120 ZBORNIK ABSTRAKATA III KONGRESA GENETIÈARA SRBIJE IV-Pos-3 Subotica, 30. novembar - 4. decembar 2004. PRODUKTIVNOST NEKIH GENOTIPOVA PŠENICE M. Biberdiæ 1 , M. Ðorðeviæ 2 , S. Barac 1 , N. Deletiæ 1 i S. Stojkoviæ 1 1 Poljoprivredni fakultet Univerziteta u Prištini, Lešak 2 Zavod za poljoprivredu, Leskovac Pšenica je naša najvanija biljna vrsta, a pšenièno zrno osnovni elemenat ishrane ljudi. S obzirom na stalni rast ljudske populacije i potrebom za hranom, nameæe se potreba za obezbeðenjem dovoljnih kolièina zrna ove biljne vrste. Prinosi koje sorte postiu su razlièiti i zavise od više faktora, a najviše od genotipa, agroklimatskih uslova i primenjene tehnologije proizvodnje. Stoga je cilj ovoga rada bio da se utvrdi produktivnost više genotipova pšenice u junom delu <strong>Srbije</strong>, putem makroogleda. Tako je u 2000. i 2001. godini u makrooglede bilo ukljuèeno 20 genotipova pšenice. Rezultati istraivanja pokazuju da su se prinosi znatno razlikovali po godinama i ta razlika je u proseku iznosila oko 1300 kg/ha. Proseèni dvogodišnji rezultati pokazuju da su najveæe prinose ostvarile sorte Toplica, Stamena, Evropa, NS-rana 5 i Renesansa. Najnie prinose imale su sorte Tiha, Sara, Sreæa i Mina. PRODUCTIVITY OF SOME WINTER WHEAT GENOTYPES Winter wheat is the most important plant species in our country, and wheat grain is a basic element of human diet. There is a need for sufficient supplies increase of human population. Yields given by different genotypes are affected by many factors, but mostly by genotype, climatic conditions and applied growing practice. There fore, the aim of this study was to establish productivity of many winter wheat genotypes in southern Serbia, through macro trials. A set of 20 wheat genotypes was studied in 2000 and 2001. The results showed the difference of grain yield mean between the investigated seasons, and that difference amounted about 1300 kg/ha. The average yield was the highest in cultivars Toplica, Stamena, Evropa, NS-rana 5, and Renesansa. The lowest grain yield was given by cultivars Tiha, Sara, Sreæa, and Mina.
IV-Pos-4 ZBORNIK ABSTRAKATA III KONGRESA GENETIÈARA SRBIJE 121 Subotica, 30. novembar - 4. decembar 2004. EKSPERIMENTALNO UTVRÐENA DUINA TRAJANJA, PROSEÈNI I MAKSIMALNI INTENZITET NALIVANJA ZRNA GENOTIPOVA PŠENICE RAZLIÈITE RANOSTASNOSTI Milka Brdar, Marija Kraljeviæ-Balaliæ i B. Kobiljski Nauèni institut za ratarstvo i povrtarstvo, Novi Sad Prinos zrna pšenice (Triticum aestivum L.) je delom uslovljen krajnjom masom suvog zrelog zrna, koja je u velikoj meri odreðena intenzitetom i duinom trajanja procesa nalivanja zrna. Cilj istraivanja je poreðenje eksperimentalno utvrðene krajnje mase suvog zrelog zrna 5 grupa genotipova pšenice razlièite ranostasnosti (ekstra rane, srednje rane, srednje kasne, kasne i kontrolna grupa najprinosnijih NS sorti) sa eksperimentalno utvrðenim proseènim i maksimalnim intenzitetom, te duinom trajanja nalivanja zrna u razlièim uslovima sredine. Korelacioni koeficijenti su upotrebljeni u pokušaju da se odredi koji parametar nalivanja zrna ima veæi uticaj na krajnju masu suvog zrelog zrna. U kod nas uobièajenim uslovima sredine (2002.) je krajnja masa suvog zrelog zrna bila u jakim pozitivnim vezama sa proseènim i maksimalnim intenzitetom i u jakoj negativnoj vezi sa duinom trajanja nalivanja zrna. Najveæe krajnje mase suvih zrelih zrna postigli su srednje kasni i genotipovi kontrolne grupe. Korelacije izmeðu krajnje mase suvog zrelog zrna i duine trajanja, te proseènog intenziteta nalivanja zrna su bile znaèajno pozitivne u nepovoljnim uslovima sredine (2001.). Novosadske sorte i ekstra rani genotipovi su imali najveæe mase suvih zrelih zrna. Intenzitet i duina trajanja nalivanja zrna su obièno u negativnoj korelaciji. Uticaj parametara nalivanja zrna na krajnju masu suvog zrelog zrna nije jednak u razlièitim uslovima sredine, tako da bi mogla biti bitnija sposobnost genotipa da u nepovoljnim uslovima sredine niske intenzitete nalivanja zrna nadomesti produenjem akumulacije suve materije. Za opisivanje ovih procesa bi eksperimentalno utvrðeni proseèni intenzitet nalivanja zrna mogao biti vaniji parametar od maksimalnog. OBSERVED DURATION AND AVERAGE AND MAXIMUM GRAIN FILLING RATES IN WHEAT GENOTYPES OF DIFFERENT EARLINESS Grain yields of wheat (Triticum aestivum L.) are influenced partly by final grain dry weight, which is largely determined by the rate and duration of the grain filling process. A study was undertaken to compare the observed final grain dry weight of five groups of wheat genotypes differing in earliness (extra early, medium early, medium late, late and a control group of high-yielding NS cultivars) with the observed duration and average and maximum rates of grain filling in two different environments. Correlation coefficients were used to determine which grain filling parameter had more influence on final grain dry weight. In an environment common for our country (2002), final grain dry weight as strongly positively correlated with the average and maximum rates and strongly neg - atively correlated with the duration of grain filling. The medium late and control groups had the highest final grain dry weights. Correlations between final grain dry weight and the duration and average rate of grain filling were positive in an unfavorable environment (2001). The NS cultivars and extra early genotypes had the highest final grain dry weights. The rate and duration of grain filling are usually negatively correlated. The influence of grain filling parameters on final grain dry weight is not the same in different environments, so the ability of the genotype to compensate for the low grain filling rate with grain fill prolongation in unfavorable environments might be more important. The observed average grain filling rate is probably more important as a parameter for describing these processes than the maximum one.
