COMBINING ABILITY AND GENE ACTIONS FOR GLUTEN RHEOLOGICAL TRAITS OF “LINE×TESTER” BREAD WHEAT HYBRIDS

Imren KUTLU , Yasar KARADUMAN

Abstract

The fast and reliable measurement techniques in determining bread-making quality such as GlutoPeak parameters is need in a cereal quality breeding programs. Therefore, this study intended to investigate gene actions in the inheritance of gluten rheological properties measured by Glutopeak tester in 28 hybrids of “Line×Tester” bread wheat and their 11 parents based on knowledge of combining ability. There was a prominence of non-additive gene effects for all the traits examined. Well-performed parents such as DH20 and Harmankaya-99 were good combiners for almost all examined traits. “DH16×Bezostaja-1”, “DH20×Bezostaja1”, “DH20×Harmankaya-99”, “DH21×Altay-2000”, and “DH22×Kate A-1” were promising combinations based on their SCA effects. There may be an opportunity to select the best genotypes in the F2 generation for protein rate, sedimentation value and GlutoPeak parameters such as peak maximum time (PMT) and maximum torque (AM and PM) considering the little increase in narrow sense heritability. This first report, which sheds light on the genetic analysis of GlutoPeak parameters, should be supported by studies that will examine the Glutopeak properties in different segregation generations of hybrids with different originated parents.

Effects of Different Water Stress Levels on Biomass Yield and Agronomic Traits of Switchgrass (Panicum virgatum L.) Varieties under Semi-Arid Conditio

Erdal GONULAL, Suleyman SOYLU, Mehmet SAHIN

Abstract

A field experiment was conducted in the Wielkopolska region at the Gorzyń Research Station, Poland (52.34°N, 15.54°E) in Central Europe. The study was conducted over a 3-year period (2017, 2018, 2019) as a two-factorial design with four replications in the RCBD. The aim of the research was to determine the effect of the cultivar (‘Bolero’, ‘Tytan’) and the inoculation (Nitragina–seeds inoculation, Nitroflora I–seeds inoculation, Nitroflora II–soil inoculation, HiStick® Lupin–seeds inoculation) on plant development, seeds chemical composition and yielding of narrow-leaved lupin. The weather conditions and experimental factors significantly influenced on productivity of narrow-leaved lupin ‘Tytan’. Drought during the growing season reduced seeds and protein yields. After inoculation of HiStck the seeds yield was significantly greater by 12.4% (p < 0.01) and the protein yield after application of Nitroflora I or HiStick by 13.9% (p < 0.01) and 19.2% (p < 0.01), respectively. Correlation coefficients showed strong relations between number of pods and seeds per plant in both cultivars regardless of the inoculation variant, however the strongest relations in both cultivar were proved on HiStick treatment.
