近年引进的大花矮牵牛已普及各地,由于它花朵大,花色艳,花期长,株形矮,适应性强,深受大家喜爱。但不少地方在培育过程中是用白花授粉结种的种子来育苗的,用这种方法培育的大花矮牵牛将变劣和退化,这个问题应引起重视。我们要利用“杂种优势”选择优良亲本以人工授粉杂交来育种,用一代杂交种来育苗,只有这样才能使大花矮牵牛越种越好。杂交育种首先要选定有优良性状的亲本,要求有杆矮、花大、色艳、型美、勤花、多花、健壮抗病
In recent years, the introduction of big flower petunia has spread throughout the country, because of its flowers, flowers Yan, long flowering period, short plant shape, strong adaptability, by everyone’s favorite. However, in many parts of the cultivation process, seedlings are pollinated with white flowers and the petunias cultivated by this method will deteriorate and degenerate. This issue deserves our attention. We want to use the “heterosis” to choose the best parents to artificial breeding by artificial pollination, with a generation of hybrid seedlings, the only way to make big flower Petunia better. First of all, hybrid breeding should be selected with good traits of parents, requiring a short bar, flowers, color Yan, type beauty, ground flowers, flowers, robust disease resistance
