【摘要】 Grls（Guizhou recessive long-culm）是作者1983年在杂交后代中发现的一个水稻高秆隐性新类型。本文报道了Grls及其测交F₁株高的特点。引用了国外报道的两个水稻高秆隐性品种（日本的LM₁和美国的76:4512）的资料进行比较,三者各具有不同的秆型结构。Grlc为正常伸长型。LM₁为中下部节间伸长型,76:4512为第一间伸长型。Grlc具有类似矮秆水稻的良好秆型结构及其它一些优点。它的发现,可能对进一步提高杂交水稻的制种产量和克服籼粳杂交F₁的倒伏问题带来希望。更多还原

【Abstract】 Grlc (Guiitou fecessive long-culm) is a new recessive tall [type in rice(oryza sativa L.)aiscovered by the authors in a filial generation in 1983. This paper reported the characteristics of the plant height character of Grlc and its testcross F1. It has a special culm structure as compared with LM1 of Japan and 76 : 4512 of America (Both are recessive tall rice lines). Grlc is a normal-elongation type.LM1 belongs to an elongation type of the middle and lower internode ard 76 : 4512 is classified as an elongation of uppermost internode. Grlc has a good culm structure and some other fine characters sinilar to dwarf rice varieties. The discovery of Grlc might bring much hope of further increasing the output of hybrid seed and preventing F1 generation lodging in the hybrid of Indica and japonica更多还原
