Thirty-five sunflower (Helianthus annuus L.) hybrids and seven parental lines were analyzed for hull and oil content. The hull content varied from 21.6 to 28.2% in the hybrids. The oil content varied from 59.8 to 64.6% in the kernel and from 42.5 to 50.3% in the whole seed. The variation of these characters was even greater in the parental lines. Hull content was negatively correlated with both kernel and whole seed oil content and with seed weight. Oil content of the kernel was positively correlated with oil content of the whole seed. Some variation in ease of dehulling was observed using a barley pearler.

This study investigated the influence of plant density on several agronomic traits of four sunflower (Helianthus annuus L.) cultivars grown at Indian Head and Saskatoon, Saskatchewan in the semiarid prairies. At populations of 40 000–85 000 plants∙ha−1, plant density had no significant effect on seed yield. The increase in percentage oil content with increase in plant density (44.3–45.6%) was small but significant. As plant density was increased, days to flower, height and test weight increased while days to maturity, head diameter and average seed weight decreased. Cultivars × density interactions were generally not significant. Environment (five location-years) had a significant effect on all variables, and environments × cultivar interactions were significant for most of these. Results of this experiment indicated that testing of sunflower lines at several locations in the growing area would be necessary for best assessment but one plant density, suitable to that area, could be used.Key words: Sunflower, plant density, seed, oil, seed size, Helianthus annuus L.

SUMMARY Field experiments have been conducted to study the effect of organic and inorganic sources of nutrients applied alone or in combination on the growth and yield of sunflower. Application of a recommended dose of fertilizer (62.5:75:62.5 kg NPK ha-1) coupled with 10 t ha-1 of farmyard manure has recorded highest seed and stalk yields of sunflower. Growth and yield parameters were also favorably influenced by the application of the recommended dose of fertilizer coupled with farmyard manure. Seed oil content was not influenced by the application of organic or inorganic sources of nutrients.

Kernel Content

Oil content of the sunflower achene is determined by its components, namely kernel content and kernel oil content. The object of this study was to determine the heterosis and relative contributions of the parents to the achene oil, kernel oil and kernel content of the hybrid. Multiple regression equations showed that the two parents contribute equally to the achene oil content of the hybrids. Heterosis was observed in the kernel oil content and kernel content as well as the achene oil content. A heterotic effect of 47 g kg−1 over the mid-parent value was observed for achene oil content. For the achene oil components, heterotic effect of 44 g kg−1 was obtained for kernel oil content and 24 g kg−1 higher for kernel content. Key words: Sunflower, achene oil content, kernel oil content, kernel content, Helianthus annuus L., heterosis

Abstract Background Pennycress (Thlaspi arvense L.) is an annual herbaceous plant of the Cruciferae family that has attracted attention as an oil crop and interseeded cover crop. We collected seeds of pennycress from five provenances in Northeast China, compared their characteristics, i.e. oil content, fatty acid composition, physical, chemical and antioxidant properties, their correlations with environmental factors were also analysed. Results There were significant differences in the seed characteristics, oil content, quality indicators and composition among different provenances (P < 0.05). The 1000-seed weight ranged from 0.80 to 1.03 g; seed oil content from 28.89 to 42.57%; iodine from 79.19 to 99.09; saponification value from 186.51 to 199.60; peroxide value from 0.07 to 10.60; and acid value from 0.97 to 13.02. The range of seed oil colours were 66.53–78.78 (L*), 4.51–10.29 (a*), and 105.68–121.35 (b*). Erucic acid (C22:1) was the fatty acids with the highest content in pennycress seed oils (31.12–35.31%), followed by linoleic acid (C18:2 16.92–18.95%) and α-linolenic acid (C18:3 14.05–15.34%). The fatty acid 8,11,14-eicosatrienoic acid (C20:3) was detected for the first time in seed oils from Beian city, Panshi city and Kedong county, with contents of 1.13%, 0.84% and 1.03%, respectively. We compare and report for the first time on the radical-scavenging activity of the seed oils of pennycress. The EC50 values of the DPPH radical-scavenging activity and ABTS+ radical-scavenging activity of the seed oils from different provenances were 8.65–19.21 mg/mL and 6.82–10.61 mg/mL, respectively. The ferric ion reduction antioxidant capacity (FRAP) ranged from 0.11 to 0.30 mmol Fe2+/g, which is equivalent to 4 mg/mL FeSO4 of pennycress seed oils. Conclusions There was a significant correlation between seed characteristics and changes in geographical factors. With increasing longitude, the thickness of seeds, 1000-seed weight, and seed oil content increased, while the acid and peroxide values of the seed oil decreased. As the latitude increased, the 1000-seed weight and seed oil content increased, while the seed oil peroxide value decreased. Furthermore, mean annual temperature and annual rainfall are the two key environmental factors affecting the quality of pennycress. Graphical Abstract

AbstractDuring two growing seasons there were studied 11 sunflower breeding lines and their 30 analogues obtained via backcrossing, chemical mutagenesis and selected as natural mutants. The variability of such agronomic traits as crop yield, seed oil content, 1,000 seed weight, plant height, leaf and petiole size, number of leaves and branches, and head diameter was investigated. The traits of crop yield, leaf size, number of branches were the most variable, whereas the most stable were 1,000 seed weight, seed oil content, plant height, and the number of leaves. The influence of mutant genes which control ray flower color and shape, leaf color and shape, dwarfness, number of leaves and ray flowers, and shape of bracts on the manifestation of important agronomic traits was estimated. No negative impact of the genes of ray flower color and shape and leaf color was noticed. The gene of fringed leaf margin reduced plant height while the gene of erect petiole increased development of that trait. The genes of dwarfness can negatively influence seed oil content and 1,000 seed weight.

Sowing Dates

In order to elucidate the effect of sowing date on the yield and yield components of oilseed rape (Brassica napus L.), three varieties - Tower, Rafal and Global - were sown from 7 November to 22 December 2000-01 on four dates at an interval of 15 days in the Dezful region of Iran. A split-plot design based on randomized complete blocks with four replications was used in the experiment, where the sowing dates and cultivars formed the main and subplots, respectively. Variables including plant height, axillary branches/plant, pods/plant, seeds/pod, single seed weight, biomass, seed oil content and seed yield were measured. The soil of the experimental site had a loamy clay texture. The site had 250 mm annual precipitation and was located in the semi-arid zone. The results showed that the sowing date had a highly significant effect on morphological characteristics, yield components, oilseed rape yield and seed oil content. A delay in the sowing date caused a reduction in all the yield components especially in pods/plant, and in oilseed yield, which dropped from 285 g m-2 when sown on 7 November to 135 g m-2 when sowing was delayed to 22 December. Variations in sowing dates had different effects on the individual yield components, with pods/plant, seeds/pod and single seed weight decreasing to the greatest extent. The significant effect of variety on all characters with the exception of single seed weight indicated that there were genetic differences between the studied cultivars. Oilseed yield showed significantly positive correlations with pods/plant (r=0.93), single seed weight (r=0.83) and seeds/pod (r=0.66). The results of path analysis showed that pods/plant and seeds/pod had the highest positive and negative effects on oilseed yield, respectively. Finally, considering the susceptibility of pods/plant to variations in sowing date and the importance of this character in the size of the oilseed yield, a delay in the planting date in the Dezful region was found to reduce the oilseed yield through a reduction in pods/plant.

The most important criteria for introducing new confectionary hybrids into the production is high protein yield. Path coefficient analysis was used to obtain information on direct and indirect effects of studied traits (seed oil content, kernel oil content, seed yield, kernel protein content, mass of 1000 seeds, kernel ratio and hull ratio) on protein yield. The research was conducted during three vegetation seasons, on 22 experimental confectionary sunflower hybrids created in the breeding program at the Institute of Field and Vegetable Crops. Strong and very strong correlations were found among the largest number of examined traits. A weak negative interdependence was determined between kernel oil content, kernel protein content, mass of 1000 seeds, hull ratio, and protein yield using the analysis of simple correlation coefficients. Positive but weak correlation was determined between protein yield and seed oil content, and kernel ratio. Very strong positive correlation was determined between protein yield and seed yield (0.468**). The seed oil content had a very strong direct negative effect on protein yield (DE=-0.734**). The mass of 1000 seeds had a weak negative direct effect on protein yield. Kernel protein content and kernel oil content demonstrated a weak direct positive effect on protein yield. Path coefficient analysis of protein yield showed a very strong positive direct effect of kernel ratio (DE=1.340**), seed yield (DE=0.657**) and hull ratio (DE=0.992*). These findings confirm the effect of seed yield, kernel ratio, and hull ratio on protein yield, and their importance as the selection criteria in confectionary sunflower breeding.
