Yam bean (Pachyrhizus erosus (L.) Urban) is an underutilised tuberous legume crop which has great potential as a food crop. As a root crop, it produces high yields and as a legume, it can produce protein‐rich food. The phenological growth stages of yam bean are first described here using BBCH (Biologische Bundesanstalt, Bundessortenamnt and Chemische Industrie) scale. We have developed a basic and extended numerical BBCH scale for the identification of different phenological growth stages of yam bean. All phenological stages, including germination (stage 0), leaf development (stage 1), formation of side shoots (stage 2), stem elongation (stage 3), tuber formation (stage 4), inflorescence emergence (stage 5), flowering (stage 6), development of pods (stage 7), ripening of pods (stage 8) and senescence (stage 9) are described using the BBCH scale. This BBCH phenological study in yam bean will be helpful for better crop management, crop improvement and characterisation of germplasm. This scale will also be useful for the yield enhancement of this crop as an emerging underutilised tuber crop.

根据扩大的BBCH规模,未充分利用的山药豆(Pachyrhizus erosus L.Urban)的物候生长阶段

山药豆(Pachyrhizus erosus(L .)城市)是一种未充分利用的块茎豆类作物,具有作为粮食作物的巨大潜力。作为块根作物,它可以产生高产,而作为豆类作物,则可以生产富含蛋白质的食物。这里首先使用BBCH(Biologische Bundesanstalt,Bundessortenamnt和Chemische Industrie)量表来描述山药豆的物候生长阶段。我们已经开发了一个基本的和扩展的数字BBCH量表,用于识别山药豆的不同物候生长阶段。所有物候阶段,包括发芽(阶段0),叶片发育(阶段1),侧芽形成(阶段2),茎伸长(阶段3),块茎形成(阶段4),花序出苗(阶段5),开花(阶段)第6阶段),豆荚发育(第7阶段),豆荚成熟(第8阶段)和衰老(第9阶段)使用BBCH量表进行了描述。这项针对山药豆的BBCH物候研究将有助于更好的作物管理,作物改良和种质鉴定。这种规模对于新兴的未充分利用的块茎作物,也将有助于提高该作物的产量。
