Background: Faba beans (Vicia faba L.) are important grain legumes but, as with many crops, these are also susceptible to water deficit. The aim of this study was to evaluate the yield components of twenty faba bean genotypes grown under water deficit.Methods: Three water treatments were applied, 25%, 50% and 100% of field capacity. A split-plot arrangement in a randomized complete block design with three replicates was used.Result: The faba genotypes Gazira2, Kamline, L4, Cairo7 and Giza402 reached flowering earlier than other genotypes through stress-escape mechanisms. Genotypes L4, Gazira1, Kamline, X.735 and Gazira2 had the highest seed yield under water-deficit conditions. Genotypes L4, X.735, 989/309/95, Kamline and Gazira1 exhibited the highest levels of biological yield. Finally, the genotypes Kamline and L.4 had higher yields and yield components under water-deficit stress. Consequently, they should be considered for use in breeding programs aimed at developing new cultivars that are better adapted to harsh environmental conditions.

A near-isogenic faba bean (Vicia faba L.) line, segregating in a 1:1 ratio of male-fertile to male-sterile plants, was used to study the importance of insect pollinators on ovule fertilization and yield components of the first five flowering nodes. The fertilization of ovules from open-pollinated plants at the higher insect pollinator site of Dijon, France was 83%, as compared with 50% at the lower insect pollinator activity site of Saskatoon, Canada. No significant differences in total fertilized ovules were found between male-fertile and male-sterile plants at Dijon, but male-fertile plants at Saskatoon had significantly more fertilized ovules than male-sterile plants. Seed production on the first five flowering nodes was significantly greater at Saskatoon. Thus, while insect pollinators are important in determining the potential yield of a faba bean plant, other factors, such as environment, determine the ultimate yield.Key words: Vicia faba, ovule fertilization, seed yield, faba bean, male sterility

Crop Weed Competition

Field experiments were conducted during the two growing seasons of 1999 and 2000 at the research farm of the Jordan University of Science and Technology (JUST) to study the effect of the time of weed removal on the yield and yield components of faba bean (Vicia faba L.). Removing weeds from 25 to 75 days after crop sowing led to significantly larger yields than on plots which were not weeded. Maximum yield was obtained in both years when weeds were removed thrice at 25, 50 and 75 days after crop sowing.

Hayman's diallel cross analysis was employed to investigate the nature of the genetic control and heritability of yield, yield components, and phenological and agronomic characters in F1 and F2 generations of spring faba beans (Vicia faba L.). High-yielding S4 inbred lines from five open-pollinated faba bean cultivars were used as parents to generate complete F1 and F2 diallels. The S5 inbred line parents and the 20 cross combinations were planted in randomized complete block experiments with six replications. All characters in the F1 diallel and in the F2 diallel with the exception of days from planting to maturity met all of the assumptions required for Hayman's diallel analysis. Yield, total dry matter, harvest index, and pods per plant exhibited significant apparent overdominance in both the F1 and F2 diallels. It is concluded that substantial immediate increases in yield and total dry matter could be expected from exploiting the apparent overdominant gene action found for these characters in these crosses via F1 hybrids or synthetics. Key words: total dry matter, harvest index, diallel crosses, inheritance, Vicia faba L.

Development of high yielding and stable cultivars of various legume crops across different environments is very important for their adoption by farmers. In addition, climate change sets new challenges to major crop species and especially to grain legumes such as faba bean (Vicia faba L.) for adaptation to stressful environments. The present study focused on evaluating faba bean genotypes developed for yield and stability across different environments. The study was conducted in three areas of Greece (South, Central, and North) for two consecutive growing seasons (2018–2019 and 2019–2020). Biomass yield, seed yield, and yield components were studied together with plant height, earliness, and water use efficiency. Genotype, environment, and their interaction affected most of the studied characteristics. The environment was the major source of variation for most of the characteristics, as it explained 81–93% of total variation, and only in the thousand seed weight the variation was 49% for the environment and 40% for the genotype. Genotype had a much smaller effect on the remaining characteristics (1.2–3.9%), and the interaction between environment x genotype accounted for up to 0.5–17% of the variation. GGE-biplot analysis for high yield and stability across different environments revealed three genotypic types: genotypes well adapted either for biomass or seed yield and genotypes with high adaptation capacity for both traits under typical Mediterranean conditions. These results indicated that screening faba bean genotypes under different environmental field conditions is essential to identify adaptable cultivars to be cultivated for biomass and/or seed yield or to be used in breeding programs.

In order to investigate the effects of planting date and plant density on the yield and yield components of bean (Vicia faba L.) cultivars, the experiment was conducted at Safi Abad Agricultural and Natural Resources Research Center in 2017 and 2018. The experiment was performed as the split factorial in the randomized complete block design with three planting dates (Oct. 12, Nov. 1, Nov. 21) as the main plot and three density levels (10, 15 and 20 plants/m2) and two genotypes (Saraziri and line 62) as the subplots with three replications. The considered traits were the number of pods per plant, number of seeds per pod, 1000-seed weight, grain yield, biological yield and harvest index. The results of this study showed that the planting date, density and genotype, as well as their interactions had a significant effect at 1% and 5% probability level on the yield and yield components of bean.
