VARIATIONS IN THE AGRONOMIC AND QUALITY CHARACTERISTICS OF DOMESTIC AND FOREIGN SAFFLOWER (Carthamus tinctorius L.) GENOTYPES

Sabri ERBAS, Muhammet TONGUC, Arif SANLI

Abstract

The present study was carried out to determine the agronomic and quality characteristics of domestic and foreign safflower (Carthamus tinctorius L.) genotypes in the 2011-2012 growing season in Isparta. In the study, 39 safflower genotypes were used as the plant material. The highest 1000 seed weight and hull content were detected in Ziyang. Arizona SC III was determined as the genotype with the lowest 1000 seed weight, hull content, seed yield, and oil yield. The highest seed yield was recorded in UC-1 (215.9 kg da-1 ). Oil contents of the genotypes ranged from 22.6 to 33.8% on average and Arizona SC III, Oleic Leed, Centennial, Finch, Ole, S-517, Enana and Leed were determined as the genotypes with the highest oil content. Variation for oleic acid was between 11.1 and 68.3% in 2011 and between 12.0 and 71.6% in 2012. Linoleic acid content varied between 18.0 and 74.7% in 2011 and between 14.2 and 73.9% in 2012. Montola 2000, Ole, UC-1, NO 55-663 and S-517 were found to contain more than 60% oleic acid. Both performances of the genotypes used in the study could further examined by cultivating in different locations and a successful hybridization program compatible with the desired goals of breeding may be drawn up using wide variations reported among the examined morphological and agronomic characters.

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.
