In vitro embryo rescue culture of F1 progenies from crosses between diploid and tetraploid grape varieties
      


The percentage of planflets obtained from in-seed embryo culture of six early ripening grape eultivars and seven tetraploidy grape cultivars were 40%~71% and 52%~89%, respectively, which were more than three times higher than those from both conventional seed plantings. For eady ripening grape eultivars and tetraploidy grape cultivars embryo culturing at mature stage of fruit got significantly better results than culturing at 45 days after anthesis. Cold treatment and beak cut for cultured seeds raised the percentages...

The percentage of planflets obtained from in-seed embryo culture of six early ripening grape eultivars and seven tetraploidy grape cultivars were 40%~71% and 52%~89%, respectively, which were more than three times higher than those from both conventional seed plantings. For eady ripening grape eultivars and tetraploidy grape cultivars embryo culturing at mature stage of fruit got significantly better results than culturing at 45 days after anthesis. Cold treatment and beak cut for cultured seeds raised the percentages of embryo germination and plant formation. An effcient approach of embryo culture for early ripening grape cultivars and tetraploidy grape cultivars was made.

1988~1991年对葡萄6个早熟品种和7个四倍体品种进行种子胚培养,成苗率分别达到40%~71%和52%~89%,与常规播种相比,成苗率提高两倍以上。早熟品种和四倍体品种在浆果成熟期接种培养的效果明显地优于花后45天接种者,低温和切喙处理有效地促进了早熟和四倍体品种胚的萌发,并提高了成苗率,提出了一套早熟和四倍体葡萄品种胚培养的有效措施。

The diploid seedless grapes‘Himrod’and‘Canadice’(Vitis vinifera ×V. labrusca )were crossed with a tetraploid pollen parent‘Kyoho’(V. vinifera × V. labrusce)and the hybrid triploid plants were obtained by means of in vitro ovule culture. The rates of surviving embryos and regenerated plantlets were 3.0% ~ 8.3% and 0.5%~ 5.0%, respectively. Root tip cells of plantlets derived from diploid ×tetraploid grapes had 57 chromosomes. Ovule culture-derived plants have been established for progeny test in vineyard. Five...

The diploid seedless grapes‘Himrod’and‘Canadice’(Vitis vinifera ×V. labrusca )were crossed with a tetraploid pollen parent‘Kyoho’(V. vinifera × V. labrusce)and the hybrid triploid plants were obtained by means of in vitro ovule culture. The rates of surviving embryos and regenerated plantlets were 3.0% ~ 8.3% and 0.5%~ 5.0%, respectively. Root tip cells of plantlets derived from diploid ×tetraploid grapes had 57 chromosomes. Ovule culture-derived plants have been established for progeny test in vineyard. Five plants produced flowers in 1995, but all of them were unfruitful. Well fruitful grape clusters were obtained by treating inflorescences with 25 mg/L gibberellic acid solution at full bloom-stage and postflowering stage. Ovule culture of seedless grape can be considered as a new useful way for triploid grape breeding.

四倍体葡萄为父本,与二倍体无核葡萄杂交,取其胚珠培养获得三倍体植珠。胚珠培养的三倍体胚发育率为3.0%~8.3%,成苗率为0.5%~5.0%。根尖细胞染色体计数57条。在圃场内栽培的三倍体植株花而不稔。用GA325mg/L处理可获得良好的果穗。试验表明,无核葡萄胚珠培养是葡萄三倍体育种的一条新途径。

Two autotetraploidy grape strains, including autotetraploidy Muscat hamburg Ⅰ, autotetraploidy Muscat hamburg Ⅱ and their three successive cutting progenies were analyzed by means of detecting the characters of epidemic stomata, characters of pollen grains and chromosome number in root apex, shoot apex and tendril. The results were as follows: the histological structure in the three successive cutting progenies of autotetraploidy Muscat hamburg Ⅰ and autotetraploidy Muscat hamburg Ⅱ weren't changed; Autotetraploidy Muscat hamburg Ⅰ and autotetraploidy Muscat hamburg Ⅱ were geneticly stable.

对2个四倍体葡萄材料四玫Ⅰ及四玫Ⅱ及其连续3代的扦插株进行了表皮气孔性状和花粉粒特性观察,并对根尖、茎尖、卷须细胞进行了染色体计数。结果表明:各代植株分生组织层L1,L2和L3的倍性结构没有改变,四玫Ⅰ及四玫Ⅱ倍性稳定。
