- 摘要:
- “泰香2号”是以“姜堰香”丝瓜为材料，通过系统选育法连续6代自交选育而成的丝瓜新品种。该品种早熟耐褐变，春季栽培从出苗到第1朵雌花开放时间约58 d。植株连续坐果能力强，主蔓第1雌花节位7～8节上下。果实绿色，圆筒状，果皮光滑，瓜条匀直；肉质嫩滑，有清香味；种皮颜色黑色。果实纵径23～28 cm，横径4.0～4.5 cm，单瓜质量约280.0 g，667 m2产量约4 149.9 kg。总糖含量35.05 mg·g-1，维生素C含量6.19 mg·（100g）-1，过氧化氢酶（CAT）活性72.29 U·g-1。产量高，商品性好，抗逆性强，耐贮运，田间抗霜霉病和黄瓜花叶病毒病。适宜江苏省及生态条件相似地区春秋两季露地或设施栽培。
- Abstract:
- ‘Taixiang No.2’ is a new loofah variety selected from ‘Jiangyanxiang’ luffa variety through systematic breeding method for six consecutive years.It is early maturing and flesh browning tolerant.The cultivation period lasts about 58 days from seedlings to the opening of the first female flower in spring.It has a strong plant growth potential and continuous fruit setting ability.The first female flower and setting fruit appear approximately at 7th-8th node of the main vine respectively.The fruit is cylindrical in shape，green and smooth in skin，straight and uniform in stems，and sweet and fragrant in smell.The color of the seed coat is black.The longitudinal and transverse diameter of its fruit is 23-28 cm and 4.0-4.5 cm correspondingly.The single fruit mass is about 280.0 g and the yield per 667 m2 is about 4 149.9 kg.The total sugar content is 35.05 mg·g-1，and vitamin C content is 6.19 mg·（100g）-1，and CAT activity is 72.29 U·g-1.The variety has high yield and commercial performance，excellent storage and transportation quality，and field resistance to downy mildew and cucumber mosaic virus.It is suitable for the cultivation under greenhouses in early spring and autumn or open field both in Jiangsu Province and similar ecological areas.
