Evaluation of mungbean cultivars for resistance to iron deficiency

Country
Thailand

Description

[Synopsis]

Ten mungbean cultivars were evaluated for their resistance to iron deficiency based on the developed of chlorosis symptoms, plant growth and seed yield under field conditions on a calcareous soil in Thailand. KPS2 cultivar was highly susceptible ; KPS1, PSU1 and Pag-asa1 cultivars were somewhat susceptible ; VC1163B cultivar was moderately tolerant ; CN36, CN60, UT1 and CNM-I cultivars were tolerant and ; CNM8509B cultivar was highly tolerant to iron deficiency. Compared with the susceptible cultivar KPS2, the tolerant cultivar UT1 had a greater ability to lower the pH of the nutrient solution in response to iron deficiency. Acidification of the medium in response to iron deficiency may contribute to the efficient solubilization of iron from calcareous soils, and it is closely related to the tolerance of iron deficiency in mungbean cultivars.
