京核1号是由北京市农科院作物所以杂交结合系谱法选育而成。1993年2月通过了北京市品种审定委员会审定和命名。特征特性该品种长芒、白壳、白粒,穗呈纺锤形,穗层齐,落黄好。幼苗半匍匐,叶片健壮,叶色较深。株高90厘米上下,茎秆有韧性,抗倒伏能力较强。籽粒大、硬
Beijing nuclear on the 1st by the Beijing Academy of Agricultural Sciences crop hybridization genealogy method bred. February 1993 passed the Beijing Variety Approval Committee and named. Characteristics of the species Changmang, white shell, white grain, spike was spindle-shaped, spike layer, falling yellow good. Seedlings semi-prostrate, robust leaves, leaf color darker. Height of 90 cm plant up and down, stalk toughness, anti-lodging ability. Large grain, hard
