辣椒一代杂交种具有显著的增产优势,一般可比主栽品种增产20～50％,甚至一倍以上。目前大面积推广的南京黑壳早椒×上海茄门甜椒具有早熟、高产、抗病、质好、适应性广等特点。但是种子产量低,大棚内制种一般为30公斤/亩,最低的仅15公斤/亩。徐州市奎山乡科技站,1984年制种产量达60公斤/亩,且杂交率在95％以上;1985年制种产量达67.25公斤/亩,居全省之首。目前对蔬菜
Pepper generation hybrids have significant yield advantage, generally 20 ~ 50% increase than the main varieties, or even more than doubled. At present, large-scale promotion of Nanjing black shell pepper × Shanghai eggplant bell pepper with early maturity, high yield, disease resistance, good quality, wide adaptability and so on. However, the seed yield is low. The seed production in the greenhouse is generally 30 kg / mu and the lowest is only 15 kg / mu. Xuzhou Kuishan Township Science and Technology Station, 1984 seed production reached 60 kg / mu, and the hybridization rate of 95% or more; 1985 seed production reached 67.25 kg / mu, ranking first in the province.
