一、选育经过 1987年选育早熟、丰产、瓜条性质好的81—1—1—3株系为父本,以第一雌花节位低,连续着生性强的83—8雌性系为母本,试配组合,1988——1991年在田间进行杂交组合鉴定及品比试验,连续表现早熟、高产、瓜条性状好.明显超过当时主要栽培品种长春密刺。 二、试验结果 1.早熟性 第一雌花节位低,前期产量高是衡量早熟性的重要标准,“853“黄瓜的第一雌花节位平均3—4节,连续着生数朵雌花,比长春密刺低0.4节,在四年品比试验和92、93两年省区试中,前期产量为1210.61—1594.96kg/亩.分别比对照长春密刺增产12.91%、7.36%。
First, the breeding After 1987 breeding precocious, high yield, good quality of the melon strips 81-1-1-3 lines as the male parent to the first female flower node is low, continuous and strong sexual 83-8 female line is Female parent, test combination, 1988 - 1991 hybrid combinations in the field identification and ratio test, continuous performance of early maturity, high yield, good characteristics of the gourd, significantly more than the main cultivated varieties of Changchun at the time. Second, the test results 1. Premature First female flower node is low, pre-high yield is an important measure of precocity, ”853 " cucumber, the first female flower node average 3-4 sections, Compared with Changchun, the yield was 1210.61-1594.96kg / mu in four-year trial and 92,93 years of provincial trial, respectively, which increased 12.91% and 7.36% respectively compared with the control.
