黄瓜为异花授粉作物,在生产过程中容易混杂退化,为此进行提纯复壮尤其重要。 一、选种 (一)选种标准 根据原品种的熟性、抗性、株型、叶型、雌花节位、雌花节率;瓜条色泽,刺瘤颜色和稀密、花顶大小、心室、肉厚、品质;种瓜长短、颜色、网纹,籽粒形状、大小等主要性状进行选种。 (二)选种方法 设塑料大棚(或温室)选种圃。于苗期、结瓜期、成熟期进行选种。苗期选择生长势强的壮苗,具原品种的叶型、节长的单株50—100株,挂牌。在苗期选种基础上,着重初花期、雌花节位、雌花节率,瓜型和色泽,刺瘤颜色稀密、瓜把长短,熟性、抗病性,选择优良单株。在瓜期选择基础上根据该品种的种瓜形状、长短、颜色、网纹进行选择,按单株单瓜编号采种。
Cucumber is cross-pollination crops, easy to degenerate in the production process degradation, for this is particularly important purification and rejuvenation. First, the selection of species (A) selection criteria According to the original varieties of maturity, resistance, plant type, leaf type, female flower node, female flower node rate; melon color, , Flesh, quality; species length, color, texture, grain shape, size and other major traits selection. (B) selection method Plastic greenhouse (or greenhouse) selection of nurseries. At seedling stage, fruiting stage, mature stage selection. Seedling growth strong selection of strong seedlings, with the original varieties of leaf type, length of the plant 50-100 strains, listed. Based on the selection of seedling stage, focus on the early flowering stage, the female flower node, the female flower node rate, melon type and color, broccoli color density, melon length, maturity, disease resistance, choose a fine plant. Based on the selection of melon seeds, the varieties of melon according to the shape, length, color, texture selection, according to the single plant number of melon seeds.
