Safflower is an underutilized and minor oilseed crop that received less attention from the scientific community compared to other oilseed crops like soybean and sunflower. Exploring the genetic basis associated with agronomic traits is crucial for markerassisted breeding of safflower. A genome-wide association study was conducted using a total of 12,232 DArTseq markers to identify the marker-trait association for important agronomic traits in an international safflower panel derived from 26 different geographical countries of the world. Statistically significant genotypic effects (p < 0.05) were observed across mean data of both locations (Pakistan and Turkey). Moderate to high heritability estimates were observed for the studied traits. Studied material showed higher performance for all traits except seeds per capitulum in Pakistan compared to Turkey. Phenotypic diversity for important agronomic traits, such as plant height (60.08 to 121.48 cm), capitula per plant (8.7 to 80.4), seeds per capitulum (15 to 42.05), and seed yield per plant (4.85 to 51.02 g), was illustrated. Seed yield per plant showed a highly significant and positive correlation with capitula per plant (0.4985***). Constellation plot analysis resulted in four groups, i.e. A, B, C, and D. Genotyping by sequencing resulted in 12,232 DArTseq markers being used for the investigation of marker-trait association through mixed linear model (Q + K) approach. DArT-38077549 showed significant association with capitula per plant, while two markers (DArT-22763576, DArT-22763253) were associated with plant height. A total of two markers (DArT-38079422, DArT-100043360) were associated with seeds per capitulum. A total of five DArTseq markers showed significant association with seed yield per plant and maximum variation was resulted by DArT-100004992. The results of this study provide a new insight to understand the genetic basis associated with agronomic traits in safflower. We envisage that significant markers identified through this investigation may be applicable in future safflower marker-assisted breeding programs.

Developing high yielding safflower cultivars with good adaptation to diverse environmental conditions can improve production in terms of seed yield and reduce the deficiency in edible oil. The genetic variability that exists among and within populations for desirable agronomic traits can be used to develop elite cultivars. A total of 94 safflower accessions from 26 different countries were used in this study to evaluate morphoagronomic performance, determine the pattern of similarity centers, and identify the best performing accessions by conducting 2 field experiments in Pakistan and Turkey using augmented design. Genetic diversity for important yield and yield traits was described …

The effect of water reduction stress on photosynthetic efficiency and the agronomic traits of 10 bread winter wheat cultivars were investigated, with an aim to develop breeding methods for improving wheat drought tolerance. In the 2008 and 2009 crop seasons, the trial was grown in vegetative pots according to the method of a 2-factorial experiment (cultivar and treatment) as a randomized complete block with 3 replications. The stressed version of the treatment was exposed to mild water reduction short-term stress 3 times (at the end of tillering stage, at the flag leaf to beginning of heading stage, and at the …

Tomato is one of the most widely produced and consumed vegetable crops worldwide. Plant breeders have usually focused on improvement of horticulturally important traits such as yield, fruit size, shape and colour. With increased attention on human health, however, plant breeders also consider the improvement of health-related traits of fruits and vegetables such as antioxidant characters. In the present study, genes controlling both health-related and horticulturally important traits were mapped in the tomato genome using 152 Lycopersicon hirsutum BC_2F_2 individuals. For this aim, all plants were phenotypically and genotypically characterised and a total of 75 QTLs were identified for all …
Hybrid Vigor In Common Wheat (Triticum Aestivum L.), Köksal Yağdi, Şenay Karan
Hybrid Vigor In Common Wheat (Triticum Aestivum L.), Köksal Yağdi, Şenay Karan
Turkish Journal of Agriculture and Forestry
This research was carried out at the experimental plots of the Field Crops Department of Agriculture Faculty, Uludağ University, during 1994-1996. Thirteen strains of common wheat obtained from the Prof. Dr. Osman Tosun Gene Bank were used as parent material for seven combinations of hybridirazations. In the F 1 populations belonging to the abovementioned combinations, plant height, spike height, spikelet number per spike, kernel number and kernel weight per spike and 1000-kernel weight were determined and the hybrid vigor was calculated. Positive and significant differences varying among the combinations were found in the F 1 plants with higher values than …
