Özet

This study aimed to determine the genetic heritability of earliness and fruit quality characteristics in five apricot progenies. The study established the contribution of heterosis as well as the genetics of parents involved in crosses to trait heritability. The data are suitable for developing breeding strategies for apricot improvement. The phenological and fruit quality characteristics of the ‘Alata Yıldızı’ × ‘Bebeco’ (AY × B), ‘Çağataybey’ × ‘Ninfa’ (ÇB × N), ‘Çağataybey’ × ‘Stark Early Orange’ (ÇB × SEO), ‘Şahinbey’ × ‘Precoce de Tyrinthe’ (ŞB × T), and ‘Alata Yıldızı’ × ‘Ninfa’ (AY × N) progenies were evaluated. Considerable differences were found among F1 progenies depending on the parents involved. Broad-sense heritability coefficients ranged from 0.27 to 0.99 in the crossbreeding combinations. The AY × B and ÇB × SEO combinations were promising in terms of early flowering and fruit ripening with negative heterosis. The high correlation and regression coefficients between mid-parents and mean progenies, heritability, and heterosis ratio suggest that the use of appropriate parents in apricot breeding programs is critical.
