我省春季露地栽培的番茄产量较低,1982年平均亩产仅2,700斤左右。其原因除与栽培技术及病虫防治有关外,主要是缺少高产优质的新品种。1983年,我们在参与全国鲜食番茄品种区域试验中发现,有些品种比我省目前普遍栽培的强力米寿品种增产潜力大。现将这些优良品种(系)的特征、特性简介如下,供引种参考。 苏抗四号 江苏省农科院蔬菜研究所育成,组合为矮黄×524。植株自封顶,长势旺,适应性较强,适于春季露地栽培。第一花序坐果率为81％,全株三穗平均达65.7％。对病毒病和晚疫病(病情指数39.4％)都属耐病型。果红色,单果重112克。可溶性固形物为3.7％,品质中等,亩产8.900斤。 丽春 中国农科院蔬菜所配制的早粉2号×农大24号组合,经多代系选成的稳定品种。无限生长类型,节间较短,坐果力强。露地栽培第一花 The yield of tomato grown in open field in spring in our province is relatively low, only about 2,700 kg per mu in 1982. In addition to the reasons for its cultivation techniques and pest control, the main is the lack of high yield and quality of new varieties. In 1983, we participated in the national trials of fresh tomato varieties found in the region, some varieties than the province now widely cultivated varieties of strong rice longevity potential. Now these fine varieties (lines) features, characteristics are as follows, for the introduction of reference. Sukang No. 4 Jiangsu Academy of Agricultural Sciences Institute of Vegetable bred, the combination of short yellow × 524. Plant self-captive, prosperous, adaptable, suitable for spring open field cultivation. The first inflorescence fruit setting rate of 81%, the whole plant three spikes an average of 65.7%. Virus disease and late blight (disease index 39.4%) are resistant to disease. Fruit red, single fruit weight 112 grams. Soluble solids of 3.7%, medium quality, 8.900 kg per mu. Lai Chun Chinese Academy of Agricultural Sciences prepared by the early vegetable No. 2 × Nongda No. 24 combinations, selected by the multi-generational strains of stable varieties. Unlimited growth type, shorter internodes, strong fruit set. Exposed to cultivate the first flower
