Five hybrid lines of forage peas (No. 14, No. 6, No. 12A, No. 13 and No. 9) and the Mir variety (... more Five hybrid lines of forage peas (No. 14, No. 6, No. 12A, No. 13 and No. 9) and the Mir variety (standard) were studied in terms of ripeness and yield of grain and green mass. The study was performed in the experimental field of Institute of Forage Crops - Pleven, Bulgaria (2016- 2018). The occurrence of the phenological stages beginning of flowering, full flowering, and technical maturity (days) was monitored. At the full bottom pods stage the green mass yield (kg/da), and at the technical maturity stage the grain yield (kg/da) were recorded. The line No. 14 (vegetation period 218 days) was found to develop faster than other lines. Plants from this line enter the flowering stage much earlier than the Mir variety and reach technological maturity at the earliest. At ripeness, the lines are arranged: line No. 14 (218 days), line No. 12А (222 days), Mir variety (224 days), line No. 6 (225 days) and line No. 13 (233 days). Lines No. 13 and PL managed in the most unfavorable environment to fully manifest their biological potential and to accumulate more green mass (2007 and 2059 kg/da, respectively). In terms of grain yield, line No. 14 exceeds the standard by 35.42% on average over the period. Grain yield after it, lines No. 6 and 12А are ranked, with an excess of 21.53% and 20.83% respectively. For breeding purposes line No. 14 may be used in terms of ripeness, lines No. 14, 2А and 6 in terms of grain yield. The study is a contribution to the selection for the creation of new genotypes of forage peas with pronounced ripeness, increased ecological stability of both, green mass and grains.

However, rapeseed could not be produced large areas in Turkey like other countries although it has more suitable conditions to grow easily. On the other hand, rapeseed is very suitable for fraying and biodesel. The study was conducted to determine the fatty acid composition of some rapeseed variety in Diyarbakır Province which is outh East Anatolian Region conditions in 2007-2008 and 2008-2009 growing seasons.. Five rapeseed variety (Catalina, Elvis, Jura, Licord and Orkan) were used in the study. Based on study results, , the highest palmitic acid obtained from Jura variety with 6,87 % and the lowest was obtained from Orkan variety with 6,29 %. The highest stearic acid was obtained in Catalina variety with 2,70 % and the lowest was obtained in Licord variety with 2,38 %. The highest Oleic acid was obtained in Elvis variety with 58,36 % and the lowest was obtained from Jura variety with 51,45 %. The highest Linoleic acid was obtained in Orkan variety with 21,21 % and the lowest was obtained in Licord variety with 19,32 %. The highest Linolenic acid was obtained in Licord variety with 10,33 % and the lowest was obtained in Catalina variety with 8,03 %. The highest Arachidic acid was obtained in Catalina variety with 0,33 % and the lowest was obtained from Elvis variety with 0,11 %. According to the two years average results from this study indicated that Elvis and Catalina variety in respect to fatty acid composition can be suitable in South East Anatolian Region

The research covered the changes on inputs and product prices at real base in sunflower and its cost of production in Trakya Region. Total income was found as 1178 US$/ha, total production cost 1138 US$/ha, gross profit 444 US$/ha and net profit was calculated as 39 US$/ha in the research. Although the domestic production cost per MT sunflower seed was calculated as 650.29 US$, the import cost was found as 487.5 US$. Therefore, the import of sunflower seed seems attractive for sunflower oil industry in Turkey. Although inputs such as fertilizer 267%, fuel 105%, seed 14% exhibited in sunflower production, sunflower seed decreased 4.12% in 1999-2008. Research results indicated that subsidizing policy was not efficient to increase oil seed production and oil crops. Based on this situation, the vegetable oil deficit expects to continue in future in Turkey.

In addition to be the most preferable vegetable oil in the Eastern Europe, Balkans and Blacksea region, sunflower is the main crops in the rotation system in the agricultural production as well as the most planted oil crops in these areas. Both world sunflower planted areas (21.000 ha in 2007 to 26.000 ha in 2019) and also seed production (26.000 MT in 2007 to 51.000 MT in 2019) have raised in last ten years but Blacksea region contributed mainly for these increases. In the region, while sunflower production has tripled from 11800 MT (2007) to 35.000 MT (2019), sunflower planted areas has raised 60% more from 2007 to 2019 (10.000 to 16.000 ha) in last 12 years. The rate of region in sunflower production has increased from 45 to 68%, acreages from 49 to 64% in this period. Furthermore, the region plays key role and also dominated sunflower world trade as well as other oilseeds such as canola and soybean. As a spring crop, sunflower influence eventually from climatic conditions such as temperature, soil humidity, etc. in some critical stages which are determining seed and oil yield especially bud formation and the grain filling period. Biotic and abiotic stresses coincide in these two stages lead extremely reduce seed yield regularly in sunflower production areas in due to unregularly rainfalls and higher temperatures in spring and early summer seasons in Blacksea region which sunflower grows mostly in dryland. Therefore, it need to well understand these reducing factors and sunflower responses and mechanisms then it need to find accurate management solutions to cope with these factors efficiently such as early planting time and increasing plant density for obtaining better yields. Besides, biotic stresses mostly diseases such as downy mildew, Phomopsis, Sclerotinia, Verticilium wilt, Macrophomina and also broomrape parasite, weeds are the main factors reducing sunflower yield in the region. While there is only genetic resistance possible for disease control mentioned above ones, effective control of broomrape and weeds are possible Clearfield system with post emergence Imidazolinone (IMI) herbicide plus resistant varieties as well as sulfonyl Urea (SU) herbicide and resistant hybrids. Furthermore, combining these herbicide resistances together with new races of broomrape races and downy mildew and other diseases will lead higher yield results in sunflower production in the region in addition to other agronomical solutions.

Seven varieties of white lupine were used. Analysis of variance showed a well-proven influence of genotype and environment factors and the interaction between them in terms of plant height, number of pods, number of seeds and seeds weight. For plant height, number of seeds and seeds weight, the influence of the environment was stronger than that of the other two factors. The seeds weight strongly correlated with the Anicchiarico Wi indices (r = 0.87), bi (r = 0.634), ai (r = 0.633) and T (r = 0.559) and negative correlated with the Lin and Binns (r = -0.977) parameter. Ecological stability parameters for plant height showed the most stable and high-growing PI533704 variety; for the number of pods, number of seeds and seeds weight Zuter variety, respectively. Zuter variety was found close to the ideal type combining high productivity with ecological stability. Lucky801, for most signs, was environmentally unstable but highly productive and is therefore suitable as a parent component in breeding programs for obtaining high yield varieties.

The varieties are characterised by low general adaptive ability and average specific adaptive ability on the investigated signs. With the highest general adaptive ability by fresh leaf weight is distinguished BGE000643, by number of nodules per plant BGE004222 and BGE001383, and by plant height - BGE001847 and BGE000637, respectively. By the complex indicator selection value of the genotype, taking into account the general adaptive ability and stability, the signs fresh leaf weight and fresh stem weight the best was found BGE001383 variety. According to the number of nodules per plant and the indicators of adaptability and stability, the interest represents the variety BGE004222. Based on the aggregate assessment of the varieties, which is based on the average height of the plant and the parameters of adaptability, the most valuable were the varieties BGE001847 and BGE001076. A positive correlation was established between fresh leaf weight and: the specific adaptive ability (r = 0.568), the general adaptive ability (r = 0.099) and the indicator of the stability level of the variety (r = 0.544); and between the number of nodules with the coefficient of linear regression (r = 0.115) and with homeostaticity (r = 0.116).

Herbicide Resistance Breeding in Sunflower, Current Situation and Future Directions

Therefore, breeders should develop new higher yielding and dry tolerant cultivars and also should find new production techniques to increase production with reducing of effects of environmental factors influenced seed yield. Weeds and broomrape (Orobanche cumana Wallr.) exist among the most limiting factors for sunflower production in especially in Eastern Europe and Black Sea Region. Clearfield Technology which using post emergence Imidazolinone (IMI) herbicides with IMI resistant cultivars presents efficient results both control broomrape and major broadleaf weeds in sunflower production. Furthermore, Sulfonyl Urea (SU) herbicide as post application like IMI is also another method to control weeds efficiently and it is preferred being cheaper than IMI....

ve Karadeniz Bölgesi'nde en çok yetiştirilen, en çok tüketilen ve üretilen yağlı tohumdur. Bölgede aynı zamanda dünya ayçiçeği üretiminin de %60'dan fazlasını üretilmektedir. Orijini Amerika da olsa, ayçiçeği Rus araştırmacılar tarafından yağ bitkisi olarak geliştirilmiş ve ilk olarak bu bölgedeki yetiştiriciler tarafından üretilmiştir. Ayçiçeği, kumlu, çorak tuzlu ve kayalık topraklara kadar yetişen yabani akrabalarından gelen genetik çeşitliliği daha fazla koruduğu için, çok kuru ve normal mevsimsel yağışla birçok değişik bölgelerde yetişebilir (Skoric, 2012; Kaya ve ark., 2012; 2020).
Ayçiçeği, ülkemizde ve dünyada yazlık ve genelde sulanmadan
yetiştirildiğinden kuraklık, aşırı sıcaklık vb çevresel faktörlerden en fazla
etkilenen bitkilerden biridir. Ülkemizde ilkbaharda ekilen ayçiçeğinin ilk gelişme döneminde ihtiyacı olan su miktarı, kış yağışlarıyla toprakta biriken sudan karşılanmaktadır. Tane verimi için kuraklık açısından en kritik periyot, Haziran-Temmuz ayları olup, bu dönem tabla oluşumundan başlayıp, tane dolumunu da içerisine almaktadır (Kaya ve ark., 2005, 2012; 2020; Skoric, 2012; Sahin ve ark., 2020). Yapılan araştırmalarda ayçiçeğinde bu kritik dönemde kuraklığın 5 haftadan fazla sürmesi durumunda, kuraklığın önemli verim kayıplarına yol açtığı, tozlanmayı durdurduğu ve yağ verimini de etkilediği bildirilmiştir (Hussain ve ark., 2000; Fernandez ve ark, 2009; Skoric 2012).
