“…With the aid of mechanical, quantitative evaluation of fruit texture traits, we were successfully able to estimate the GCA and SCA effects of cucumber fruit texture traits and to clarify their contributions to F 1 hybrid performance by means of diallel analysis. Peterson et al (1978) reported that the fruit firmness of cucumber was quantitatively inherited, with strong additive genetic effects. The highly significant GCA effects on placenta and flesh firmness observed here also indicate the importance of additive genetic variance in the transmission of parental fruit firmness to progeny.…”

Traits that contribute to fruit texture are important targets for genetic improvement in cucumber, and the knowledge of the combining abilities of parental genotypes is crucial to conducting systematic breeding of new F 1 hybrid cultivars that possess a desired fruit texture. We estimated the general combining ability (GCA) and specific combining ability (SCA) of fruit texture traits related to fruit firmness and crispness. We produced a diallel set of 28 F 1 hybrids by crossing eight cucumber genotypes in a half-diallel mating design. We obtained quantitative scores of fruit texture by means of mechanical measurement and analyzed them by Griffing's combining ability analysis to estimate the GCA and SCA effects of the parental genotypes. The GCA effect was of more significance than the SCA effect in determining hybrid performance. Estimates of the GCA effects were highly significant for most parental genotypes and were highly correlated with actual performance of parental genotypes. Because of this close correlation between GCA effect and actual fruit texture traits exhibited by the parents, we demonstrated that all traits could be effectively pre-selected at the level of parental genotype.

“…Thus, many researchers have sought to obtain an appropriate understanding of the genetic and physiological mechanisms that govern texture (Jones et al 1954, Goffinet 1977, Peterson et al 1978, Kanno and Kamimura 1980, Suojala-Ahlfors 2005, Sakata et al 2008. Breeding efforts to improve fruit texture, although somewhat successful, have been based largely on rough, qualitative evaluations of fruit texture.…”

Fruit crispness is of great importance in cucumber as well as in other fruit vegetables, because it relates directly to the commercial value of the product. In breeding projects and pre-or postharvest studies of fruit texture, an effective quantification method has been desired to replace rough, qualitative evaluations of fruit texture based solely on human perceptions. We applied several analytical methods to the force-deformation curve to quantify cucumber fruit crispness and assessed the efficacy of these methods as candidate cucumber fruit crispness indicators for use in breeding or research. Texture parameters for the flesh and placenta of 12 cucumber cultivars, based on the crispness index, apparent fractal dimension, and power spectrum and peak analyses, were calculated from mechanical measurement results. There was a significant large genotypic (cultivar) effect on the texture parameter values and a lesser, but still significant, contribution from the environment. Furthermore, we found strong relationships between these texture parameters and sensory crispness. These results indicate that these methods for analyzing the force-deformation curve provide effective, quantitative indicators of fruit crispness, with considerable promise for application in scientific research and breeding programs.

“…Breeders have hitherto assessed fruit texture traits by sensory evaluation. Genotypic effects and heritability of fruit rmness have been investigated in crossing experiments, and it has been suggested that rmness is controlled genetically (Peterson et al 1978;Kanno and Kamimura 1980;Yoshioka et al 2009Yoshioka et al , 2010. However, few genetic studies of fruit crispness in cucumber have been performed (Yoshioka et al 2009(Yoshioka et al , 2010.…”

“…In breeding programs, the genetic structure of the breeding materials and the inheritance of target traits are important for e cient breeding. The genetic and physiological mechanisms of fruit texture traits have been investigated by many researchers (Jones 1954;Go net 1977;Peterson et al 1978; Kanno and Kamimura 1980;Suojala-Ahlfors 2005;Yoshioka et al 2010;Sakata et al 2011;Shimomura et al 2016). Although breeding efforts for many fruit vegetables have focused on improvement in texture, few advances have been made in identi cation of genetic mechanisms, because aspects of texture other than rmness are di cult to measure quantitatively.…”

Quantitative trait locus analysis of cucumber fruit texture using double‐digest restriction‐site‐associated DNA sequencing

Fruit rmness and crispness are important traits of cucumber because they directly affect its commercial value. We performed quantitative trait locus (QTL) analysis of these fruit texture traits with the double-digest restriction-site-associated DNA sequencing (ddRAD-Seq) technique and detected 31 QTLs for fruit rmness: 11 for placenta rmness, 12 for skin rmness, and 8 for esh rmness; and 25 QTLs for crispness-related scores: 10 for esh crispness index, 8 for esh apparent fractal dimension by Richardson plot, and 7 for esh apparent fractal dimension by box-counting (Kolmogorov's dimension). Several QTLs associated with esh rmness and crispness are located near regions for fruit length, diameter, and length-to-diameter ratio, and for resistance to powdery mildew and downy mildew, indicating that gene linkage is likely to limit breeding e ciency. Our results will contribute to the development of informative DNA markers closely linked to genes for desirable fruit texture traits that are required for effective selection of new cultivars.
