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 Based on three artificial tetraploid eggplant populations, such as SLA, RQA and CRA, the selection of half-sib families in population and the combination of recurrent colonization in populations were combined. The combination of open-field cultivation and selection of planting habitats in greenhouses protected areas, Year, bred the first artificial autotetraploid (2n = 48) eggplant variety Xindaoliang. The average number of seeds per plant was 32 4, which was 9.5% of the diploid variety Six-leaf tomato; the pulp was tender and the crude fiber was less (- 17.2 2%); the ratio of sugar and acid was high; the raw food had no astringent taste and good flavor; Raw food, cooked food and processing dry. Fruit Vc, fat and protein content increased by 74.38%, 31.30% and 34.22% respectively compared with the control diploid. New tomato one strong adaptability, suitable for early sowing, the yield generally up to 6 75 90 .9kg / ha or more, the total output close to and higher than 2 diploid control varieties, early maturity and early yield is better than CK1 round red Solanum; slightly worse than the CK6 six-leaf tomato. New eggplant for the first few high-nutrition eggplant varieties, has broad application prospects
