The objective of this paper was to determine relationship between grain yield and morphological traits, in 8 inbred lines and their hybrids. Strong genetic and phenotypic correlations were found between grain yield and other studied traits, except between grain yield, on one side, and kernel row number where we found medium correlations. Between other studied traits, the highest values of genotypic and phenotypic coefficient of correlations were found between ear length and cob weight.

Ogled je postavljen u tri vegetacione sezone na jednom lokalitetu (Begeč), po split-plot sistemu u pet ponavljanja. Uticaj malčovanja ispitivan je na sortama krompira Cleopatra i Riviera. Sadnja je obavljena mašinski, jedna krtola po kućici, na međuredni razmak od 65 cm, a razmak u redu 30 cm. Analizirane su broj krtola po biljci, masa krtola po biljci (g) i prinos mladog krompira (kg/ha). Analiza varijanse je urađena po split-plot modelu na osnovu prosečnih srednjih vrednosti. Poređenje srednjih vrednosti urađeno je primenom LSD testa. Visoko značajan efekat tretmana (nastiranja) utvrđen je za sve tri proučavane osobine. Obe proučavane sorte ostvarile su statistički značajno veći prinos i masu krtola po biljci pri primeni nastiranja, dok je osobina broj krtola po biljci bila veća na kontrolnoj varijanti, ali razlika između kontrole i tretmana nije bila statistički značajna. Statistički značajno više vrednosti za sve tri proučavane osobine ustanovljene su kod sorte Riviera. Na osnovu dobijenih rezultata može se zaključiti da primena nastiranja ima pozitivan uticaj na prinos mladog krompira, što pruža mogućnost za širu primenu ove specifične agrotehničke mere u proizvodnji mladog krompira.

Superior position of maize is due to his very wide and variety utilisation and because of that, the main goal of all maize breeding programs is to obtain new inbred lines and hybrids that will outperform the existing hybrids with respect to a number of traits. For efficient selection of grain yield, like the most important economic trait, in regard to its on the great influence the environmental factors, has complex mode of inheritance and low heritability, is necessary to know relation between grain yield and morphological traits which are influencing on the grain yield. One of the objectives of this paper was to determine relationship between grain yield and morphological traits. For these purpose two testcross populations which are formed by crossing progenies of NSU1 population after 16 cycles of phenotypic recurrent selection and two testers were tested. In both studied populations significant medium strong correlati...

In view of this, the objective of this paper was to study combining abilities and determine the mode of inheritance and gene effects for the main agronomic character, grain yield, and its components, kernel row number and kernel number per row. Six inbred lines were used in the study, three of which originated in the U.S., while the other three were developed at the Institute of Field and Vegetable Crops in Novi Sad. Kernel row number was inherited by superdominance, partial dominance, complete dominance and intermediacy. The mode of inheritance of kernel number per row and grain yield was superdominance. Additive gene action had the greatest influence on the expression of kernel row number, while the other two traits were influenced the most by nonadditive gene.

In testcross combination NSU 1 × 568/II NS, oil content had pozitive genetic correlation with all studied traits. At the second studied population, NSU 1 × B73, oil content had positive correlation only with ear height and ear lenght, while correlation between oil content and plant height and kernel row number were negative. Between other studied traits, at 568/II testcrosses, the strongest relationship was found between plant and ear height, and at B73 testcrosses between plant height and ear lenght. In NSU 1 × 568/II NS, oil content had positive phenotypic correlations with all traits, except, with a 104 GENETIKA, Vol. 39, No. 2, 103 -112, 2007. kernel row number. In the second studied population, phenotypic correlations between oil content and all traits (except ear lenght) were negative. The highest value of phenotypic correlation between another studied traits, in NSU 1 × 568/II NS testcross combination, was found between plant and ear height, and in NSU 1 × B73, between plant height and kernel row number.

The results indicated significant differences among the parents for general combining ability (GCA) and crosses for specific combining ability (SCA) for spike length. However, highly significant differences for the general (GCA) and specific (SCA) combining ability in the F1 generation denoted that spike length had resulted from the genes with additive and non-additive, i.e. dominant impact. The absence of interallelic interaction between the genes determining the expression of spike length was concluded from the regression analysis. The regression line intercepts the Wr axis below the origin in F1 indicating overdominance over an average of all arrays.

Human intervention for the improvement of crops, trees and livestock is nothing new: for millennia, humans have bred, crossed and selected those varieties, ecotypes and breeds that were more productive, and better adapted, but conventional breeding practices can now be complemented by a number of new and powerful techniques. Modern biotechnology represent a new aspect of biological and agricultural science which provides new tools and strategies. New techniques of molecular biology, including recombinant DNA and cell fusion, have became a powerful research tools in biology. As the foundations of biotechnology, these techniques hold great promise for the development of new products derived from plants, animals and microorganisms to be employed in industry and agriculture. Molecular biotechnology, including recombinant DNA, transplastomic plants, projectile ...

In testcross combination NSU1 × 568/II NS, oil content had positive genetic correlation with all studied traits. At the second studied population, NSU1 × B73, oil content had positive correlation only with ear height and ear length, while correlation between oil content and plant height and kernel row number were negative. Between other studied traits, at 568/II testcrosses, the strongest relationship was found between plant and ear height, and at B73 testcrosses between plant height and ear length. In NSU1 × 568/II NS, oil content had positive phenotypic correlations with all traits, except, with a kernel row number. In the second studied population, phenotypic correlations between oil content and all traits (except ear length) were negative. The highest value of phenotypic correlation between another studied traits, in NSU1 × 568/II NS testcross combination, was found between plant and ear height, and in NSU1 × B73, between plant height and kernel row number. .

was estimated in F1 generation. The results indicated significant differences among the parents for general
combining ability (GCA) and crosses for specific combining ability (SCA) for spike length. However, highly
significant differences for the general (GCA) and specific (SCA) combining ability in the F1 generation denoted
that spike length had resulted from the genes with additive and non-additive, i.e. dominant impact. The absence
of interallelic interaction between the genes determining the expression of spike length was concluded from the
regression analysis. The regression line intercepts the Wr axis below the origin in F1 indicating overdominance
over an average of all arrays.
