Öğe Effect of fertilizer rate on the growth, yield and fruit characteristics of dried apricot (cv. Hacihaliloglu)(Asian Network for Scientific Information, 2007) Asma B.M.; Colak S.; Akca Y.; Genc C.Various Nitrogen (N), Phosphor (P) and Potassium (K) fertilization were investigated in apricot trees (cv. Hacihaliloglu) grown in Malatya, Turkey. High N application increased vegetative growth, yield and average fruit weight, but reduced total soluble solid content. K fertilization did not affect vegetative growth but resulted increase in total soluble solids and yield. High phosphor treatments showed yield increase while slowed vegetative growth. Based on yield, vegetative growth and fruit characteristics, the most effective fertilization rate for apricot (cv. Hacihaliloglu) was found to be 96-64-256 kg ha -1 NPK. © 2007 Asian Network for Scientific Information.Öğe Genetic relatedness in prunus genus revealed by inter-simple sequence repeat markers(American Society for Horticultural Science, 2009) Yilmaz K.U.; Ercişli S.; Asma B.M.; Do?an Y.; Kafkas S.Inter-simple sequence repeat (ISSR) markers were used to study the genetic diversity and phylogenetic relationships among 16 genotypes from subgenus Prunus (six genotypes from section Prunophora, seven genotypes from section Armeniaca and two plumcot genotypes, and one genotype from subgenus Cerasus) in Prunus genus. From the polymerase chain reaction amplifications with 20 ISSR primers showing polymorphism among subgenera and sections, 180 polymorphic ISSR bands were detected and polymorphism ratio ranged from 57% to 100%. Based on the unweighted pair group method with arithmetic mean (UPGMA) analysis and principal coordinate analysis (PCoA) using the Jaccard coefficient, a dendrogram and three-dimensional plot were constructed including genotypes in Prunus genus. Two main groups formed in the dendrogram; one of them (Cluster I) included Cerasus, whereas Cluster II included Prunus. Cluster II also divided into three subgroups, including sections Prunophora, Armeniaca, and plumcot. Both UPGMA and the PCoA demonstrated that Armeniaca genotypes had lower genetic variation and plumcot genotypes are closer to the plums than the apricots. The ISSR-based phylogeny was generally consistent with Prunus taxonomy based on molecular evidence, suggesting the applicability of ISSR analysis for genotypic and phylogenetic studies in Prunus genus.Öğe Pomological and phenological characterization of promising walnut (Juglans regia L.) genotypes from Malatya, Turkey(Wydawnictwo Akad Rolniczej W Lublinie, 2012) Asma B.M.Turkey has significant walnut (Juglans regia L.) plantations most of which are seedling-grown trees. Eastern Anatolia region of Turkey has rich phenotypic diversity. In this study, walnut genotypes of the region were evaluated and considerable genetic variation in pomological and phenological characteristics was found in walnut genotypes which were of seedling origin. The study region was about 12 000 km2 are between 35°54?-39°03? N latitude and 38°45?-39°08? E longitude. It is estimated that the region has 162 800 walnut trees. During our survey more than 3000 walnut genotypes were observed for several horticultural characteristics. Selections studied were carried out among these populations. Based on several horticultural characteristics, 158 genotypes were selected. Here, we report the several characteristics of 16 superior walnut genotypes of these 158 selections with promising yield and fruit characteristics. Among our selections we observed the ranges of 65-100% for terminal fruitfulness, 38-67 % for lateral fruitfulness, 1.98-3.15 fruits for terminal shoots, 1.36-2.25 fruits for lateral shoots, 12.6-17.5 g nut weight, 6.9-9.1 g kernel weight, 47.3-60.8% kernel ratio and 0.95-17.5 mm shell thickness. The most promising genotypes were 94 Mws 30, 95 Mws 78 and 97 Mws 103, and these selections will be used for further breeding efforts.
