“…Total fruit weight exhibited significant, but low and negative correlations with maturation period, 100-seed weight, seed width and thickness at both levels, implying that pumpkin yields cannot be improved based on selection of these characters. The negative correlations implied that an increase in one variable would lead to a decrease in the other (Bolina et al, 2013). Mahaveer et al (2017) reported negative and significant associations of fruit yield with days to first male and female flowers.…”

Documented information on naturalized pumpkin landraces in Kenya to identify useful variability is insufficient.The present study assessed variability using quantitative characters of 155 accessions, with 70 and 85 from Kakamega and Nyeri regions, respectively. The accessions were grown in one farm in a completely randomized design with three replications. Analysis of variance showed significant (P<0.05) variation in all characters.Lowest and highest variables in mean and range were leaf length/width ratio and seed number that were 0.8 and 0.4, and 837 and 4,111, respectively. Eight factors accounted for 79.4% of total variation. The highly variable factors were fruit flesh thickness, length, width and length/width ratio, size, total weight, average weight and number, as well as seed number, 100-seeds weight, length, width, and thickness. Phenotypic coefficients of variation (PCV) were slightly higher or equal to genotypic ones (GCV). High GCV and PCV, heritability and genetic gain resulted for fruit size, total fruit weight, fruits and seeds. Over 70 positive correlations in fruit size, number and seeds with total fruit weight were observed in genotypic and phenotypic variabilities. Maximum positive direct effects on total fruit weight were observed in seeds, fruit average weight, length, and size, while indirect effects were observed in fruit number, flesh thickness, length, peduncle length and days to first flower.Multivariate analysis revealed fruit size, number, total weight, and seeds were characters of great genetic variability, which should be considered as primary components for achieving high yields in pumpkins when screening accessions for selection and improvement.

Objetivou-se realizar a caracterização de quatro acessos e duas cultivares de manjericão por características fitoquímicas do óleo essencial e botânico-agronômicas em diferentes épocas de colheita. O experimento foi instalado utilizando-se um delineamento inteiramente casualizado em esquema de parcela subdivida, com quatro repetições. As parcelas consistiram de quatro acessos e duas cultivares de manjericão e as subparcelas por cinco épocas de amostragem. A análise de agrupamento por meio do método Tocher, utilizando as características botânico-agronômicas e fitoquímicas do óleo essencial, promoveu o agrupamento dos acessos silvestres no mesmo grupo evidenciando similaridade entre eles. Os acessos coletados na mesma região formaram grupo conjuntos. Observou-se variação na constituição dos grupos pelos acessos nas diferentes épocas de avaliação por características botânico-agronômicas. A divergência genética entre acessos e cultivares de manjericão, avaliada por características botânico-agronômicas, foi influenciada pelo estádio de desenvolvimento da espécie. A localização geográfica teve influência na caracterização e avaliação da divergência genética entre os acessos. Os constituintes majoritários presentes no óleo essencial das amostras avaliadas foram o linalol, nas cultivares, e o (E)- cinamato de metila, nos acessos silvestres. Characterization botanical-agronomic and essential oil of basil accessionsAbstract: The objective of this study was to characterize four accessions and two basil cultivars by phytochemical characteristics of essential oil and botanical-agronomic in different harvest times. The experiment was installed in a completely randomized design in a subdivided plot scheme with four repetitions. The plots consisted of four accessions and two basil cultivars and the subplots for five sampling times. The grouping analysis by the method Tocher use botanical-agronomic and phytochemicals of essential oil traits, was efficient in the evaluation of genetic divergence between the accessions and cultivars of basil, as promoted the grouping of the wild accessions in the same group evidencing similarity between them. The accessions collected in the same region formed group together. Variation was observed for the group constitutions by accessions in the different sampling times by botanical-agronomical traits. The genetic divergence among basil accessions and cultivars, evaluated by botanical-agronomical traits, was influenced by development stage of specie. The geographical location influenced the characterization and evaluation of genetic divergence among accessions. The major constituents present in the essential oil of the samples were linalool, in cultivars, and (E) - methyl cinnamate in wild accessions.
