GAJENJE KUKURUZA PDF

0 Comments

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.

OPLEMENJIVANJE KUKURUZA NA PRINOS I KVALITET.

Due to their more favourable stability parameter values, medium-early hybrids can be recommended for low-intensity cultural practices and stressful environments. Half of the other hybrids showed significant values, whereas the other half showed negative values Table 2.

Users should refer to the original published version of the material for the full abstract. Grain yield and its components were assessed in 11 maize hybrids with different lengths of growing season FAO maturity groups using analysis of variance and regression analysis at three different locations in Western Serbia. Field Crops Research, Results of investigation shows a possibilities to increase yield and total maize production. The lowest highly significant bi value was detected in HY02, and the value closest to the average in HY Can J Plant Sci Weed Science44 2 In terms of stability parameters, HY05 was comparable to the medium-early hybrids, with its grain yields kukuruzx certain locations corresponding to those of late-season hybrids.

Significant GEI results from changes in the relative ranking of genotype performance across environments, and it affects breeding progress Pham and Kang, Moreover, if the regression coefficient does not show significant differences across genotypes, regression lines can gajenjw grouped, with only deviation from regression being used as a stability parameter for genotype classification.

A significant interaction was observed between all traits and the environment. Weed Sci37, str.

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.

However, users may print, download, or email articles for individual use. Individual values were not significantly different from kukuruzza average value in any hybrid.

The significantly different value of bi in HY02 in the first year suggests greater-than-average stability of gjenje hybrid as compared to the other hybrids tested. The model proposed by Eberhart and Russell has been widely employed in the last several decades mostly due to the classification of variation in genotype performance into predictable regression and unpredictable deviation from regression components.

The stability parameters indicate that this hybrid exhibits a specific response to the particular agroenvironmental conditions i.

Herbologia6, gajenjee. This abstract may be abridged. Crop Science 6, The traits analysed showed significant interaction with the environment.

Medium-late hybrids had higher yields and showed a better response to favourable environmental conditions compared to early-maturing hybrids.

The regression coefficient gajeenje was highest in medium-season HY06, and lowest in medium-early HY Conversely, the hybrids giving high values for the trait, with HY03 and HY06 as representatives of lower maturity groups, had coefficient values greater than 1 and, occasionally, significantly higher values.

In contrast, the values for the other hybrids were negative or significant. Crop Science, 11, Likewise, genotypes having a high value of S2di are considered highly unstable, whereas those with low values as highly gajejne. Where Do We Stand?

The hybrids belong to different maturity groups, viz. Setve je obavljena u provoj polovini aprila u obe godne na svim lokalitetima.

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. The association between lower average values of a particular trait and greater than average stability kukkuruza also observed in ear length.

Materials and methods Eleven double-way maize hybrids developed at the Zemun Polje Maize Research Institute were assessed. Poljoprivredni fakultet, doktorska disertacija.

AMMI analysis of factorial designs. Nepovoljne vrednosti patrametara stabilnosti registrovane su kod hibrida kasnijih grupa zrenja u odnosu na ranije grupe zrenja to jest FAO vs FAO In this model, a regression coefficient greater than 1. The results obtained should point to the possibility of using short-season hybrids instead of medium-late ones, given the balance between yield, yield components and other agronomically important traits, on the one hand, and values of stability parameters, on the other.

Weed Research35 5: Sowing was conducted in the first half of April in both years at all locations. The model proposed by Eberhart and Gxjenje interprets the variance of deviations from regression as a measure of cultivar stability and the linear regression coefficient bi as a measure of cultivar adaptability. Among medium-season hybrids, HY06 gave higher yields and had less favourable values of stability parameters compared to medium-late hybrids.
