seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. therefore, marker-assisted selection (mas) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. in ...

Abstract Pierce’s disease is a deadly of grapevines caused by the bacterial pathogen Xylella fastidiosa (Xf). A resistance locus from Vitis arizonica/candicans b43-17 segregated as single dominant gene and mapped PdR1a PdR1b in two F1 sibling selections. The physical mapping allele allowed identification five ORFs Leucine-Rich Repeat Receptor Kinase family. Two ORFs: V.ari-RGA14 V.ari-RGA18 wer...

Antioxidant potency of Indian grape cultivars varying in their skin color, seed and polyphenol content (Bangalore blue, Pandhari sahebi, Sharad seedless and Thompson seedless) and their components (whole grapes, pulp with skin and seeds) was examined as 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity using electron spin resonance spectrometry. The total polyphenols in Indian g...

Seedless triploid watermelons have increased in popularity since the early 1990s, and the demand for seedless fruit is on the rise. Sweetness and sugars are crucial breeding focuses for fruit quality. Volatiles also play an important role; yet, we found no literature for seedless varieties and no reports using solid-phase microextraction (SPME) in watermelon. The objective of this experiment wa...
