Abstract

In this review, the use of gibberellic acid in sunflower breeding was discussed. The hand emasculation in sunflower is difficult task and after obtaining many inbred lines they need to be crossed easily to find F1 hybrids. For this reason, When 75-100 ppm GA3 in H2O is applied to sunflower heads (at star stage), 100 % sterility can be obtained easily without emasculation. Today's sunflower breeders use this Chemical to get sterility, before the lines converted into Cytoplasmic Male Sterility.

Özet

Bu derlemede ayçiçek ıslahında giberelik asid kullanımı tartışıldı. Ayçiçeklerinde emaskülasyon zor bir görevdir ve bir çok kendilenmiş hat elde ediltikten sonra Fİ hibridlerin bulunabilmesi için kolaycılıkla çaprazlanmalan gerekmektedir. Bu nedenle, suda 75-100 ppm GA3 ayçiçek tablalarına (yıldız safhası) kullanıldığında emaskülasyona ihtiyaç duymadan % 100 sterilite elde edilebilir. Bugünün ayçiçek ıslahçıları steriliteyi elde etmek için bu kimyasalı kendilenmiş hatları sitoplazmik erkek kısırlığına dönüştürmeden kulanmaktadırlar.
