'Tomato Cyuukanbohon Nou11', a tomato [Lycopersicon esculentum] parental line with a short-internode trait

'Tomato Anou 10' with a short-internode trait was developed at the National Institute of Vegetable and Tea Science, and was registered as 'Tomato Chuukanbohon Nou 11' in 2006. 'Tomato Chuukanbohon Nou 11' was selected from the cross between 'Momotaro 8', the commercial Fsub(1) hybrid released by Takii and Co., Ltd. that has been widely cultivated in Japan, and a Fsub(4) plant derived from the cross between 'Morioka 7' and 'Momotaro 8'. 'Morioka 7' is the processing tomato line with a short-internode trait, developed at the Morioka Branch of the Horticultural Research Station. The length between the sixth fruit truss and the cotyledon of 'Tomato Chuukanbohon Nou 11' is about 70% of that of 'Momotaro 8'. The 'Tomato Chunkanbohon Nou 11' reduces the time of demoting the stem of a plant when the plant is trained to a single stem and supported by strings. The Fsub(1) between 'Tomato Chuukanbohon Nou 11' and 'Tomato Chuukanbohon Nou 9' with a normal internode trait produced a mid-parent value. From the segregation of individuals with a short-internode trait equivalent to that of 'Tomato Chuukanbohon Nou 11' in the Fsub(2) generation, it seemed that the short-internode trait was controlled by a few genes with major effect. In addition, the short-internode trait is not associated with the fruit size, hardness or soluble solid contents. The fruit of 'Tomato Chuukanbohon Nou 11' is slightly flattened round, pink in outer color and the weight is 170 g on average. 'Tomato Chuukanbohon Nou 11' is not yet suitable for the commercial market, because its fruit has a low content of soluble solids and is prone to be malformed compared with 'Momotaro 8'. However, it is a highly promising as breeding material for the fresh-market indeterminate variety with a short-internode trait. 'Tomato Chuukanbohon Nou 11' is resistant to fusarium wilt race-1 and susceptible to bacterial wilt, verticillium wilt and ToMV.
