 note = {1) A firm-fruit cucumber line was selected by the fruit firmness from the progeny of crosses between 'Shinsyo Shirokawa', a Chinese cultivar with high fruit firmness, and three Japanese cultivars of 'Sharp 1' (greenhouse type), 'Natu-fushinari' (North-Chinese type with good-taste) and 'Encore 10' (greenhouse type with relatively good-taste). It was registered as 'Kyuuri Chuukanbohon Nou 4' (Cucumber Parental Line 4) in October 2006. 2) The fruit length is around 23 cm, the shape is cylindrical and the skin color is pale green. Compared with a Japanese representative cultivar of 'Hisaki', sweetness is somewhat lower. Weak astringency may also be detectable. It has approximately 10% firmer fruit than 'Hisaki'. The firm fruit trait is believed to be controlled by several nuclear genes -with incomplete dominance. Its texture is better than those of common cultivars, since it has firmer and thicker flesh. 3) It has a relatively larger plant size, such as the size of leaves and the length of the internodes is longer than those of common Japanese cultivars. Although the harvest start is delayed since the fruits set only on lateral branches, the fruit-yield is almost equal to 'Hisaki'. This parental line is promising for breeding commercial cultivars with firm fruit. This can be cultivated from early spring to late autumn all over Japan.},
