Breeding barley for quality in Turkey

Abstract

We evaluated a total of 411 genotypes, including 334 breeding lines with 77 checks from Barley (Hordeum vulgare L.) Breeding Program of Turkey (BBPT), based upon their grain yield (GY) and quality traits (namely protein content-PC, acid detergent fiber-ADF, thousand kernel weight-TKW, kernel size-KS and test weight-TW), during the 5 consecutive cropping seasons, from 2007-2008 to 2011-2012. Broad-sense heritability (H) values for quality traits were moderate (0.57-0.65), while it was low (0.43) for grain yield. Accordingly, grain physical features (namely TW, KS and TKW) were positively significantly correlated with GY, but negatively significantly correlated with PC. Results of our study showed that selection for GY and quality traits was less efficient than we expected, due to undesirable multi-variate correlations such as GY vs PC and low to moderate H values. Therefore, we tried to put suggestions forward to the BBPT, by following discussing about our ability to select for high GY and acceptable quality in barley.

Yüksek Kaliteli Kışlık Yulaf Çeşitlerinin Geliştirilmesi

“…With this dynamic process, the genetic component of GEI is made more predictable. But its environment component is entirely unpredictable (Kaya and Ayranci, 2016;Yan et al, 2016;Sadras et al, 2019).…”

“…Both genotype and environment affect quality characteristics because quality features are under the control of quantitative genetics (Kaya and Ayranci, 2016). The protein content (PC) values measured in our oat breeding trials varied between 11.24% and 15.39%.…”

Physiological and Genetic Variation of Hordeum vulgare L. and Triticum aestivum L. Lines Planted in Turkey

“…Barley is an annual plant and has great adaptability for plenty of stress factors. By this way, it has a wide geographical area to grow and be distributed in the world and in Turkey (Baik and Ullrich, 2008;Kaya and Ayranci, 2016). It is among the most produced cereals in Turkey following wheat.…”
