Effect of Soil Flooding Stress on Morphology and Yield of Five Lentil (Lens Culinaris Medic.) Genotypes

Abstract: Flooding is a serious environmental problem influencing lentil production in many areas of the world. The search for lentil germplasm tolerant to soil flooding is underway. This study compares the flooding induced changes in morphological traits and yield of five lentil genotypes. Three-week old seedlings of lentil genotypes BD3859, BD3905, BD3867, ILL5087 and BINAmasur1 were subjected to flooding for five days and the flooding responses on plant height, number of leaves, branching and yield were compared with that of non-flooded control plants. Flooding reduced plant height relative to control plants that ranged between 6 and 35% at the end of flooding. Flooding also promoted extensive leaf shedding, resulting in severe reduction of leaves per plant throughout the experiment. The production of secondary branches rather than primary ones during post-flooding phase was highly evident in this study. The genotypes differed greatly in producing a number of secondary branches. The genotype BINAmasur1 produced 85% while ILL5087 produced only 29% secondary branches in comparison to non-flooded plants. BINAmasur1 in flooded condition showed the lowest reduction of seed yield (50%) followed by BD3859, while severely affected ILL5087 reduced seed yield to 90%, when compared to control. The higher yield of BINAmasur1 in flooding was attributed to rapid production of secondary branches, higher number of pods, bolder grain size and better harvest index than the other lentil genotypes.
