摘要
桂蹄4号是以桂蹄2号为材料,通过茎尖组织培养产生的优良变异单株筛选培育而成的早中熟荸荠新品种。生育期130~140 d(天);植株生长势强,球茎横椭球形、脐部微平,皮褐白色,淀粉含量47.0 mg·g^-1,可溶性糖含量7.95%,口感脆甜、少渣,品质好;平均单球质量26.2 g,每667 m^2产量2200 kg左右,田间对秆枯病的抗性与对照桂蹄2号相当,适宜广西及其周边地区种植。
‘Guiti No.4’a new early-medium ripening water chestnut cultivar developed by taking‘Guiti No.2’as material,screened and bred from mutant single plant of stem-tip tissue culture.The whole growth period is 130-140 days.The plant has strong growth vigor.The corm is of transverse ellipsoid shape.The umbilical region is slightly flat.Its peel is brownish white in color.Its starch content is 47.0 mg·g-1,and soluble sugar content is 7.95%.It tastes crisp and sweet with less dregs and good quality.The average single corm weight is 26.2 g.It can yield about 33 t·hm-2.In the fields,its resistance to stem blight is equivalent to that of the contrast‘Guiti No.2’.It is suitable to be planted in Guangxi and surrounding areas.
