There are two types of peppers at JA Esashi, and the ‘Sarara’ variety seems to be the most popular. Developed by the Institute of Horticultural Plant Breeding, a public interest incorporated foundation located in Kamishiki, Matsudo City, Chiba Prefecture. The fruit has a high fruiting rate and few wrinkles. The fruit color is dark green and contains more chlorophyll and ascorbic acid (vitamin C) than common green varieties. It has very good fruit setting, and it seems that a stable harvest is possible from the early stage. In addition, green peppers have little grassy smell and little bitterness, so it seems to be suitable for raw eating such as salads. Pepper micro-mottle virus (PMMoV (P1.2): A 300-nm rod-shaped virus that infects peppers and tobacco. It causes obscure mosaic spots and chlorosis on leaves and fruits, PMMoV). Infection spreads by seed, soil, and contact transmission.When green peppers are infected with this disease, mosaic symptoms appear on the leaves, and then growth is suppressed.The virus is highly contagious, and it is also underground. There is a high risk for new cultivation in fields where the disease has occurred in the past because the virus remains in the roots left behind for a long time. It is recognized that plants infected with certain viruses are not infected with the same or closely related viruses. Therefore, it seems that inoculation of plants with pre-attenuated viruses can prevent infection with virulent viruses. Developed a “plant vaccine” by identifying the gene that attenuates PMMoV. This plant vaccine showed a high control effect in test cultivation, and it seems that it is registered as a biopesticide and used. In addition, if a high positive rate is estimated from the method of estimating the norovirus positive rate using the amount of RNA as an index, it may be possible to reduce time and costs by omitting norovirus detection.) has been confirmed to have resistance (L3). Cropping types from semi-forcing to summer / autumn seem to be the most suitable.
In 2015, the 4 JAs in the southern part of the prefecture achieved 1 billion yen in sales of green peppers, and it seems that they have been working on expanding production with the next target of 1.3 billion yen in Japanese yen. After that, with the cooperation of producers and related organizations, the sales amount in FY2021 reached 1.4 billion yen, achieving the target. Amid the rapid changes in the production environment and distribution trends, there is a need for a stable supply as a main production area for summer and autumn peppers. JA Iwate Furusato, JA Esashi, JA Ofunato, JA Iwate Hiraizumi, and JA Zennoh Iwate are hosting the commemorative tournament. In addition, JA Zennoh Iwate Gardening Department South of the Prefecture Gardening Center Director has set a goal for the future, aiming to achieve 1.7 billion yen in 2024, and will work together as a brand production area for summer and autumn peppers. They vowed to unite again.
Iwate Prefecture is the second largest producer of summer and autumn peppers in Japan after Ibaraki Prefecture. I also plan to learn the cultivar characteristics of the TSWV (tomato spotted wilt virus) resistant green pepper “TSR Sarara”.
