Improvement in the Branching Mutant of Helianthus annuus by Mass Selection

Gehan G. Mostafa

Abstract:
Background: Sunflowers are widely grown commercially for the oil and they are good lasting as cut flowers. The study aimed to improve the branching mutant of Helianthus annuus for their No. of inflorescences per plant as ornamental plant. Methodology: Three cycles of mass selection were applied from 2011 to 2013. Evaluation of their performance during two seasons was done during 2014 and 2015. Results: A gradual increase was found during the three cycles of mass selection (C1, C2 and C3) for most studied traits in both seasons as well as in combined analysis. No significant differences were found in the No. of florets per inflorescence, while a slightly increase was obtained. Mass selection had negative effect in the earliness of flowering. Number of inflorescences per plant was increased by 16.3, 19.7 and 61.4% for C1, C2 and C3, respectively. Positive and high correlation coefficients were found between the No. of inflorescences per plant and other traits except for the No. of seed per main head where moderate correlation was extended (0.66). Conclusion: Mass selection was a successful method to improve the branching mutant of Helianthus annuus and produce a new cultivar with better characteristics as ornamental plants.
