Za intenzivno gajenje hibrida kukuruza neophodno je, pored komponenti prinosa i drugih agronomski važnih osobina biljke, za objektivnu ocenu njihovih. Ministri Evropske unije odobrili su gajenje kontroverznog genetski modifikovanog novog roda kukuruza, TC američke kompanije DuPont Pioneer. S druge strane, domaće životinje troše tokom uzgoja velike količine semena kukuruza, što sa obzirom na ograničen zemljišni fond obično znači učestalo gajenje.

EBSCOhost | | OPLEMENJIVANJE KUKURUZA NA PRINOS I KVALITET.
With the exception of HY08 and HY10, the other hybrids showed negative values. The highest and highly significant regression coefficient in the first year, relative to the average, was found in kukuuruza HY10, whereas medium-season HY08 and HY05 had significant values.
Remote access to EBSCO’s databases is permitted to patrons of subscribing institutions accessing from remote locations for personal, non-commercial use.
Photosyinthetica29, str. Weed Technol5: However, remote access to EBSCO’s databases from non-subscribing institutions is not allowed if the purpose of the use is for commercial gain through cost reduction or avoidance for a non-subscribing institution.
Each hybrid was sown in four rows per replication with 17 hills each with two plants per row at a spacing of 57 cm, making up a plant density of 50, plants ha However, the fact that the independent variable environmental index in this model can be used before the experiment may be considered a limitation to interpreting deviations from regression as being a measure of cultivar stability.
Herbologia, Sarajevo1, br.
kukueuza Journal of Applied Ecology38 4: Australian Journal of Agricultural Research, 14, Grain yield and its components were assessed in 11 maize hybrids with different lengths of growing season Gajenme maturity groups using analysis of variance and regression analysis at three different locations in Western Serbia.
Crop Science, 28, Help Center Find new research papers in: Regression coefficient bi values for grain yield mostly suggested no significant differences relative to the mean.
A strategy to reduce GEI involves selecting cultivars with a better stability across a wide range of environments in order to better predict their behaviour Eberhart and Russell, ; Tai, Setve je obavljena u provoj polovini aprila u obe godne na svim lokalitetima. Namely, cultivars that have regression coefficients greater than unity would be more adapted to favourable growing conditions, those with regression coefficients less than unity would be adapted to unfavourable environmental conditions, and those with regression coefficients equal to unity would have an average adaptation to all environments.
The traits analysed showed significant interaction with the environment.
No warranty is given about the accuracy of the copy. Weed Science44, str. On the other hand, domestic animals require a lot of corn and considering the limited landarea, that often demands repeated sowing of ganenje continuous croppingconsequently leading to higher pest damages. This abstract may be abridged. Users should refer to the original published version of the material for the full abstract. Monitoring showed that crop rotation gives good results.
Using this criterion, Flores et al. The rationale and approach. The lowest highly significant bi value was detected in HY02, and the value closest to the average in HY Journal of Central European Agriculture,15 4p.
The model proposed by Eberhart and Russell interprets the variance of deviations from regression as a measure of cultivar stability and the linear regression coefficient bi as a measure of cultivar kuluruza.
Herbologia6, str. The hybrids belonging to low maturity groups have higher adaptability, but show a low response to the environment and, hence, frequent inability to make kukuurza of favourable lukuruza Troyer Introduction Identification of genotypes with a high potential for yield and stability across environments is an essential task in plant breeding.
The statistically non-additive genotype x environment interaction suggests dependence of yield differences among cultivars on the environment Yue et al. Due to their more favourable stability parameter values, medium-early hybrids can be recommended for low-intensity cultural practices and stressful environments.
Crop Science31, str. Field Crops Research49 However, this concept is of less importance to breeders and agronomists, who prefer genotypes with high yields and the potential to respond positively to agronomic inputs and favourable environmental conditions Becker, Weed Res35, str.
