…La siembra de papaya intercalada con plátano no afectó la cantidad, diámetro ni largo de los frutos. La siembra de varios cultivos que difieren en altura, desarrollo radicular y requerimientos de luz, permite un uso más eficiente de energía solar, agua y nutrientes (Olubode et al, 2016). En Nigeria, la papaya se cultiva en sistemas intercalados con plantas superiores como palma aceitera (Elaeis guineensis), plantas intermedias como cítricos y hortalizas de porte pequeño (Agboola, 2000;Olubode et al, 2012).…”
