ASSESSMENT OF EARLY GENERATION PERFORMANCES OF DURUM WHEAT (Triticum durum L. Desf.) MUTANT LINES
O. BİLGİN, İ. BAŞER, K.Z. KORKUT, A. BALKAN
Abstract
A total of 96 mutant lines were sown in augmented design with 4 check varieties without replications in 6 blocks. When mutants and control genotypes in the Ms generation were investigated for six characters, a considerable number of mutants within the desired characters were obtained. Application of mutation doses resulted in significantly short genotypes among the selected mutant genotypes in the M5. The majority of M4 mutant lines had suitable genotypes in terms of plant height and heading, test weight and a thousand kernel weights.

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

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.
