Disease, insects, and mites.No sensitivity to any disease and pest has been observed for BLUECSOL11. Plant hardiness zone: The plants of the BLUECSOL11 variety were tested under the arid conditions of the northern coast of Peru, where the maximum temperatures in the year are 32? C. and the minimum are 13? C. The BLUECSOL11 variety can produce fruit all year round and does not require temperatures below 7? C. for flower induction. The area where its behavior was observed and evaluated does not have extreme temperatures to be able to determine cold or heat resistance. Productivity: BLUECSOL11 has a super high yield potential. The harvest begins after 6 months of the planting or pruning of the plants on the field and lasts for 24 weeks. Plant productivity in the first season is about 4.0 to 4.5 kg per plant and in the second season is around 4.5 to 5.5 kg per plant. 80% of the harvest is concentrated in 12 weeks. Storage qualities: BLUECSOL11 has a shelf life of more than 49 days under modified atmosphere storage at 1? C. and 35 days under controlled atmosphere storage at 1? C.
