摘要《中国植物志》第九卷第一分册及其它的相关文献均无关于竹亚科簕竹属吊罗坭竹花的描述或记录，本文作者采集制作了该竹子繁殖器官标本，并分别用中文和拉丁文对其进行了描述，其主要特征：花枝长70~170 cm；花序为总状花序或简单的圆锥花序；花序轴粗，节明显；小穗含4~5朵小花；小穗无柄；小穗轴节间无毛，呈棒状；颖2，膜质；外稃长或等于内稃；鳞被2；雄蕊6；子房卵形；柱头3，呈毛刷状；颖果未见。

The results showed that length from flag leaf pulvinus to spike base has the largest coefficient of variance of 42.1% and 37.2% in both DS and WW environments, respectively, while the spikelet per spike has the smallest CV of 6.4% and 5.7%. Under different water regimes, spike number per plant, effective spikelet per spike and peduncle length contribute a lot to the stable grain yield. Genetic diversity indices of DTI were from 1.95 to 2.07, with an average value of 2.02. Based on the DTI of agronomic traits, all accessions could be clustered into seven groups, the first and third groups are not sensitive to the water regimes, and the second group is more suitable for planting in dryland.

结果表明：在雨养和灌溉条件下，穗叶距的变异系数最高，分别为42.1%和37.2%，单穗总小穗数的变异系数最低，为6.4%和5.7%；不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；性状耐旱指数的多样性指数在1.95到2.07之间变化，平均值为2.02；根据性状耐旱指数将供试材料分为7个类群，其中第I、第III类群材料表现为对水分条件不敏感，而第II类群材料更适于在干旱条件下种植。

Lower glume of pedicelled spikelet awned; lower floret of sessile spikelet absent or reduced to a small lemma; anthers ca.

The QTL controlling spikelet fertility and pollen fertility were investigated based on the Balilla/NTH//Balilla backcross population by SSR marker. For spikelet fertility trait, two QTLs, qSPTF1 on chromosome 1 and qSPTF6 on chromosome 6, were detected, and their additive effect were 13. 501 and -16. 414, respectively. According to previous studies, qSPTF6 was deduced to be same as S〓.
