Intra-population recurrent selection in sunflower (Helianthus annuus L.)

, : Intra-population recurrent selection in sunflower (Helianthus annuus L.). Proceedings of the 13th International Sunflower Conference Volume 2, Pisa, Italy, 7-11 September 1992: 1251-1256

A French open pollinated population, divided into 2 subpopulations (A = original (control) and B = irradiated with 1.8 kR gamma irradiation), and 300 half-sib families of each subpopulation were evaluated for capitulum weight, height and diameter, achene weight, and plant height during 1992. Hybrids Conti 112 and Contisol were used as controls. Plant and capitulum height were strongly negatively affected by irradiation, whereas capitulum diameter was not.
