Yield Performance of Faba Bean Cultivars under Different Environmental Conditions in Greece

Abstract

Faba bean is an important grain legume, grown for human consumption and animal feed and can be used as an alternative to soybean protein. Drought and heat strongly influence faba bean growth and production, especially in flowering and pod development stages. The aim of this study was to determine the response of six cultivars to different environmental conditions during the 2018-2019 growing season. Four inbred lines and two commercial cultivars were sown in different environments in South, Central and North Greece. At each location, a randomized complete block design with four replications was used. Different characteristics such as plant height, number of pods plant-1, number of seeds pod-1, seed yield and 1000-seed weight, were recorded. The results indicated that all traits were significantly affected by different climatic conditions and cultivars. In most cases, seed yield and 1000-seed weight decreased with increasing drought conditions in the southern site. KK10 produced higher yield and pods plant-1, especially in North and Central Greece. The late maturity cultivars, ‘Polycarpe’ and KK14, showed lower values for the seed traits under all locations. Multi-location trials are useful for the evaluation of new cultivars and lead to an increase in production of feedstuff directly available to farmers.

Tolerance of faba bean plants to drought stress and plant density via yield components and pathogenicity tests

“…It appears to be generally true that there are no appreciable variations between three irrigations of slightly different magnitudes that are applied and regular irrigation (control). Similar results were also obtained by [17][18][19][20][21][22].…”

Effect of plant density and drought stress on seed productivity and biochemical composition of faba bean plants

“…These results are in the line with those accomplished by . [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] Data in table (2) exert that faba bean densities evidentiate there were significantly differences in seeds weight kg plot-1 in both seasons. The results indicates that density 20 kg/fed was the highest seeds weight ( 0.143 kg plot-1), followed by density 30 kg/fed ( 0.131 kg plot-1) then density 40 kg/fed (0.123 kg plot-1) in the first and in the second seasons density 30 kg/fed was the highest seeds weight ( 1.035 kg plot-1), followed by density 20 kg/fed ( 1.029 kg plot-1) then density 40 kg/fed (1.018 kg plot-1), respectively .…”

Variability in drought stress response in a panel of 100 faba bean genotypes

“…A positive correlation between maturity and yield was found in the control condition, but not in the stress treatment. Katsoulieri et al. (2020) described that later ripening genotypes showed greater susceptibility to drought stress during early pod set compared to genotypes with early maturity.…”

“…A positive correlation between maturity and yield was found in the control condition, but not in the stress treatment. Katsoulieri et al (2020) described that later ripening genotypes showed greater susceptibility to drought stress during early pod set compared to genotypes with early maturity. This was supported by Khan et al (2010) as well as Manning et al (2020), where early flowering is considered an important adaptation trait for cool-season legumes growing under semi-arid conditions.…”
