Title : Phenotyping of segregating generations derived from sunflower interspecific crosses (H.annuus) and (H. argophyllus)
Limited water availability suggests that in future water insufficiency will be norm which leads to the major losses in yield and yield components. Management under these conditions as compare to unlimited water availability may result in reducing yield losses. Study was started to improve crop production by introgression of drought tolerant traits from wild sunflower to cultivated type of sunflower resultantly material of filial generations F1, F2, and F4 is analyzed on the basis of some phenotypic and physiological indicators. When compare to parents UCA-16 and Argo-5-IV these segregating populations have mean value in F1 and when compared by leaf parameters like leaf rolling, hairiness, leaf colour and waxes produced by cuticular layers behaved differently. In selected material of successive generations on cell membrane injury, achene yield and single head type will be further grown by keeping ultimate objective of drought tolerant inbred line.
