This study was carried out to determine direct and indirect effects of some charactrs single leaf area, leaf SPAD value, number of nods, number of sympodial branches, number of monopodial branches, single boll weight, number of bolls) on seed cotton yield. The experiment was carried out with four cotton varieties, two of which okra-leaf (Adana 98, Siokra 1/4) and two of which normal-leaf (Teks and Stoneville 453) cotton (Gossypium hirsutum L) and was conducted the randomized block design with 4 replications. In order to increase seed cotton yield In the studies of breeding program and selection orderly leaf SPAD value, number of sympodial branches, single boll weight, number of monopodial branches and number of bolls charactem determined that must be high. Results showed that in order to increase seed cotton yield in the studies of breeding program and selection the highness of leaf SPAD value, number of sympodial branches, single boll weight, number of monopodial branches and number of bolls charactem should be considered important. © Triveni Enterprises, Lucknow (India).

This study was carried out to determine the effect of nitrogen doses and irrigation levels on fatty acid composition of peanut oils grown in Southeast Anatolia Region. Nitrogen and irrigation levels affected all parameters tested significantly (P<0.01) except for oleic acid which not affected by irrigation levels. There were no regular and certain differences between irrigation and nitrogen levels. So increasing irrigation and nitrogen levels did not increase or decrease in fatty acid content steadily. Palmitic acid varied from 9.86 to 10.31%, stearic acid varied from 4.55 to 5.06%, oleic acid varied from 52.00 to 53.31%, linoleic acid varied from 21.77 to 23.14%, linolenic acid varied from 0.046 to 0.054 %, arasidic acid varied from 1.75 to 2.23%, and behenic acid varied from 2.08 to 2.60 %, respectively. Some of the correlation coefficients among fatty acids were found significant and negative correlation was found between oleic and linoleic acid contents (P<0.01). Source

The objective of this study was to investigate the general combining ability (GCA) of parents and specific combining ability (SCA) of hybrids and also the genetic behavior for studied characteristics in the population obtained by 7×7 half diallel quantitative analysis method involving four MAR (Multi Adversity Resistance) and three commercial cotton (Gossypium hirsutum L.) varieties. The twenty one F1 and seven parents were planted as a randomized complete block design with four replications in 2004. The general combining ability (GCA) variance effects of the parents and the specific combining ability (SCA) variance effects of the hybrids and the gene effects were estimated by using the half diallel analysis method 2, model 1, described by Griffing. In the populations ginning percentage, fiber length, fiber fineness and fiber elongation properties were influenced by additive; seed cotton yield, fiber strength and fiber uniformity ratio were influenced by non-additive gene effects. Significant and positive heterosis values were observed except in fiber uniformity for seed cotton yield, fiber strength, fiber fineness, fiber elongation and ginning percentage respectively. It was determined that 'Sayar 314' for seed cotton yield and fiber length, 'Tamcot CD3H' for fiber uniformity ratio, 'Tamcot Sphinx' for fiber strength, 'Tamcot Luxor' for ginning percentage and fiber elongation, 'Tamcot HQ95' for fiber fineness were the best parent cotton cultivars and also having the best (GCA) general combining abilities. It was also determined that 'Maraş 92' x 'Tamcot HQ95' for fiber fineness, 'Stoneville 453' x 'Tamcot Sphinx' for seed cotton yield, 'Tamcot HQ95' x 'Tamcot Sphinx' for ginning percentage and fiber elongation, 'Maraş 92' x 'Sayar 314' for fiber length, 'Maraş 92' x 'Tamcot HQ95' and 'Tamcot CD3H' x 'Tamcot Sphinx' for fiber strength, 'Sayar 314' x 'Stoneville 453' for fiber uniformity ratio hybrid combinations were the most promising crosses with the highest specific combining ability.

Surveys were made in the main grape growing region (Southeast Anatolia) of Turkey for the occurrence of Grapevine leafroll-associated virus-5 (GLRaV-5). Plant samples with typical leafroll symptoms and mealybugs, Planococcus ficus (Signoret) were used for assessing the occurrence of GLRaV-5 by RT-PCR. A 272 bp band representing GLRaV-5 infection was successfully detected in plants and mealybugs in some vineyards of the Southeast Anatolia region and the virus is the first time reported in Turkish vineyards. © 2009 Blackwell Verlag GmbH.

Vineyards in Turkey were surveyed from July-August of 2006-2007 for the presence of mealybug infestation and the viral agents of leafroll and rugose wood diseases, namely vitiviruses and ampeloviruses, respectively. Plant and insect samples in the main grape-growing regions were collected and processed for nucleic acid isolation. The reverse transcription polymerase chain reaction (RT-PCR) was used to detect the insect-transmitted Grapevine virus A (GVA) and B (GVB) (Vitivirus) and Grapevine leafroll-associated virus-1 (GLRaV-1) and 3 (GLRaV-3) (Ampelovirus). All viruses except GVB were detected in the samples. Planococcus ficus (Signoret) is the only mealybug species found to be widespread in the sampled areas. This is the first epidemiological study of these viruses and their potential vector in Turkey. © 2012 The Canadian Phytopathological Society. Source
