Vinson Ltd : Everest, Evie, Eve’s Delight, Sweet Eve -Plant Sciences : Arabella, Prize, Triumph

Rumba -Fresh Forward -Alternative for Honeoye/Clery -Early ripening -For wholesale market -Conical berries with gloss and good fruit shape/set -High chilling requierement

Rumba -High fruit weight -Glossy after storage -Firmness and taste average rating -Colour is bright red and not as purple after picking as Clery and Honeoye

Rumba -Compact strong planttype -Strong petioles -Long flowertrusses -Easy picking -Strawberries click off easily

Rumba -High yielding with a continuous long productioncycle -A few days later than Clery but a longer extended harvestperiod

Rumba Not susceptible for rootdiseases Not susceptible for mildew (oidium) Not much Botrytis

Rumba -no special nutritional needs -risk is to high boron in water/soil <<leafnecrosis <<flowerabortion <<smaller fruit and dry calyx <<Low boron fertilsing, maxl 60 ppm in leaves max 20 µmol/l=0. 2 mg/l in Wat

Allegro (FF 1602) -Early variety -2 days after Clery -higher fruit weight and yield : + 20 %

Allegro -Vigorous with long flower trusses -Needs less nitrogen -Flowers under canopy and less susceptible to night frost -Well suited for covering with fleece or rowcover

FF 1602 Clery

Allegro +Uniform fruit size on average 20 gram +Conical fruits +first fruits can be ridged + can have a neck in rain periods

Allegro +Bright red colour of fruits +Good firmness +Brix comparable to Clery but better taste then Rumba and Clery +Glossy fruits and can be stored well

Allegro +Low susceptibility to Phytopthora cactorum and Verticillium and Mildew +Less susceptible to fruitrot (Botrytis) compared to Clery -Susceptible to Colletotrichum (Antracnose)

Allegro +Suited as fresh green plant and misted tip <should not be planted too deep <well drained soil <needs regular irigation after planting <Antracnose preventive spray

SONATA Selektion PRI-9802 Fresh Forward Cross Elsanta x Polka Midseason junebearer

Sonata -Very good pollen quality and easy fruit set No misshaped -2 -3 days later than Elsanta

Sonata -Short conical fruits -Very uniform medium size -Colour orange red and inside pink -Does not colour after storage -Sweet taste and more juicy than Elsanta -Very glossy berries also during storage

SONATA Produktion -Good yields outside in soil -Because of easy fruit set good variety to grow under rowcover and perforated plastic sheet -Fast to pick, berries click off easily, not grading

SONATA -Winterhardy compared to Elsanta -Good adapted in northern areas with high chilling -Good yields with Frigoplants -Less susceptible to raindamage compared to Elsanta

Elsanta Sonata

SONATA Diseases -less susceptible to mildew (Sphaerotheca mac. ) and angular leaf spot (Xanthomonas) -susceptible for red core root rot (Phytophthora cactorum and Rhizoctonia -attracts aphids especially under plastic

SONATA Nutrition -Higher need of manganese Mn and iron Fe -Optimum p. H is necesssary <NH 4 NO 3 -Fe/Mn = 3/2 -Mn. SO 4 and Fechelate in dripirrigation or with foliar application (1 -2 kg/ha) -Needs a higher dosis of Magnesium <Kieseriet in preplant (100 kg/ha) <Fertilisation of MSO 4 Bittersalz with drip irrigation or foliar treatment(50 kg/ha)

SONATA Outdoor production -More frost resistant than Elsanta -Frigoplants in double row system 4045. 000/ha -Cover with sheet lutrasil for winterprotection -Good yield in late June-early July

SONATA -Sonata flowers covered by the leafs which protects them from late night frost -In „Freiland“ strong vegetative multicrowned plants which can be very productive -Strawberries can be covered partially by leaves and first trusses are usually short<<a preventive treatment against Botrytis and Rhizoctonia are necessary

SONATA Magnesium -Needs a higher dosis of Magnsium <Kieseriet in preplant (100 kg/ha) <Fertilisation of MSO 4 Bittersalz with drip irrigation or foliar treatment(50 kg/ha)

SONATA Manganese and Iron -Higher need of manganese Mn and iron Fe -Optimum p. H is necesssary <NH 4 NO 3 -Fe/Mn = 3/2 -Mn. SO 4 and Fechelate in dripirrigation or with foliar application (1 -2 kg/ha)

SONATA Outdoor production -More frost resistant than Elsanta -Frigoplants in double row system 4045. 000/ha -Cover with sheet lutrasil for winterprotection -Good yield in late June-early July
