1. 'Sanukinomezame' is a hybrid asparagus cultivar bred by the single cross of a female plant, 'No. 17', and a male plant, 'No. 16', which had been selected at the Kagawa Prefecture Agricultural Experiment Station. It sprouts extremely early, its spears open late, and the yield is high. A varietal registration was applied for under the Seeds and Seedlings Law in July 2002. 2. According to the "Standard Description of Characteristics for the Identification of New Varieties 1983 : Asparagus" , the plant height and the height from the base to the first branch are somewhat higher. Spears are greenish ; anthocyanin expression is slightly higher in the stems ; and it has a large number of stems. The head of the spears is green and tight, and it opens late. It has a low chilling requirement, sprouts extremely early, has high winter survival, and elongates at low temperature. 3. 'Sanukinomezame' sprouts earlier in spring than 'Welcome' and 'Mary Washington 5 OOW' by one week in greenhouse cultivation and by two months in open field cultivation. It is possible to harvest it from late December, when the supply is scarce and the price is high, and the external appearance is good throt period. Therefore, an increased yield of spring sprouts and an improved yield of good-quality summer sprouts can be expected.
