The research was carried out to determine the effects of different mixture ratios and cutting times on dry-matter yield and silage quality of mixtures of bersem clover (Trifolium alexandrinum L.) with Italian ryegrass (Lolium multiflorum Lam.) in Adana province, Turkey. The experiment was laid out in split plot design with four replications during the years of 2011-2013. The mixture-ratios ( 80% BC + 20% IR, 60% BC + % 40 IR, 40% BC+ % 60 IR, 20% BC + 80 % IR, pure berseem clover (BC) and Italian ryegrass (IR) ) were main plots, and harvest times (beginning of the flowering, mid flowering and full flowering of BC) were sub-plots. From the result of the study, it was concluded that the mixture of 60 % BC + 40 % IR harvested at full flowering of BC was superior in terms of dry matter yield and silage quality.
Chickpea (Cicer arietinum L.) is one of the important legumes widely grown for dietary proteins in semi-arid Mediterranean climatic conditions. The main goal of any breeding programs in the world is to produce high yield and better quality genotypes for farmers and commercial growers to be released as cultivars. Present research has been conducted to select more desirable characteristics that may contribute to the improvement of drought tolerant chickpea. Thirty-two chickpea genotypes along with two control varieties were evaluated in winter and late sowing conditions in 2015 and 2016, in randomized complete block design with three replications. Phenotypic coefficients of variation were found to be higher than genotypic coefficients of variation for all the traits. The highest heritability along with high genetic advance was found for hundred seed weight followed by podding day, plant height, flowering day and first pod height in normal and stress conditions. These traits can be improved by giving special attention during selection.
Urfa ekolojik koşullarında bazı nohut hat ve çeşitlerinin tarımsal özelliklerinin belirlenmesi amacıyla 2014-2015 yıllarında yürütülen bu çalışma GAP Tarımsal Araştırma Enstitüsüne ait deneme arazilerinde yürütülmüştür. 20 tescilli nohut genotipi ve 3 kontrol çeşidi kullanılarak yürütülen çalışma tesadüf blokları deneme desenine göre üç tekrarlamalı olarak kurulmuştur. Araştırmada nohut bitkisinde %50 çıkış sağlandıktan sonra çiçeklenmeye kadar geçen gün sayısı, bakla bağlama, çıkış sağlandıktan sonra kadar geçen gün sayısı ve vejetasyon süresi gibi fenolojik özellikler ile bitki boyu, ilk bakla yüksekliği, hasat olgunluğu, yüz tane ağırlığı, dekara verim gibi ağronomik özellikler incelenmiştir. Çalışma süresince nohut çeşitlerinin iklim koşullarına bağlı olarak Ascochyta solgunluk hastalığı kontrolleri de yapılmıştır. Araştırmada Urfa lokasyonunda tane verimi bakımından en yüksek değeri 202.32 kg/da ile Sezen Bey çeşidinden, en düşük tane verimini ise 117.58 kg/da ile Seçkin çeşidinden elde edilmiştir. Her iki yetiştirme sezonunda ortalama Protein analiz değerleri ise en yüksek Seçkin çeşidinden % 26.45, en düşük değer ise İnci-K çeşidinden % 21.66 değerleri elde edilmiştir.
In order to gain insight into the complex molecular networks driving legume adaptation caused by climate change, it is necessary to deeply characterize the existing germplasm in response to the environmental constraint predicted to worsen in the near future: drought. In this study, we propose to perform a three-year deep agronomic characterization of local genotypes of selected legumes in abiotic stressing conditions through controlled and field experiments conducted in several countries of the Mediterranean basin (Italy, Spain, Algeria, Tunisia, Turkey, Lebanon, and Croatia). These phenotypic analyses will be integrated with a multi-omic approach aiming at identifying the key players involved in the modulation of the analyzed traits that includes the analysis of the plant methylome, transcriptome, and proteome. Following this approach, we propose to deliver epigenomic markers linked with rapid adaptation mechanisms in response to drought. Besides, new genetic variability by breeding could be created in stressing conditions and produce the basis for the obtainment of more productive cultivars in worsening environments. The epigenetic marks identified in "omic" activities will be validated in molecular marker-assisted selection in F2-F4 populations. Finally, specific rhizobia strains for the best evaluated genotypes will be identified in order to enhance symbiotic nitrogen fixation in drought stress conditions with selected cultivars. -M.; visualization, F.M. and F.P.-M.
