The Relationship

The variation of protein content and correlations between protein content and agronomic traits were studied on materials in variety trials over five years and at two locations in southern Finland. Protein content and protein yield of a given genotype varied widely in different years. High temperature during the growing season was the main climate factor influencing protein content. Statistically significant variation in protein content was found between different genotypes. Correlations between protein content and seed yield were weak, negatively significant in only two years. The relationship between seed weight and protein content was negative in all years. Late maturity was positively associated with protein content in all years and at both locations. It is suggested that breeding for protein productivity in northern conditions it is more effective to improve seed yield and yield stability than to attempt improving protein content.

Field pea is used for human consumption or as livestock feed. The yield of pea seeds can be significantly decreased due to the genetically determined tendency of peas to pod shattering. This study aimed to evaluate the effect of pod sealant application on the quantitative and qualitative traits of the seed yield of two pea cultivars: Arwena and Tarchalska grown in south-western Poland in the years 2018–2019. Pod sealant application showed higher values of analysed quantitative and qualitative traits: number of pods per plant, number of seeds per plant, seed weight per pod, 1000-seed weight, seed yield, dry matter of seeds, protein content in seeds, and total protein productivity, except the number of seeds per pod. For both years (2018–2019), the interaction of cultivar and pod sealant application showed a significant effect on the number of seeds per plant, total protein content, total protein productivity, and seed weight per pod in 2019. Therefore, the pod sealant application can be a relatively simple way to improve the yielding of field peas.

Abstract The present investigation was carried out to evaluate agronomic performance and oil quality of seven sunflower genotypes at Shandaweel Research Station, Agricultural Research Center, Sohag, Egypt during 2018 and 2019 summer seasons. These genetic materials were sown in a randomized complete block design having three replications. Significant genetic variations among evaluated sunflower genotypes for agronomic traits and oil quality were observed. The superior sunflower genotypes were Line 120 for seed yield per hectare (3102.38 kg), Sakha 53 for seed oil content (44.63 %) and Line 125 for oil quality where it contained the highest proportion of unsaturated fatty acids (89.20 %). The phenotypic coefficients of variation were slightly higher than genotypic coefficients of variation for all studied traits. High heritability (exceeded 60%) and genetic advance as percent of mean (ranged from medium to high, exceeded 10%) was observed for most studied traits. Seed yield per plant positively correlated with plant height, stem diameter, head diameter, and 100-seed weight and most chemical traits at phenotypic and genotypic levels. Maximum phenotypic direct effects on seed yield per plant were observed for 100-seed weight, head diameter and total unsaturated fatty acids. While, the highest genotypic direct effect on seed yield per plant was observed for head diameter. Hence, most studied traits could be employed as selection criteria for improving evaluated sunflower genotypes.

Moisture Conditions

When averaged over a wide range in soil nitrogen and moisture conditions, cultivar differences in yield and protein content of non-inoculated field peas (Pisum sativum L.) were relatively small. The inherent differences in seed weight were responsible for most of the variations in yield among the three cultivars. Nitrogen fertilization in the growth room experiment markedly increased plant weight, seed yield and protein content, and water-use efficiency was substantially improved. When maintained within the upper half of the available range, soil moisture supply had only a limited influence on plant growth. Periodic wilting did cause a severe reduction in plant weight and seed yield, but there was little change in protein content. For these fertilizer and moisture treatments, responses in seed yield were primarily due to changes in number of pods per plant; the seeds per pod and seed weight were relatively stable. It appeared that field peas were efficient converters of soil nitrogen to seed protein and, in the absence of nitrogen-fixing bacteria, nitrogen fertilization was the principal factor influencing the protein content of field peas. The correlation coefficient between yield and protein content was very low.

A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.

The objective of this research was to quantify heterosis of agronomic traits and evaluate direct and indirect correlations among seed yield and other traits. A diallel involving six parents was grown in two localities. Seed yield (PG), one-hundred seed weight (PCS), number of pods per plant (NV), weight of aerial part of the plant (PPA), harvest index (IC) and number of seeds per pod (NGV) were evaluated. Positive values of heterosis were detected for all traits. Estimates of heterosis components were significative for most traits, showing effects of aditivity and dominance. The specific heterosis was more important than the variety heterosis, mainly in the locality Anhembi. MTBR-95-123800 presented the best potential per se and as parent in crosses, but it was excelled by some of the hybrids in the two localities. Number of pods per plant demonstrated to be suitable for indirect selection for PG.

Simazine [2-chloro-4,6-bis(ethylamino)-s-triazine] was applied at rates of 0.002–0.800 kg a.i./ha to field peas (Pisum sativum L.) as soil and as foliar applications for 4 yr. Band applications to the soil surface over the seeded rows and incorporated beside the seeded rows in a clay soil had no effect on seed yield or protein content. However, seed yield was increased 25% in the year that seeding was early (3 May) in a fine sandy clay loam, and seed placed into the center of a band into which simazine at 0.4 kg a.i./ha had been rototilled to a depth of 10–12 cm. There were no differences in weight per seed or protein content. Foliar applications were not effective.

Small fababeans (Vicia faba L.) were tested at one location for 2 yr at six seed rates (60–260 kg/ha) and two row spacings (15 and 30 cm). Results indicate that narrow spacing outyields wide spacing at all seed rates, the average advantage being 18.9 q/ha and 5.0 q/ha for 1971 and 1972, respectively. Seed yield increased with seed rate; highest yields were obtained at a seed rate of 260 kg/ha and 15 cm spacing. Treatments had no significant effects on 1,000-seed weight hectoliter weight, or protein content. Yield component analysis revealed that the number of pods per plant decreased with increased seed rates, but weight per pod was not affected. It is concluded that seed yield is a direct function of the number of mature pods per unit area.

AbstractIn breeding process it is important to know the extent of association between the traits that affect the yield. Objective of this study was to determine genotypic and phenotypic correlation and path coefficients in 50 sunflower hybrid combinations in order to identify research priorities in sunflower breeding. Relationships between seed yield and five bio-morphological traits in sunflower (oil content, protein content, 1,000-seed weight, head diameter and plant height) were studied. Head diameter had the highest correlation coefficient with seed yield, at phenotypic and genotypic level. Path analysis revealed that all evaluated traits had positive influence on seed yield at both, genotypic and phenotypic, levels. The highest direct effect on seed yield was found for head diameter, while protein content had the lowest direct effect on seed yield. Study has shown that the greatest improvement in sunflower seed yield can be achieved through selection on head diameter.

Late maturity often causes substantial losses in yield and quality of chickpea (Cicer arietinum L.) in the short growing season in western Canada. This study determined optimum harvest management practices to minimize losses due to late maturity. Kabuli chickpea was grown in southwestern Saskatchewan from 2002 to 2004, and seed and straw were harvested with various harvest management practices. Seed yield in 2004 was higher compared with 2002 and 2003, but the 2004 seed samples had a high percentage of shrivelled and green seeds. Seed yield, weight per seed and harvest index (HI) were highest when the crop was directly combined at natural maturity either before or after a killing (-5°C) frost. On average, swathing at early or late maturity stages decreased seed yield, weight per seed and HI significantly compared with direct combine practices. Seeds from the swathing treatments had high percentages of green and shrivelled seeds with high levels of fungal colonization. Both seed and straw from swathing had the poorest feeding quality measured as neutral detergent fibre, acid detergent fibre, and organic matter content and digestibility. Desiccation of chickpea plants with Reglone or low dosages of glyphosate when 80% of pods had turned colour did not advance plant maturity, nor did they affect seed yield or HI compared with direct combine practices. It is concluded that in the short growing season in western Canada, harvest of chickpea at natural maturity either prior to or after a killing frost may optimize the seed yield and quality. Regardless of harvest practices, the quality of both seed and straw in chickpea may be suitable as salvage feed materials for beef livestock. Key words: Cicer arietinum, desiccation, direct-combine, maturity, glyphosate stress, swath, salvage feed
