Intenzivni uvjeti proizvodnje, selekcija usmjerena na povećanje postotka mišićnoga tkiva u polovicama te zahtjevi potrošača doveli su do smanjivanja udjela intramuskularne masti u trupovima svinja. ...Intramuskularna mast je čimbenik koji utječe na okus, sočnost i mekoću mesa. Porodica FABP proteina dovodi do razlike u sadržaju intramuskularne masti kod različitih pasmina svinja. FABP3 i LEPR geni su kandidatni geni za svojstvo intramuskularne masti, a njihovi polimorfizmi objašnjavaju varijabilnosti koje se javljaju kod različitih pasmina svinja. Cilj je ovoga rada prikazati utjecaj gena na različiti sadržaj intramuskularne masti u trupovima svinja s obzirom na njihov genotip.
Seventeen hybrid maize genotypes were evaluated at four locations (Yenişehir-
Marmora Region; Bornova-Aegean Region; Ceyhan-Mediterranean Region; Seyhan-
Mediterranean Region) in 2005 and 2006 ...cropping seasons under irrigated conditions in
Turkey. The analysis of variance for grain yield of the 17 hybrid genotypes tested in
eight environments showed mean squares of environments, genotypes and GEI
(genotype x environment interaction) were highly significant and accounted for 62.1%,
12.5% and 25.4% of treatment combination sum of squares, respectively. To determine
the effects of GEI on yields, the data were subjected to additive main effects and
multiplicative interaction (AMMI) and the GGE biplot analysis.
Although mean grain yield of the check cultivar G12 was higher than those of
experimental hybrids, difference between G12 and G16, which is the most stable
genotype according to AMMI and GGE biplot, was insignificant. It is understood that
the experimental hybrid maize G16 can be proposed in reliably for growing by the
farmers. Also, it was detected that only the test environment E3 (Ceyhan location) may
be sufficient for deciding about which experimental hybrids can be recommended,
instead of four test locations (Ceyhan, Seyhan, Bornova and Yenişehir) in this study. In
addition, it is concluded that there is no difference between the AMMI and GGE biplot
analysis in evaluation of experimental maize hybrids and test environments in this
research and that both methods can be used successfully in determining suitable
locations for maize hybrids in the environments under Mediterranean climate conditions.

Bu çalışmada Yozgat ilinin kaz yetiştiriciliğindeki mevcut durumu ve üreticilerin bu türden yararlanma düzeylerinin belirlenmesi amaçlanmıştır. Bu amaçla, il genelinde yaygın üretim yapılan ...yörelerdeki 200 üretici ile yüz yüze görüşme yapılarak bir anket gerçekleştirilmiştir. İlde kaz yetiştiriciliği genellikle bir tüketim alışkanlığı olarak kendi et ihtiyaçlarını karşılama amacıyla kazların gündüz serbest şekilde gezindiği akşamları ise kapalı bir alanda barındırıldığı üretim sistemi şeklinde yapılmaktadır. Diğer hayvancılık faaliyetlerine ek olarak yapılan kaz yetiştiriciliğinde kış döneminde damızlık olarak 2-25 kazın elde tutulduğu, kazlardan ortalama 11 adet yumurta alındığı, bu yumurtaların tamamının doğal kuluçkada değerlendirildiği ve ortalama 8 adet palaz üretildiği sonucuna ulaşılmıştır. Elde edilen palazlardan yeterli dişi ve erkek damızlığa ayrıldıktan sonra geri kalanlar beslenerek ortalama 8 aylık yaşta kesilmektedir. Bu çalışmanın bulguları anket verilerine dayandığından, yöredeki kazların üretici koşullarındaki verim düzeylerinin yanı sıra, uygun koşullar altında gerçek verim seviyelerinin de ortaya konulması için araştırma çalışmalarına ihtiyaç duyulmaktadır. Son yıllarda canlı kaz satışlarında artış olması, yörede daha yüksek verimli kaz varyeteleri ile çalışılmasının uygun olacağını göstermektedir
‘Žilavka’ has been grown in Bosnia and Herzegovina since the XIVth century and is exploited for wine production. Although not sufficiently studied, this grapevine cultivar has high economic potential ...for the country. Five survey missions resulted in the collection of eighty ‘Žilavka’ accessions that varied in terms of names and characteristics. Because of the unknown origin of the cultivar, these accessions were analyzed with microsatellites markers in order to obtain a standard ‘Žilavka’ genotype. AFLP markers were used to investigate the genetic basis of variability within the cultivar. ‘Žilavka’ grapevines were screened on 14 microsatellite loci, thus revealing 4 different genotypes arising from mutations observed at 10 polymorphic loci. AFLP analysis of 52 ‘Žilavka’ accessions revealed 35 different genotypes, with an average polymorphism of 57 %. Cluster analysis showed no grouping of different Žilavka accessions according to their names, characteristics or collection locations. The standard ‘Žilavka’ genotype was further compared to 211 cultivars from Slovenia (49), Austria/Germany (20), France (13), Portugal (27), Croatia (19), Greece (32), Spain (21) and Italy (30) in order to assess their genetic relationships. In pairwise comparisons, the highest genetic similarity was found with Slovenian cultivars ‘Glera’ and ‘Briška Glera’ (64 %) and the highest genetic dissimilarity (100 %) with two Italian cultivars, ‘Nebbiolo Lampia’ and ‘Vespolina’. Inventory, collection and genetic characterization of ‘Žilavka’ accessions are important steps towards cultivar standardization, identification of parental cultivars and investigation of cultivar origin, required for its sustainable use.
‘Žilavka’ je pomembna vinska sorta z območja Bosne in Hercegovine kjer jo gojijo že od XIV stoletja. V preteklosti ni bila dovolj proučevana vendar ima velik ekonomski potencial za omenjeno območje. Akcesije žilavke (80), ki imajo različna imena in se razlikujejo po nekaterih osnovnih karakteristikah so bile nabrane na različnih področjih Bosne in Hercegovine. Za pridobitev standardnega genotipa žilavke smo uporabili mikrosatelitne markerje in z analizo 14 lokusov odkrili mutacije na 10 lokusih in določili 4 različne genotipe. Vse akcesije (52) katerim smo na osnovi mikrosatelitov določili standardni genotip smo nadalje analizirali z AFLP markerji in tako določili 35 različnih genotipov. Povprečni polimorfizem pri AFLP analizi je bil 57 %. S klastrsko analizo nismo odkrili skupin povezanih z različnimi karakteristikami, poimenovanjem ali izvorom akcesij žilavke. Standardni genotip žilavke smo nadalje primerjali z genotipi 211 kultivarjev iz Slovenije (49), Avstrije/Nemčije (20), Francije (13), Portugalske (27), Hrvaške (19), Grčije (32), Španije (21) in Italije (30), da bi ugotovili kakšna je sorodnost z njimi. V analizi primerjave parov smo ugotovili, da je žilavka najbolj sorodna (64 %) s slovenskima kultivarjema ‘Glera’ in ‘Briška Glera’ ter najbolj genetsko oddaljena od italijanskih kultivarjev ‘Nebbiolo Lampia’ in ‘Vespolina’. Zbiranje, vrednotenje in genetska karakterizacija akcesij žilavke je pomembna za standardizacijo kultivarjev, analizo starševstva in izvora sorte.
Theobroma cacao L. is a commercial tree derivate chocolate, which is originally from tropical regions of Central and South America. Currently, cacao is distributed throughout warmer climates in South ...and Central America, Africa, and South East Asia including Indonesia. Sulawesi Island of Indonesia has contributed significantly on cacao bean production over more than a decade. Intensive and extensive developments of this plant have been progressively done. One of these steps is the introduction of various new superior cultivars/clones. In current status, due to introduction of numerous cultivars and clones, it raises the variability of cacao trees on the field and derivate products from it. However, screening based on genotype and phenotype properties is urgently elucidated. In this paper, we report the variation of distinguishable pot morphology and genetic variation based on SSR marker from several clones, collected from Central Sulawesi farms. Among the samples could be characterized based on pot performance including; shape, size, bean properties, etc. Genotyping was done by using SSR marker. The outcome clearly shows that the polymorphism among the samples indicates high evolution rate on cacao trees over Sulawesi Island.
