Abstract

Soybean genotypes G00006, BD2336, AGS383, PK472, BCS1, NCS1, BU Soybean1 and BARI Soybean6 were evaluated under 20% (drought) and 80% (control) of field capacity based on morpho-physiological and yield response to drought. The results revealed that plant height, leaf number, chlorophyll content, photosynthesis, stomatal conductance, transpiration rate, relative water content and water uptake capacity of soybean drastically reduced due to drought. However, root: shoot ratio increased under drought condition. Across the genotypes, the root : shoot ratio ranged from 0.20 to 0.47 in control, while 0.22 to 59 in drought condition. Genotypes BD2336, AGS383 and G00006 produced higher number of pods and seeds, whereas minimum yield reduction was recorded in AGS383 under drought. Based on drought tolerance index, AGS383 ranked 1st, while BD2336 and PK472 ranked 2nd and 3rd position, respectively. High grain yielding ability of AGS383 suggested that it could be cultivated in drought prone environment. J. Bangladesh Acad. Sci. 47(2); 223-240: December 2023

基于形态和生理特性剖析大豆基因型的干旱胁迫耐受性

根据形态生理和产量对干旱的反应，对大豆基因型 G00006、BD2336、AGS383、PK472、BCS1、NCS1、BU Soybean1 和 BARI Soybean6 在 20%（干旱）和 80%（对照）田间能力下进行了评估。结果表明，干旱导致大豆的株高、叶片数、叶绿素含量、光合作用、气孔导度、蒸腾速率、相对含水量和水分吸收能力急剧下降。然而，根：芽比在干旱条件下有所增加。不同基因型的根芽比在对照条件下为 0.20 至 0.47，而在干旱条件下为 0.22 至 59。基因型 BD2336、AGS383 和 G00006 结荚数和种子数较高，而 AGS383 在干旱条件下减产最少。根据抗旱指数，AGS383 排名第一，BD2336 和 PK472 分别排名第二和第三。AGS383 的高产能力表明它可以在干旱环境中种植。47(2); 223-240：2023 年 12 月
