Double crop agriculture is a great advantage for the coastal Mediterranean climate. Although a number of soybean varieties have been recommended for cultivation, the information on the stability for double cropping is lacking for the agro-climatic conditions of Mediterranean coastal zone. Ten high-yielding advanced soybean [Glycine max (L.) Merr] lines and four registered soybean varieties having maturity group III and IV (ARISOY, ATAEM7, BRAVO and NOVA) were evaluated for double cropping in different regions and years (2014, 2015 and 2016 in Izmir-Bornova, 2015 and 2016 in Antalya-Aksu). The F test was first applied to check differences of the deviation variances from the zero. In addition, statistics of ecovalance (Wi 2 ) and stability variance (σi 2 ), estimating the contribution of a genotype to total Genotype x Environmental interaction (GxE), were estimated. As a result of this research, two different conclusions were determined. If sufficient water is provide (500-700 mm) BATEM 306 and BATEM 317 lines can be grown, otherwise, the other two (BATEM 207 and BATEM 223) can be suitable to grow in the regional conditions.

The objective of this study was to determine the adaptation abilities and quality parameters of selected advanced soybean breeding lines at the double cropped growing conditions. 20 advanced Soybean [Glycine max (L.) Merr] breeding lines (F7) and four soybean varieties having maturity group III and IV (ARISOY, ATAEM-7, BRAVO and NOVA) were used. The differences between the lines and varieties were significant for the grain yield. The mean grain yield of breeding lines and varieties ranged from 2460 to 3488 kg ha-1 and from 2933 to 3440 kg ha-1 , respectively. Also KA-07-05-13 advanced soybean line had the highest grain yield in terms of two years' average. The highest plant height was obtained from KA-07-08-15 (82.2 cm) and the lowest pod height from KA-07-08-15 (12.2 cm) and BDNA-19 (12.1 cm) lines. Significant differences were determined for pod number per plant among the 24 soybean genotypes. The pod number per plant was the higher in BDNA-12 and BDNA-13 lines than the varieties. In this research, the number of day for flowering varied between 33.0-42.1 days and the number of days for maturating ranged from 102.4 to 113.6 days. The earliest flowering time was detected from KA-07-08-14 line and the earliest maturating time was observed from BDNE-14 line. In a two-year average, 100-seed weight ranged between 14.2-20.8 g in breeding lines. The highest 100-seed weight was obtained from KA-07-03-5 (20.8 g) and KA-07-03-9 lines (20.1 g). While the highest oil percentage was obtained from ARISOY, the highest and statistically same oil percentage was recorded from KA-07-05-9 (21,6%), KA-07-08-12 (21,2%) and KA-07-05-5 (21,2%). The average protein content of soybean lines and cultivars varied from 41.6% to 49.3%. The higher protein percentage value was obtained from the BDAF-4 (49.3%) breeding line.

No abstract

Bu çalışmada, farklı biçim zamanlarının yeşil ve mor fesleğen (Ocimum basilicum L.) tiplerinde bazı verim ve kalite özelliklerine etkisini belirlemek amaçlanmıştır. Denemeler Ege Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü'nün Bornova/İzmir'de bulunan deneme tarlasında 2013 ve 2014 yılları yetiştirme dönemlerinde iki yıl süreyle yürütülmüştür. Araştırmada, her iki fesleğen tipinde de ilk hasat, bitkilerin tarlaya şaşırtılmasından 40 gün sonra yapılmıştır ve daha sonra 15 günlük aralarla toplam altı hasat gerçekleştirilmiştir. Çalışmada bitki boyu (cm), yeşil herba verimi (kg da -1 ), drog herba verimi (kg da -1 ), drog yaprak verimi (kg da -1 ), uçucu yağ oranı (%) ve uçucu yağ verimi (l da -1 ) özellikleri incelenmiştir. Tüm özellikler bakımından elde edilen değerler için iki yıl üzerinden birleştirilmiş varyans analizleri yapılmıştır. Varyans analizi sonuçları tüm özellikler bakımından hem populasyon hem de biçim zamanı ortalamaları arasında önemli farklılıkların bulunduğunu göstermiştir. Tüm özelliklere ilişkin populasyon x biçim zamanı interaksiyonları önemli bulunurken populasyon x biçim zamanı x yıl interaksiyonları ise önemsiz olmuştur.

The present research was undertaken to evaluate of soybean hybrids environmental interaction and adaptability on Mediterranean region conditions. Seven advanced (F7) soybean cross breeding lines (KB-67, KS-39, KS-14, KS-12, KS-11, KS-10, KS-2) selected from the Kunitz x SS-201 and Kunitz x Bert crosses populations based on earliness and yield characteristics in the preliminary trials and three soybean varieties (Bravo, Nova and Arisoy) were tested in the trial in four replications in 2017 and 2018 according to the randomized blocks trial design. The analysis of variance revealed significant variations for all characters. According to research findings the yield of lines and varieties 2017 and 2018 varied from 1008.38-1567.13 kg ha-1 and 1018.94-1367.00 kg ha-1 respectively and KS-39 advanced soybean line had the highest grain yield in terms of two years’ average. The highest plant height (95.55 cm) was obtained from KS 11 and the lowest plant height (78.80 cm) from BRAVO variety. According to the two-year average data, KB-67 (129.62 pods per plant) and KS-39 (114.70 pods per plant) lines were the genotypes with the highest number of pods in the plant. The number of flowering days varied between 32.50 days and 36.75 days according to the two-year averages, and the KS-12 genotype was the earliest flowering genotype. The lines KS-10 (103.38) and KS-12 (103.50) came to the fore as the genotypes with the earliest maturation days. Among the lines tested in the experiment, KS-11 in terms of plant height, KS-14 in terms of first pod height, KS-14 in terms of 100-seed weight, and KS-39 in terms of the number of seeds per pod were the lines that showed the best performance.
