| 摘 要： | 以SLA、RQA、CRA等 3个人工四倍体茄子种群为基础 ,以群体内半同胞家系选择和群体间轮回聚合选择相结合 ,露地栽培和大棚保护地栽培生境选择相结合 ,历经近 2 0年 ,育成了第 1个人工同源四倍体 (2n =4 8)茄子品种新茄一号。该品种平均单果种子数 32 4粒 ,为二倍体品种六叶茄的 9.5 % ;果肉细嫩 ,粗纤维少 (- 17.2 2 % ) ;糖酸比高 ,生食无酸涩味 ,风味佳 ,适于生食、熟食及加工制干。果实Vc、脂肪、蛋白质含量分别较对照二倍体品种增加了 74 .38%、31.30 %和 34.2 2 %。新茄一号适应性强 ,适当早播 ,产量一般可达 6 75 90 .9kg/ha以上 ,总产量接近和高于 2个二倍体对照品种 ,早熟性及早期产量优于CK1圆形红茄 ;较CK2 六叶茄稍差。新茄一号为少籽高营养茄子品种 ,具有广阔的应用前景

| Abstract: | The breeding work began in 1997 using SLA, RQA and CRA, which are all tetraploid eggplants, as experimental materials. Methodology utilized recurrent half sib selection and recurrent convergent cross selection of inter population, planting both in open field and plastic shed. This new variety has fewer seeds in its fruits (the average number of seed per fruit is 324, only 9.5% of those in diploid cv.Liuyeqie), delicate pulp, few crude fibres (-17.22%), high suger acid ratio, and no sour or puckery taste. It is suitable to eat raw, cooked or processed. In contrast with diploid, Vc content increased 74.38%, fat increased 31.30%, and protein increased 34.22 % cv.Xinqie No 1 is highly adaptable and can be sowed a little earlier. The average yield per ha is 67 590.90 kg or more; the total yield is equal to or a little higher than dipoid. It can be harvested earlier than CK 1 cv. Yuanxinhongqie, but later than CK 2 cv. Liuyeqie. It is a rare variety with few seeds and high in nutrition, so it has a boundless prospect. |
