Field experiments were carried out during 2005-2007 in order to study the genetic structure of a hybrid sunflower population, to identify the parents and crosses showing superior general and specific combining ability and finally to evaluate F1 hybrid vigour. Six artificial hybrids were created using 3 CMS and 2 restorer lines in sunflower (Helianthus annus L.) According to the results, the ratios of GCA:SCA variance were lower than 1 for plant height and head diameter in the both years; for number of seeds per head and 1000 seed weight in 2007 and for seed yield in 2006. For all these characters, non-additive effects were more effective than the other types of polygenetic effects. The additive gene actions were significant for 1000 seed weight and number of seeds per head in 2006 and for plant height and seed yield in 2007, since the ratios of GCA:SCA variances for these characters were greater than 1. The parental lines CMS 10 and RHA 10 proved to be good combiners having the high...

Seed yields of 14 soybean genotypes were evaluated in four locations i.e. Adana, Şanlıurfa, Antalya and İzmir under second crop conditions through summer seasons from 2014 to 2016. The study aims to estimate the stability parameters in terms of seed yield of 14 soybean genotypes by using different stability analysis methods across eleven environmental conditions and to study interrelationships among these stability methods. The analysis of variance for seed yield revealed that the genotypes and the environments as well as the genotype x environment interactions (GEI) were statistically significant at P<0.01. Environmental effects were contributed 51.04% to the total sum of squares whereas GEI and genotype effects were 20.8% and 2.59%, respectively. According to most stability methods, BATEM 223, BATEM 306, BATEM 317 and KASM 02 were determined to be stable genotypes. These genotypes demonstrated superior adaptability with high yield performances in many environments. Results of c...

The effects of three row spacings (17.5, 35.0 and 52.5 cm) and four seeding rates (100, 200, 300 and 400 viable seeds m-2) on seed yield and some yield components of winter oilseed rape (Brassica napus L.) were evaluated under rainfed conditions in Bursa, Turkey in the 2005-2006 and 2006-2007 growing seasons. Row spacing and seeding rate significantly affected most yield components measured. The number of plants per unit area increased with increasing seeding rate and decreasing row spacing. Greater plant heights were obtained from narrow row spacings and higher seeding rates. Narrow row spacings and higher seeding rates reduced the number of primary branches and the number of pods per terminal raceme. Also, the number of seeds per pod and 1000-seed weight were not affected by either row spacing or seeding rate. In contrast, the number of pods per plant clearly increased with increasing row spacing but decreased with increasing seeding rate. The highest seed yields were obtained for...

Field experiments were conducted to evaluate the yield and yield components of twelve soybean genotypes as a forage and a grain crop in Marmara Region of Turkey in 2003-2004 growing seasons. Forage and dry matter yield and yield components at one vegetative stage (V5) and two reproductive stages (R2, and R4) and seed yield was determined in all soybean genotypes. The experiments showed that the harvest stages had signifi cant effects on forage and dry matter yield, and R4 reproductive stage had the highest forage and dry matter yield. Dry matter partitioning of soybean plant parts was greatly affected by harvest stages, while the genotypes had little effect on dry matter partitioning of soybean plant parts. There were statistically signifi cant differences between soybean genotypes in seed yield, but the differences were small. The correlations between forage and dry matter yield and seed yield were not statistically signifi cant.

The objectives of this study were to evaluate dry matter (DM) yield and seed yield of six leafed and semi-leafless pea (Pisum sativum L.) genotypes, and to compare them for these traits. Evaluation of genotype x environment (G x E) interaction, stability and cluster analysis were also carried out at eight diverse locations with typical Mediterranean and Mediterranean-type climate during the 2001-2002 and 2002-2003 growing seasons. Significant differences were found among the pea genotypes for DM and seed yield on individual years and combined over years, and in all locations. All interactions which related to G x E interaction showed significance (P>0.001) for DM and seed yield. The highest yield (4789 kg/ha) was obtained from the leafed genotype 'Urunlu'. However, stability analysis indicated that for DM yield, the leafed genotypes 'Golyazi' and 'Urunlu' should be grown in low yielding and high yielding environments, respectively. Cluster analysis, based ...

Three different soybean [Glycine max (L.) Merr.] cultivars (A-3127, Derry, and Yemsoy) were evaluated for dry matter (DM) yield, plant components, and crop growth rate (CGR) at different row spacings and harvesting stages in 3 locations with Mediterranean-type climate in a split-split plot design with 3 replications in 2009 and 2010. In addition, crude protein (CP), crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN), and relative feed value (RFV) of harvested forage soybeans were determined at the Bursa (Turkey) location. Increased row spacings significantly reduced DM yield at all locations. Combined over other main effects, the 25-cm row spacing produced 35% more DM yield than the 75-cm row spacing. Row spacings greatly affected DM yield at the R5 and particularly the R7 stage, but this effect was minimal at the R1 stage. The forage-type cultivar Derry produced significantly higher DM yield in all locations, parti...

Immature embryo culture of sunflower (Helianthus annuus L.) was studied for shortening the generation time in breeding programs. The seed development from pollination to maturity in sunflower takes 50-60% (60 days) of the life cycle duration (120-150 days). This technique allows the production of fertile plants from immature embryos of 11 sunflower genotypes. Immature embryos of 10-12 days after pollination were dissected from seed grown plants (SGP), were transferred into MS medium allowing shoot and root development for 5-10 days. Young plantlets were transferred to soil, developed to maturity and were then self pollinated and set seed. The first cycle of immature embryo raised plants (IERP) was obtained. The four cycles of IERP were obtained from immature embryo culture technique in contrast to one generation per year with conventional breeding. The majority of cultured embryos developed into vigorous plantlets with 3-6 leaves. Out of 1320 immature embryos, the average response o...

This study was carried out to investigate the yield response of 2 soybean (Glycine max (L.) Merrill) cultivars to different planting dates and plant populations and to examine the relationships of seed yield with leaf area index (LAI) and total dry matter (TDM) during the vegetative and reproductive periods for planting dates, plant populations, and cultivars. Two soybean cultivars, A-3127 (early maturity group, MG-III) and 1530 (late maturity group, MG-IV), were planted in 2 planting dates; mid-April and mid-May during 2005 and 2006 at high (660,000 plant ha-1) and low (330,000 plant ha-1) plant populations. Plantings in mid-April increased seed yield by about 10.0%-13.5% compared with mid-May plantings. High plant populations produced 17.7% higher seed yield than the low population. Seed yield of the late maturity cultivar was more than that of the early maturing cultivar. Significant and positive relationships between seed yield and LAI were evident for planting dates at all grow...

The heterosis and combining ability of four rapeseed (Brassica napus L.) genotypes were estimated using diallel crosses. An experiment was conducted at Uludag University, Bursa, Turkey, during the 2005-2006 and 2006-2007 growing seasons using 4x4 full diallel crosses. All of the 12 F1 hybrids and their parents were planted in a randomized complete block design with three replications. The data obtained from the experiment were subjected to an analysis of variance. The analysis of variance indicated significant differences among parents and their hybrids in the F1 generation for all the characters studied except for 1000-seed weight, which was non-significant. Positive better-parent heterosis for seed yield per plant were found in all 12 hybrids tested. An analysis of the components of combining ability showed that general combining ability (GCA) and reciprocal combining ability (RCA) were highly significant (p ≤ 0.01) for plant height and number of pods per main raceme, whereas spec...

ABSTRACT The effects of four row spacings (17.5, 35.0, 52.5 and 70.0 cm) and five seeding rates (50, 100, 200, 400 and 800 viable seeds m−2) on seed yield and some yield components of forage turnip (Brassica rapa L.) were evaluated under rainfed conditions in Bursa, Turkey in the 1998–1999 and 1999–2000 growing seasons. Plant height, stem diameter, pods/terminal raceme, total pods/plant, seeds/pod and primary branches/plant were measured individually. The number of plants per unit area was counted and the lodging rate of the plots was scored. The seed yield and 1000-seed weight were also determined. Row spacing and seeding rate significantly affected most yield components measured. The number of plants per unit area increased with increasing seeding rate and decreasing row spacing. Plant height was not greatly influenced by row spacing and seeding rate, but higher seeding rates reduced the number of primary branches and the stem diameter. The number of pods/main stem was affected by row spacing and but not by the seeding rate. Also, the number of seeds per pod was not affected by either the row spacing or the seeding rate. In contrast, the number of pods per plant clearly increased with increasing row spacing, but decreased with increasing seeding rate. The plots seeded at narrow row spacings and at high seeding rates were more sensitive to lodging. Seeding rate had no significant effect on seed yield in both years. Seed yield was similar at all seeding rates, averaging 1151 kg ha−1. However, row spacing was associated with seed yield. The highest seed yield (1409 kg ha−1) was obtained for the 35.0-cm row spacing and 200 seeds m−2 seeding rate combination without serious lodging problems.
