Innovating in the Technique System of Embryo Rescue of Stenospermocarpic Grape and Breeding New Cultivars of Both Seedless and Disease-resistance Traits
Seedless grapes are one of the principle objectives of grape breeding in the world. Zygotic embryos of seedless grapes can’t develop normal seeds because of abortion, so seedless grape cultivars are only taken as paternal parents in breeding new seedless grapes by conventional crossing, but the seedless progeny is only 0 to 15.9%. By embryo rescue technique, seedless×seedless crosses have produced 45% to 82% seedless offspring, but most of them are susceptible to diseases. Hybridization of seedless grapes a...
