Screening for drought tolerance in mungbean

Abstract

Field experiments were conducted to screen the mungbean genotypes based on root characters and root penetration ability. Observations on root and shoot characters viz., root length, shoot length, number of roots, root diameter, fresh weight of root, fresh weight of shoot, dry weight of root, dry weight of shoot, root volume, growth and yield parameters viz., plant height, number of branches, number of pods per plant, number of seeds per pod, 100 seed weight, seed yield per plant were recorded. Based on the root characters, the genotypes HUM 1, VMGG 67, VMGG 82, VMGG 83 and VMGG 90 were found to be promising. They also performed well in the field experiments. These genotypes were crossed with high yielding varieties like VBN 1, VBN 2, VBN 3 and KM 2 to get F 1. Among the 20 crosses obtained, three crosses VMGG-83/VBN 2, VMGG-90/VBN 3 and VMGG-83/VBN 1 were found to perform well in F 2 and they will be forwarded to next generation.

Discrimination of Mung Bean (<i>Vigna Radiata</i> L.) Genotypes Exposed to PEG-Induced Water Deficit Reveals the Selection Criteria for Improved Breeding from Germination to Seedling Development

“…In brief, drought stress impedes crop growth and development, resulting in significant yield reduction [51][52][53]. Seedling establishment under drought stress conditions is a critical factor for a better yield [6].…”

Plant tolerance to drought stress: Complexity and mechanism across physiological, molecular and biochemical scales

“…Decline in blooming rate, seed setting, fertilization, and plant productivity are carried out by exposure under drying conditions during the generative phase of development stage (Mahla et al, 2017;Akram et al, 2018). A wide range of crops, including sorghum (Sanjari et al, 2021;Sarshad et al, 2021), maize (Goodarzian Ghahfarokhi et al, 2015Hammad et al, 2017), wheat (Mahla et al, 2017;Jin et al, 2018;Kulczycki et al, 2022), rice (Akram et al, 2018;Yang et al, 2019), mung bean (Prakash et al, 2017;Bangar et al, 2019;Jincy et al, 2021), soybean (Dong et al, 2019;Felisberto et al, 2022), andlentil (El Haddad et al, 2022), have been studied for their responses to drought stress. The plant growth cycle is crucial for controlling its response to stress, and it depends on drought duration and its intensity (Çakir, 2004).…”

Responses of Mungbean to Water Deficit, Water use Efficiency and Drought Resistance

“…Water and salt stress are the main environmental factors which act as major constraints for Mungbean. Stress changes the growth pattern by affecting the maj or physiological and biochemical parameters (Prakash et al 2017).…”
