The variety has short growth period. The plant grows fast. Its plant height is about 115 cm. The stem is tight，40-45 cm in length and 3-4 cm in diameter. The average fresh weight per plant is about 245 g. Its resistance to virus disease，downymildew and purple spot in field is stronger than that of the contrast 'Liaocong No.1’. It is suitable to be cultivated in short season. Its yield is about 72 t·hm-2. It is suitable for cultivation in Liaoning，Jilin and Hebei Provinces. |
