Mapping one of the 2 genes controlling lemon ray flower color in sunflower (Helianthus annuus L.).
In an F2 population of 120 plants derived from a cross between 2 breeding lines with yellow ray flowers, we observed 111 plants with yellow-colored and 9 plants with lemon-colored ray flowers. The segregation pattern fits a 15:1 (chi2(15:1) = 0.32, P > 0.5) ratio, suggesting that the lemon ray flower color is conditioned by 2 independent recessive genes that had been contributed individually by...
متن کاملPLANT GROWTH REGULATORS INDUCED DROUGHT TOLERANCE IN SUNFLOWER (Helianthus annuus L.) HYBRIDS
Present study was conducted to investigate whether plant growth regulators viz. salicylic acid and ascorbic acid can alleviate the adverse effects of drought stress on germination and seedling growth of two sunflower hybrids (Hysun-33 and Hysun-38). Two (-0.06 MPa and -0.12 MPa) levels of drought stress were created by adding different concentrations of (PEG8000) polyethylene glycol in growth m...
متن کاملVariability in antioxidant activity and phenolic profile in different parts of sunflower (Helianthus annuus L.) genotypes
Sunflower (Helianthus annuus L.) is largely consumed in Iran as an oleaginous and confectionery product. In this study, the total phenolic and flavonoid contents, antioxidant activity and phenolic composition in different parts of the seeds from six sunflower genotypes were investigated. The antioxidant activity of extract was evaluated by different assays. The total phenolic and flavonoid cont...
متن کاملDetermination of drought tolerance related traits in Helianthus argophyllus, Helianthus annuus, and their hybrids
Drought is a major constraint for sunflower (Helianthus annuus) production worldwide. Drought tolerance traits have been identified in the related wild species Helianthus argophyllus. This study was initiated to develop sunflower drought-tolerant genotypes by crossing cultivated sunflower with this species and analyze drought tolerance traits in the H. annuus and H. argophyllus populations, H. ...
متن کاملCytological Characterization and Pollen Viability Studies in the Interspecific Hybrids between Helianthus Annuus and Helianthus Maximiliani
The present investigation was undertaken with a view to study Cytological behavior of F1 interspecific hybrids of diploid wild perennial species Helianthus maximilini (2n = 34) and with cultivated sunflower Helianthus annuus (2n = 34) prebred line M-106. The interspecific hybrids have annual life cycle with the diploid somatic chromosome number thirty four. Chromosome association represented by...
