一、培育经过和示范推广情况:我们在1979年,用郑州市蔬菜研究所选育的“早黑叶 ms”作母本和洛阳市农业科学研究所提纯的“石特自交系”作父本进行杂交。通过繁育亲本,试配杂交组合,测定组合力大小,品种对比试验、示范和推广等一系列工作,证明“早黑叶 ms×石特自交系。是一个稳产高产,抗逆性强,适应性广,品质好,净菜率高的优良杂交种,深受
First, to cultivate and promote the situation through the demonstration and demonstration: In 1979, we Zhengzhou City Vegetable Research Institute breeding “black leaf ms” as the mother and Luoyang Institute of Agricultural Sciences purified “stone inbred line” as the father This hybridization. Through a series of work such as breeding parents, crossing hybrid combinations, determining the size of combinatorial forces, comparing and experimenting with varieties, demonstrating and popularizing, it proves that "early black leaf ms × Shi Te inbred line is a stable yield and high yield, Wide range of sexual, good quality, high net rate of excellent hybrids, by
