甜椒杂种优势较强,优良的杂交组合一般比亲本增产30—40%以上。但由于甜椒为常异花授粉作物,制种时需要进行人工去雄授粉,而且在一般的露地栽培条件下,虽然每一株植株上可以出现几百个花蕾,开放几十朵花,但每株平均结果数仅有六、七个,自然落花率高达80—90%。因此,制种比较困难。近年来,我们在选育优良杂交组合的同时,还开展了制种技术的研究。试验结果表明只要掌握其开花座果习性,采用正确的制种技术,则可以大大提高座果率,增加种子产量,降低生产成本。
Sweet pepper hybrid heterosis, excellent hybrid combinations generally yield more than 30-40% more than the parent. However, since the sweet pepper is an evergreen pollination crop, it is necessary to manually de-poll the seed when it is planted, and under the condition of the general open-field cultivation, although hundreds of flower buds and dozens of flowers may appear on each plant, The average number of results per plant is only six or seven, the natural rate of falling as high as 80-90%. Therefore, seed production is more difficult. In recent years, we have also carried out research on seed production techniques while breeding excellent hybrid combinations. The results showed that as long as the mastery of its flowering fruit habits, the use of the right seed production technology, you can greatly increase the rate of fruit set, increase seed yield, reduce production costs.
