Abstract
This research was conducted in order to investigate the genetical structure of a population of six cotton genotypes and their half diallel crosses. In this study, Paum-15, Stoneville-453, Fantom, Nazilli-84S, Delcerro and Giza-45 cotton genotypes were used as parents. This study was carried out at GAP International Agricultural Research and Training Center’s experiment area in 2010-2011. The experimental set up was randomized complete block design with three replications. Data were examined by Jinks-Hayman diallel analysis method. According to the results of Jinks-Hayman diallel analysis additive and dominant gene variance were found significant for the percentage of the first hand harvest trait. Presence of partial dominance in the percentage of the first harvest was occurred. Alleles enhancing the trait are dominant. Dominant genes are usually effective in the same direction. The percentage of the first harvest trait management, the frequency of recessive gene alleles is greater than the dominant allele gene frequency and variance of additive gene is more effective than variance of the dominant gene. The highest heritability for both heritability types was recorded for the percentage of the first harvest (h²n=0.514, h²b =0.915). In improving the trait selection in early generations will be more successful. vered greenhouse of Agrobest Group, in Gaziler Village (Kepez-Antalya) during the winter-summer season of 2014. Three different doses of Symbion-P were used as treatments: suggested dose (D, 300 ml da-1), half of suggested dose (D/2, 150 ml da-1) and two fold of suggested dose (Dx2, 600 ml da-1), and non-inoculated plants (0.0 ml da-1) were put on trial as control group. Symbion-P was applied twice: at transplanting time and 15 days after transplanting via irrigation lines. All plants were transplanted on January 1, 2014 as 2 plants per m2. The experiment was terminated on June 30, 2014 when plants were at the 6th trusses stage. The experimental design was randomized parcel with 4 replicates and parameters related to plant growth (plant height, stem diameter, fresh and dry weights of vegetable part and fruit), yield (first flowering time, total and marketable yield, total fruit number and average fruit weight) and fruit quality (colour, firmness, dry weight, total solube solids, titratable acidity, EC, pH, vitamin C and nitrate content) were determined. The results showed that plant growth, total and marketable yield increased by the application of biofertilizer; yields increased with increasing doses and the application of 600 ml per da (Dx2) was found the most appropriate dose for better yield and quality.
Özet
Bu araştırma, 6 pamuk genotipi ve bunların yarım diallel melezlerinden oluşan popülasyonun ilk el kütlü pamuk oranı özelliğinin genetik yapısını araştırmak amacı ile yürütülmüştür. Çalışmada, Paum-15, Stoneville-453, Fantom, Nazilli-84S, Delcerro ve Giza-45 genotipleri ebeveyn olarak kullanılmıştır. Araştırma GAP Uluslararası Tarımsal Araştırma ve Eğitim Merkezi Müdürlüğü deneme alanlarında 2010 ve 2011 yıllarında yürütülmüştür. Deneme tesadüf blokları deneme desenine göre 3 tekerrürlü olarak yürütülmüştür. Çalışmada verilerin analizi, Jinks-Hayman tipi diallel analiz yöntemleri kullanılarak gerçekleştirilmiştir. Jinks-Hayman diallel analiz yöntemi ile incelenen ilk el kütlü pamuk oranı özelliği üzerine hem eklemeli hem de dominant genlerin etkili olduğu; dominantlığın, eksik dominantlık düzeyinde olduğu; özelliği artırıcı allellerin, dominant olduğu; genlerin genellikle aynı yönde etkili; incelenen ilk el kütlü pamuk oranı özelliğinin yönetiminde resesif allel gen frekansının, dominant allel gen frekansından daha fazla ve eklemeli gen varyansının, dominant gen varyansından daha etkin olduğu; dar ve geniş anlamda kalıtım derecesinin yüksek olduğu (h²d=0.514, h²g=0.915); özelliğin geliştirilebilmesi için erken döl kuşaklarında yapılacak seleksiyonun başarı şansının yüksek olduğu belirlenmiştir.
