耐盐番茄东科1号和东科2号的选育

耐盐番茄东科1号、东科2号是通过野生耐盐番茄契斯曼与粤农2号远缘杂交,从杂交后代与耐盐亲本多代回交的多个材料里经系统选育而成。两者均为小果型,东科1号果圆形,平均单果质量15g,耐低温,耐盐,土壤含盐量0.7%以下生长正常;东科2号果柱形,平均单果质量20g,耐盐,土壤含盐量0.8%以下生长正常。两者均较抗叶霉病、灰霉病,在土壤含盐量0.5%以下的保护地设施栽培每667m2产量8000~10000kg。

Tow New Salt-tolerance Tomato Varieties-‘Dongke No.1’ and ‘Dongke No.2’

Dongke No.1 and Dongke No.2 were developed through Yuenong No.2 crossing wild tomato Qisiman with tolerance to salt and system selection. Both have small fruits and average fruit weight is 15-20 g. Both are tolerance to low temperature and salt under the salt level of 0.7 %-0.8 %, are resistant to Cladosporium fulvum and gray mould, and yield 120-150 t·hm -2 under protected cultivation with soil salt content of less than 0.5 %.
