It is considered a complicated issue in breeding programs to obtain stable and high-yielding genotypes to release new genotypes. This study was conducted to achieve a stable high-yielding genotype that is adaptive to climatic conditions of potato-producing regions in Iran. A total of 20 potato breeding lines along with five commercial varieties (Savalan, Agria, Caesar, Luta and Satina) were evaluated in a randomized complete block design with three replicates in the Agricultural Research and Natural Resources Stations of five location (Ardabil, Razavi Khorasan, Karaj, Isfahan and Hamadan) in Iran, for two years (2016 and 2017). Combined ANOVA of yield data for studied genotypes and environments indicates significant differences among potato genotypes, environments, and GE interaction was significant. Thus, the AMMI method and its parameters were used to analyze yield stability. The results indicated that only four interaction principal components were significant (P<0.01), which accounted for 81.2% of the GEI sum of squares. Based on type 1 parameters (SIPC1, FA1, Za1, Dz1, EV1, and Da1), genotypes G7, G10, G14, G20 and G24 were identified as to be stable. Moreover, according to the results of type 2, 3 and 4 parameters, genotypes G2, G6, G7, G14, G15 and G20, as well as cultivars Agria (G24) and Luta (G23), were found to be stable. Genotypes G6, G7, G14, G15, G20, and G24 were stable according to the ASV parameter, and genotypes G6 and G7 were stable based on the MASV parameter. Amongst the stable genotypes identified by the AMMI parameters, while genotype G6 was high-yielding, G14 and G24 (Agria) were moderate-yielding.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83000709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental diets were consisted of with no added enzyme in the control group (G1) and diets supplemented with 0.25 g/kg (G2), 0.50 g/kg (G3) and 1.00 g/kg (G4) phytase enzyme, respectively. Experiment groups were performed in 3 replicates and carried on with 90 days. As a result of the research, it was determined that the addition of phytase enzyme in diets had a positive effect on the growth with weight gain (WG, g), specific growth rate (SGR, %), feed conversion ratio (FCR) and protein efficiency ratio (PER). The growth performance of all phytase enzyme supplemented groups were found to be more successful than the control group (P<0.05). The G4 enzyme group was found to be statistically better than the others (P<0.05).

The target seed spacing (effect of operational speed of the seed disc) and tractor forward speed were evaluated by examining the mean seed spacing, coefficient of precision in spacing, miss index, multiple index, quality of feed index, sowing depth, deviation from row (inter-row spacing), mean emergence time, emergence rate index and percentage emergence. A vacuum single-seed planter was used for sowing at three forward speeds (4.0, 5.4 and 7.9 km h-1) and five target seed spacings (102, 147, 195, 247 and 309 mm). The point dropped in furrow of seed, depth of seed placement, emergence rate and three indices of uniformity in seed spacing and precision coefficients of sowing quality were determined. The planter performed the best performance at the lowest forward speed and the highest target seed spacing. Increasing the forward speed resulted in a shallower sowing depth. The desired planting depth was also obtained at 4.0 km h-1 in all plots. Increasing target seed spacing increased the emergence rate by about 35%, while increasing forward speed decreased the emergence rate by 10%. Sowing at 4.0 km h-1 resulted in the lowest miss, multiple and precision indices (5.1% 2.9%, and 15.3%, respectively), and a quality of feed index as high as 92% was obtained in similar conditions. The results indicated that, with single-seed planters, success may be achieved in a conventional tillage maize production system at a target seed spacing of less than 100 mm and tractor forward speeds of less than 7.9 km h-1, thus satisfying farmers who carry out maize sowing by conventional tillage.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89397452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tobacco is the main income source in most production areas of Turkey. The need for standard cultivars that can meet maximum yield and quality conditions have been increasing. The aim of the present study was to determine cultivar candidates with superior characteristics for Basma type oriental tobacco production areas. Field trials were carried out in Bafra District of Samsun Province, the district with most tobacco production in Mid-Black Sea Region, and Evciler, Karayaka and Gumushacikoy locations where Basma type oriental tobaccos are produced. Experimental design was randomized complete blocks with three replications. The study material consisted of 21 lines selected by morphological characteristics and identified by DNA fingerprinting analysis and four standard cultivars/lines. Chemical analyses were carried out using HPLC method. Stability of genotypes were determined for dried leaf yield, quality index, nicotine and sugar content using regression coefficient (bi), regression constant (a), determination coefficient (r2), coefficient of variation (CV) and deviation from regression (S2d) parameters. Based on their performance for stability parameters and other traits, ERB-6, ERB-7, ERB-11, ERB-13, ERB-16, ERB-18, ERB-21 and ERB-30 lines were prominent ones, and it was concluded that our future studies should be continued using these lines. In conclusion, superior lines and cultivar candidates demanded by growers and sector for production areas of Basma type oriental tobacco were determined.","PeriodicalId":41577,"journal":{"name":"Journal of Agricultural Sciences","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2021-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91069421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
