Molecular markers detect stable genomic regions underlying tomato fruit shelf life and weight

Abstract

-Incorporating wild germplasm such as S. pimpinellifolium is an

QTL detection for fruit shelf life and quality traits across segregating populations of tomato

“…Finally, the cultivated alleles in a QTL on chromosome 1, prolonged the fruit shelf life (Table 5E). These results demonstrate the presence of favorable alleles for this trait in the cultivated genotype as it has been previously reported by Pratta et al (2011).…”

Genome-wide expression analysis at three fruit ripening stages for tomato genotypes differing in fruit shelf life

“…However, LA1385 and NOR had the longest fruit shelf life suggesting that firmness is not directly related with fruit shelf life in this genetic background. These results have a great coincidence with previous studies (Pereira da Costa et al, 2009;Rodríguez et al, 2010;Pratta et al, 2011a), but some differences in the mean values for each trait can be explained by a genotype by environmental interaction (G × E) affecting fruit traits in tomato (Pratta et al, 2011b;Panthee et al, 2012). Regarding to the period MG to B, NOR showed the highest mean value for it but there is not significant differences between the wild genotypes in this period.…”

The effect of covering material on the yield, quality and chemical composition of greenhouse‐grown tomato fruit

“…However, total yield showed significant differences among the studied cover materials. According to Pratta et al, 25 fruit weight is not dependent on growth conditions and is considered a yield parameter that is highly affected by genotype, fruit load and competition between fruit and leaves for biosynthetic assimilates. 26 Considering that in our study clusters of fruit were thinned to the same fruit number (5 fruits truss −1 ), this could explain the insignificant effect of cover material and harvest date on fruit size.…”
