“…As reported, the 1000 seed weight was negatively correlated with the number of pods per plant, which, however, has not been recorded in the present research. The results of the analysis of regression (Table 8) show that the essential components which determine the faba bean yielding are, in the following order: seed weight per pod (70.5%), the number of seeds per pod (54.5%), the number of pods per plant (54.3%) and 1000 seed weight (48.9%), which coincides with the results of the research reported by Esho and Salih (2021) and by Singh et al (2021). According to Tivari and Singh (2019), the faba bean seed yield points to a significant value of the correlation with all the components, except for 1000 seeds.…”

“…The average number of seeds per pod in faba bean was 2.86, and the seed weight per pod-1.46 g, while the 1000 seed weight-507 g. The values did not depend significantly on any of the factors applied in the experiment. However, Esho and Salih (2021) reported a direct positive effect on faba bean yielding being the number of pods per plant and 1000 seed weight, and according to Singh et al (2021), also the weight of pods per plant. Yucel et al (2013) have found that all the above faba bean components determining the seed yield depend on the total rainfall, which coincides with the results of the present research, however only for June and a period of June-August.…”

The research covered Polish low-tannin Faba bean ‘Albus’, and its yielding depending on the row spacing and plant density under very different humidity conditions across the research years. The mean multi-year faba bean seed yield was 4.01 t ha-1 and it was most correlated with the total rainfall in August and in June-August. Due to a considerable variation in the total rainfall and air temperature, the faba bean seed yield ranged from 0.69-2.14 t ha-1 in dry years (2018-2019) with high air temperature, from 6.64 to 6.59 ha-1 in humid years (2016-2017) with a considerably higher total rainfall and lower air temperature in June-August. There was no significant effect of the row spacing and plant density on the faba bean yielding, except for a significantly lower seed yield in 2019 following the application of the lowest plant density. Out of all the yield structure components, only the number of pods per plant for 60-75 plants per m2 was significantly lower than for 45 plants. The other yield structure components did not differ significantly due to the factors studied either, except for the LAI, the value of which for a narrow row spacing was significantly higher. There was found a significant correlation between all the plant traits and with the faba bean yield.

Introduction: The experiment was conducted in Research Farm, Rani Lakshmi Bai Central Agricultural University, Jhansi, during Rabi season 2019-2020 using augmented block design in five blocks. The objective was to assess the genetic variability and character association analysis of eighty-two wheat genotypes. Methodology: Eighty-two genotypes including three checks (HI1544, DBW110, and GW322) observed its various quantitative traits for genetic variation, heritability, genetic advance, and character association. The observations were recorded on fifteen agro-morphological and physiological characters viz; days to 50 percent heading, days to maturity, canopy temperature (oC), chlorophyll content, flag leaf width (cm), flag leaf length (cm), tillers per meter, peduncle length (cm), plant height (cm), spike length (cm), awn length (cm), 1000-grain weight (g), grain yield per plant (g), biological yield per plant (g) and harvest index (%). Statistical analysis was carried out by R Programming and SAS version 9.2 statistical software. Results: The genotypes IC443619, IC6165734, and IC624496 were having earlier days to maturity than the best check DBW110. HD3086, K0307, PBW343, RAJ3, 765, and MACS6478 have been found promising for grain yield per plant. The highest Phenotypic coefficient of variation (PCV) and Genotypic coefficient of variation (GCV) were recorded for tillers per plant followed by awn length, peduncle length, flag leaf length, flag leaf width, plant height, and spike length. Heritability in broad sense wide ranged from 26.3 percent for canopy temperature to 95.63 percent for grain yield per plant. The grain yield per plant showed a positive and significant correlation with biological yield per plant, harvest index, and tillers per meter, whereas it showed a negative significant association with awn length. Conclusion: The relationship between grain yield per plant and biological yield per plant, harvest index, and tillers per metre was positive and significant, indicating that an increase in these component characteristics will also boost economic grain yield per plant.

“…Experimental findings of the present investigation revealed that, yield per plant and spike length exhibited high and positive correlation. "Spike length showed positive and significant correlation with grain yield" [9,10]. "The increase in spike length is directly associated with increase in yield per plant" [11,1].…”

To determine the association among yield related traits on grain yield of mutant wheat, an experiment was conducted at the Agricultural Research Farm of R. B. S. College, Bichpuri, Agra (Uttar Pradesh). The application of physical mutagens such as X-rays, gamma rays, and neutrons, as well as chemical mutagens, for inducing variation is well set up. Induced mutations have been applied to the Joint offer of FAO/IAEA Division of Nuclear Methods in Agriculture, more than 1800 cultivars acquired either as direct mutants or derived from their crosses have been released globally in 50 countries. The correlation of twelve characters in wheat induced mutants was investigated. The number of spikelets per spike and spike length both had a significant and positive correlation with yield per plant. Selection for traits that are positively correlated with yield per plant could lead to increased yield. This suggests that selecting for these traits may be more effective in maximising grain yield.
