A new rice variety 'Yumepirika'

A new variety of non-glutinous paddy rice, 'Yumepirika' was developed by Hokkaido Kamikawa Agricultural Experiment Station (Rice Breeding Laboratory Designated by the Ministry of Agriculture, Forestry and Fisheries Japan) in 1997. It was derived from the progeny of the cross between 'Satsukei 96118' and 'Jouiku 427'. It was registered as a recommended variety of Hokkaido in 2008. The main characteristics of 'Yumepirika' are summarized as follows: 'Yumepirika' is a moderate maturing cultivar, and its heading dates are similar that of 'Hoshinoyume' and 'Oborozuki', its maturing dates are slightly later than that of 'Hoshinoyume' and 'Oborozuki'. Tolerance to cool weather during the booting stage is moderate strong to strong, but is inferior to that of 'Hoshinoyume' and 'Oborozuki'. Field blast resistance is weak, but is superior to that of 'Hoshinoyume', and inferior to that of 'Oborozuki'. The genotype of blast resistance is Pii and Pik. Yield potential is superior to that of 'Hoshinoyume' and 'Oborozuki'. Grain transparency is higher than that of 'Oborozuki', and is similar that of 'Hoshinoyume'. Grain quality is similar to that of 'Oborozuki', but inferior to that of 'Hoshinoyume'. The amylose content in the endosperm of 'Yumepirika' is moderately low. The protein content in the endosperm is similar that of 'Hoshinoyume', and is lower than that of 'Oborozuki' The eating quality of cooked rice of 'Yumepirika' is clearly higher than that of 'Hoshinoyume', and is similar or slightly higher than that of 'Oborozuki'. Because of superior characteristics mentioned above, 'Yumepirika' is expected to replace a part of 'Hoshinoyume' and all of 'Oborozuki'. Then it would contribute to the stable production of good eating quality rice and improvement eating quality of rice in Hokkaido.
