    Biber Genotiplerinde Peroksidaz ve Katalaz İçeriklerinin Phytophthora capsici’ye Dayanıklılık Üzerine Etkileri
    (2018) Karipçin, Muhemet Zeki; Durak, Emre Demirer
    Yerel biber genotiplerinde Phytophthora capsici’ye dayanıklılık amacıyla yürütülen bu çalışmada, 60 adetbiber genotipi kullanılmıştır. Araştırmada; kontrol olarak P. capsici’ye dayanıklı CM 334 (Criollos de Morelos334) genotipi seçilmiş, peroksidaz ve katalaz enzim içerikleri araştırılan tüm materyallere iki inokulasyonuygulanmıştır. İlk inokulasyon sonucunda CM 334 no’lu genotip ve 3 (P1), 13 (Urfa), 25 (UKST), 38 (Uİ), 48(UKDT) ve 57 (ANKSB) no’lu yerli genotipler ölmemiştir. İkinci inokulasyon sonucunda ise sadece CM 334 no’lu genotiphayatta kalarak sürgün oluşumuna devam etmiştir. Her iki inokulasyonda da kısmi veya tam dayanıklılık gösterengenotiplerin enzim içeriklerinin de yüksek seviyelerde olduğu, özellikle peroksidaz enzim içeriğinin belirgin bir şekildeayırıcı olduğu sonucuna varılmıştır. İlk inokulasyonda dayanıklılık gösteren tüm genotiplerin peroksidaz içeriği yüksekolarak belirlenirken, katalaz içeriği dayanıklı ve hassas çeşitlerde çok belirgin olarak ortaya çıkmamıştır. Ayrıca, P.capsici’ye dayanıklılığın gelişmenin ilk evrelerinden daha çok, bitki gelişiminin son evrelerinde ortaya çıktığı belirlenmiştir.Çalışma sonucunda, ilk inokulasyonda dahi kısmi dayanıklılık gösteren materyallerin ıslah materyalleri olabileceği vemelezleme programlarına dâhil edilebileceği tespit edilmiştir.

    Determination of heterosis and heterobeltiosis values of salt-tolerant summer squash (cucurbita pepo l.) genotypes and genetic relationships of parental genomes
    (Applied Ecology and Environmental Research, 2017-08-01) Karipçin, Muhemet Zeki; İnal, Behcet
    This study was carried out to determine the heterosis and heterobeltiosis values in F1 hybrids which are obtained through hybridization of salt-tolerant genotypes in summer squash (Cucurbita pepo L.). The materials used were the promising hybrid combinations and their parents, which are previously reported among the salt-tolerant genotypes by detecting the influence of parents on heterosis and heterobeltiosis values in advanced hybridization studies. Eight domestic summer squash genotypes (Tutluca 1, Tutluca 2, Halfeti 1, Halfeti 2, Bozova Mrkz, Yaslıca, Konak and Şanlıurfa Mrkz), were chosen from salt-tolerant genotypes and 28 F1 hybrids obtained through hybridization of these genotypes. The heterotic influences were remarkably important, and it was possible to get promising hybrids in terms of examined traits. Parents were evaluated for plant length (cm), stem diameter (mm), plant width-spread (cm), number of leaves (number), 50% female flowering time (day), yield (kg), parental and hybrid heterosis and heterobeltiosis values (%), and parental contribution to heterosis and heterobeltiosis of F1 hybrids. The highest heterotic effect was determined in the summer squash yield traits. In the yield, a maximum of 32.67% heterosis and 24.36% heterobeltiosis values were obtained. Additionally, genetic relationships of parental genotypes based on chloroplast DNA sequence analysis were compatible with results of heterosis and heterobeltiosis.

    Statistical Evaulation of Watermelon Genotypes Exhibiting Different Features Under Stress Conditions. Fresenius Environmental Bulletin
    (Fresenius Environmental Bulletin, 2018-02-01) Karipçin, Muhemet Zeki
    reflecting phenotypic differences and dissimilar groups. Thus, in addition to applying a standard statistical model using different watermelon genotypes under drought stress, a new formula was also used. The present study also suggests that according to the groupings in the statistical evaluation, the genotypes in the top groups did not yield positive results; thus, the parcel data may change according to the evaluation criteria. The use of a new evaluation model comprising comparative changes in these respective studies is more accurate. In the present study, the data for TSS (total soluble solids), average fruit weight and total yield values were evaluated using both methods of analysis. In conclusion, as a result of the standard statistical analysis, genotype nos. 325 and 26 have the best group, while the evaluation according to comparative variation criteria demonstrated that genotype nos. 24, 25, 27 and 218 have the best group. Thus, the most reliable evaluation method was to use the new evaluation model comprising comparative variations.
