早丰一号辣椒足保护地栽培的优良组合。为提高其一代杂种的质量和产量,在制种技术上应抓好下列几个问题: 一、重视亲本的提纯和保纯早丰一号母本系南京早椒;父本为上海甜椒。近年由于亲本混杂退化,致使一代杂种种植后在植株高矮、熟性早迟、果实大小和产量高低等方面都有一定差异。为此必须重视对亲本进行选择和繁育。母本应选株高30—35厘米、分枝多、叶狭小、色深绿、主茎6—7节现蕾、果长、近似灯笼形、青椒深绿色的植株;父本需选株高60—65厘米、分枝少、叶宽厚、色深绿、主茎12—14节现蕾、果大、灯笼形、果顶具4个凸起,青椒深绿色的株型。凡优良单株可采用混合选择法;有条件者,最好采用单株选择法。由于辣椒为白花授粉易发生异交作物,异花结实率高达10%, Zao Feng chili peppers enough to protect the excellent combination of cultivation. In order to improve the quality and yield of the hybrids of its first generation, the following several problems should be grasped in the seed production technology: First, attention should be paid to the purification and preservation of the parent ZF No.1’s parents should be Nanjing Zaojiao; In recent years, due to the mixed degradation of parents, resulting in a generation of hybrids in plant height, late maturity, fruit size and yield levels have some differences. Therefore, we must attach great importance to the selection and breeding of parents. Mother should be selected plant height of 30-35 cm, branches and more, leaves narrow, dark green, main stem 6-7 buds, fruit long, approximate lantern-shaped, dark green pepper plants; 60-65 cm, fewer branches, leaves generous, dark green, the main stem 12-14 section of budding, large fruit, lantern-shaped, fruit top with four raised green pepper dark green plant type. Where excellent single plant can be mixed selection method; conditional, the best single plant selection method. As pepper is prone to cross pollination of white flowers, cross-stature rate as high as 10%
