Abstract
During 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.
Résumé
Pendant deux saisons de croissance y ont été étudiés 11 lignes de tournesol de reproduction et leurs 30 analogues obtenus par croisement en retour, la mutagenèse chimique et sélectionné comme mutants naturels. La variabilité de ces caractères agronomiques comme le rendement des cultures, la teneur en huile des graines, le poids de 1000 graines, hauteur de la plante, la feuille et la taille pétiole, le nombre de feuilles et de branches, et le diamètre de la tête a été étudiée. Les traits de rendement des cultures, la taille des feuilles, numéro des branches étaient le plus variable, alors que les plus stables ont été le poids de 1000 graines, teneur en huile de la graine, hauteur de la plante, et le nombre de feuilles. L‘influence des gènes mutants qui contrôlent rayons couleur de la fleur et la forme, la couleur et la forme des feuilles, nanisme, le nombre de feuilles et de fleurs de rayons, et la forme de bractées sur la manifestation de traits agronomiques importants a été estimé. Aucun impact négatif des gènes de rayons couleur de la fleur et la forme et la couleur des feuilles a été remarqué. Le gène de la feuille franges marge réduite hauteur de la plante tandis que le gène de l‘érection pétiole augmenté développement de ce trait. Les gènes de nanisme peuvent influencer négativement la teneur en huile des graines et le poids de 1000 graines.
Resumen
Durante dos temporadas de cultivo se estudiaron 11 líneas de mejoramiento de girasol y sus 30 análogos obtenidos mediante retrocruzamiento, mutagénesis química y seleccionado como mutantes naturales. La variabilidad de tales características agronómicas como el rendimiento del cultivo, contenido de aceite de la semilla, peso de 1000 semillas, altura de planta, tamaño de la hoja y del pecíolo, número de hojas y ramas, y el diámetro de la cabeza fue investigado. Los rasgos de rendimiento de los cultivos, tamaño de la hoja, el número de ramas eran las más variables, mientras que los más estables eran 1.000 peso de la semilla, el contenido de aceite de semilla, altura de la planta, y el número de hojas. La influencia de los genes mutantes que controlan rayos color de la flor y de la forma, el color y la forma de la hoja, enanismo, número de hojas y flores de rayos, y la forma de brácteas en la manifestación de importantes características agronómicas se estimó. Sin impacto negativo de los genes de rayos color de la flor y la forma y color de las hojas se notó. El gen de la hoja con flecos margen reducido altura de la planta, mientras que el gen del pecíolo erecto aumentó desarrollo de ese rasgo. Los genes de enanismo pueden influir negativamente en el contenido de aceite de la semilla y peso de 1000 semillas.
