INVESTIGATION OF SOME COMMON WHEAT GENOTYPES BY YIELD-RELATED TRAITS FOR KAHRAMANMARAŞ LOCATION IN TURKEY

Tevrican DOKUYUCU , Aydın AKKAYA', Mevlut AKÇURA

Abstract

This research was carried out to investigate some common wheat genotypes by yield-related traits, from 1997 to 2000, for three years, in Kahramanmaras, located in East- Mediterranean region. In research. 299 common wheat (Triticum aestivum L.) genotypes were evaluated for head length (HL), spikelet number per head (SN/H), grain number per head (GN/H), grain weight per head (GW/H) and 1000-grain weight (1000-GW) using statistical parameters. Genotypes were distributed in to five groups for each trait. According to results, ranges were changed 5.4 cm and 14.5 cm for HL, 9.0 and 25.0 spikelets for SN/H, 8.0 and 69.4 grains for GN/H, 0.17 g and 2.48 g for GW/H, 12.0 g and 56.4 g for 1000-GW. Standard deviations were high for GN/H and 1000-GW, and were low for GW/H, HL and SN/H. Means were also 8.4 cm for HL. 17.0 spikelets for SN/H, 35.6 grains for GN/H, 1.26 g for GW/H, 35.3 g for 1000-GW. Coefficients of variation were only high for GW/H in the second year and it was in the confidence limits for other trits in the experiement years. Distribution of genotypes was also different due to traits and there were more genotypes in-group 3 for HL, SN/H and GN/H, in group 4 for GW/H and group 2 for 1000-GW. GN/H and 1000-GW with higher SD and CV values in confidence limits were hopeful traits for a selection work in the region.

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.
