Variation in shelf life of greenhouse-grown `Mustang' cucumber (Cucumis sativus L.) fruit was enhanced by preharvest experimental treatments of fruit thinning and fruit shading. Treatments also affected the dynamics of fruit elongation, fruit color at harvest, and chlorophyll fluorescence of the pericarp. Fruit color (grey level) at harvest, as measured by image analysis, had the highest simple (positive) correlation with shelf life. Rapid elongation and high photochemical quenching of fluorescence also characterized fruit having longer shelf life. The ability to predict cucumber yellowing is improved using a multiple regression approach, but prediction achieved by the best subset model is still too low to segregate commercially fruit having a short shelf life.

No linkage was detected in cucumber (Cucumis sativus L.) between the Cuc locus for scab resistance and the following eight morphological loci: heart leaf (hl), numerous fruit spines (ns), small fruit spines (ss), tuberculate fruit (Tu), uniform immature fruit color (u), dull fruit epidermis (D), gynoecious sex expression (F), and delayed flowering (df). All nine traits were monogenically inherited.

difficult ( Fang et al., 2016 ; Huang and Lin, 2008 ). The balance between the two pigments determines the fruit color ( Jamaludin et al., 2010 ; Phebe et al., 2009 ). In recent years, C* (chroma) and h° have been used as indicators of pitaya fruit color

Fruit of 34 peach (Prunus persica L. Batsch). cultivars were harvested at maturity and visually evaluated by panelists on a 1 to 10 scale, where 10 = excellent color. CIELAB coordinates (L* a* b*) of fruit color were measured at the midpoint between the stem and the calyx end with a Minolta CR-200b calorimeter on the blushed and ground areas of each fruit. Simple linear regressions of color coordinates with panel ratings indicated that blush chroma, blush L*, blush hue angle and E* (total color difference between ground and blush) all influence visual color evaluation. Not only does assessing fruit color with a calorimeter permit color to be reported in internationally accepted units, but the relationships indicate that instrumental values relate well to qualitative ratings.
