Tz. Kikindonov, S. Enchev, K. Slanev
Abstract. The influence of the in-row sowing rate for different varieties of Sudan grass and Sorghum x Sudan grass hybrids on the green mass productiveness in brooming stage was studied in 2010–2011. In significantly differing agro-climatic conditions of the two years the denser sowings form higher yield of green and dry mass, and the rainfalls distribution has a significant importance for the more favorable yield structure. The tested varieties and hybrids have high productive potential for stable yields of green mass in conditions of extreme deviations from the agro-climatic norms.

Abstract. The studies have been carried out through demonstrative experiments by the first in the country private Seedsman’s house “Sadovo”. Presented are the results from the studies on the productivity and some qualitative indices of the varieties of common soft wheat over a period of 6 years. The subject of the study are the varieties Pobeda, Bononia, Sadovska belia and Diamant which take about 1/3 of the total area of wheat in the country. Parallel with these data, the data on the new generation of varieties Sapfir, Trakiyka, Lazur and Zebrets, and the new genotypes – Apolon, Bezmer, Sezam and Bendida are presented as well. The Pobeda variety has been a national standard of the high-quality, strong wheat – improvers of flour (group A) for 25 years, and the rest three varieties present a new achievement in selection of highly productive, intensive and quality varieties which are well accepted in production of bread grain in Bulgaria. The Diamant variety is distinguished for its high quality.

Abstract. Five winter feed barley varieties were tested at the experimental field of the Institute of Agriculture – Karnobat over a six-year period to assess their yield potential and stability. Varieties Bozhin and Iz Bori are new varieties and Vesletc, Izgrev and Aheloj 2 are widely grown feed barley varieties in Bulgaria. Stability parameters were estimated by the model of Lin and Binns (1988) and GGE biplot methodology was used for graphical display of yield data. According to the results, genotype x environment interactions for grain yield was highly significant indicating genetic variability between genotypes by changing enviroment. Average grain yield of varieties in six-year trail ranged from 5.13 t/ha (Vesletc) to 5.78 t/ha (Bozhin). High yield combined with high stability was demonstrated by new varieties Bozhin end Iz Bori.

I. Nikolova, N. Georgieva

Abstract. During the period 2006-2009 in the experimental field of IFC-Pleven a field trial was conducted with 8 alfalfa varieties included in the Official variety list of Bulgaria (2005): Europe (France), Prista 2 (Obraztsov chiflik, Ruse), Prista 3 (Obraztsov chiflik, Ruse), Prista 4 (Obraztsov chiflik, Ruse), Obnova 10 (IFC, Pleven), Pleven 6 (IFC, Pleven), Dara (IFC, Pleven), Multifoliate (Obraztsov chiflik, Ruse). Most pronounced was the nodulation in varieties Europe, Obnova 10 and Multifoliate (average for the period 71.2, 66.8 and 65.1 pcs. of nodules/10 roots). Damaged nodules by larva of species of genus Sitona increased from spring to autumn regrowth in different years from 2.86% to 21.35%. As tolerant varieties to the damages of species of genus Sitona was manifested Obnova 10 and Multifoliate – the percentage of damaged nodules was average 6.83 and 7.93, the density of fretted fosses was 13.8 and 13.9 pcs. of fosses/10 roots, the percentage of damaged plants was 31.3 and 32.2%. The established varieties could be used as sources of germplasm which is tolerant to species of the genus Sitona.

Ts. Mihovski, B. Chourcova, D. Mitev

Abstract. During the 2007-2009 period in the experimental field of RIMSA – Troyan, a field trial was carried out with 10 varieties of red clover. Five varieties from Switzerland and four varieties from Japan were studied for Botanical composition, Morphological analysis, Yield of green mass and dry matter and Chemical analysis, comparing them with a Bulgarian candidate variety from Troyan. There were no significant differences with regard to the yields of fresh and dry mass from the different varieties of red clover. The diploid Japanese variety Sapporo was the highest-yielding and it exceeded the candidate variety from Troyan by almost 13% and 11% for the fresh and dry mass, respectively. It had also the best chemical composition, therefore it can be recommended to the practice in the foremountainous regions of Bulgaria. The highest presence of red clover was found in the second experimental year. The portion of stems was predominant in the fresh mass of red clover, followed by that of leaves and flowers.

Abstract: Breeding of coloured cotton varieties will help to solve certain existing ecological problems concerning dyeing of yarn and tissues. In 2007-2009 competitive variety trials were conducted with brown cotton lines. The results obtained showed that, some of them in earliness and productivity were equal to the early and high yielding variety of white cotton Chipan-539. These lines are of great importance for developing of new cotton varieties with high economical and ecological effects in spite of their shorter fiber and lower lint percentage than those of standard cultivars. Some others (created later) had fiber length equal to that of check variety which reveals a possibility for enhancing the fiber quality of brown cotton trough breeding. Lines No 196 and 197 have commercial potential. Very valuable were lines No 105 and 106 with naked seeds, No 201 with naked seeds and natural early fall of the leaf. The variety Izabell is a new achievement in the breeding of a new generation varieties with an exclusive characteristic – naturally coloured brown lint. This variety had high productivity, earliness, suitableness for machine picking, medium fine and short fiber with high uniformity, good elongation and strength. In fiber length and some fiber length characteristics it was inferior to the standard cultivars – Chirpan-539 and Avangard-264. By the other technological fiber properties it was equal to the standards.
