Heritability estimates and the variation of pomological traits, total phenolic compounds, and antioxidant capacity in two apricot progenies

Abstract

Even though pomological traits are important in fruit breeding for quality, antioxidant capacity and the total content of phenolic compounds have also gained importance, together with a rising awareness of their health benefits. As a result, this study was conducted to evaluate the variation and heritability levels of antioxidant capacity and total phenolic compounds, as well as pomological traits in 'Hacıhaliloğlu' × 'Stark Early Orange' and 'Çataloğlu' × 'Stark Early Orange' apricot crosscombinations based on phenotypic assessments of fruit samples. The results indicated significant differences among F 1 progenies in the samples involved in the study. Broad-sense heritability coefficients ranged from 0.59 to 0.98 in the combinations examined. Parent-offspring regression coefficients for antioxidant capacity and total phenolic compounds were calculated to be 0.433 and 0.164, respectively. The results of the study can be useful in deciding selection strategies and choosing parents in relevant breeding programs.

Detection of Quantitative Trait Loci Controlling the Content of Phenolic Compounds in an Asian Plum (Prunus salicina L.) F1 Population

“…There are few works reporting heritability values for stone fruits. Recently, Karaat and Serçe (2020) have determined moderate broad-sense heritability values for total phenolic compounds and antioxidant activity in apricot progenies (14 and 43%, respectively), although higher values have been found in raspberry (narrow-sense: 48-54%; Connor et al, 2005) and blueberry progenies (38-56%; Connor et al, 2002). These data indicate that, in the mentioned Prunus species, heritabilities are lower than in other Rosaceae and Ericaceae fruits.…”

Evaluation of ‘Alata Yıldızı’בBebeco’ apricot hybrids in terms of phenology, plant, and fruit quality characteristics

“…Ayrıca,Cross et al (2018), kayısı melezlerinde renk oluşumunda kullanılan ebeveyn kombinasyonuna göre renk dağılımında önemli farklılıklar olduğunu ve renk oluşumunun çok gen tarafından kontrol edildiğini bildirmişlerdir. Benzer olarak,Karaat & Serçe (2020), kayısı melezlerinin renk özelliği bakımından farklılık gösterdiğini ve bu özelliğin yıllara göre değiştiği(Salazar, 2013) ifade edilmiştir.…”
