PROMENE VARIJABILNOSTI PRINOSA ZRNA<br />
PRI SESTRINSKOM UKRŠTANJU SOJE<br />
Mirjana Srebriæ<br />
Institut za kukuruz «Zemun Polje», Beograd – Zemun<br />
Prouèavali smo promene varijabilnosti prinosa zrna po biljci soje kod potomstava<br />
sestrinskih ukrštanja u odnosu na potomstva njihovih majki. Kao roditelji za sestrinska<br />
ukrštanja korišæene su tri najprinosnije F3 linije razvijene iz ukrštanja sorti KUNITZ x<br />
KADOR. Svaka od ovih linija korišæena je po jednom kao materinska komponenta.<br />
Testiran je prinos zrna po biljci potomstava sestrinskih ukrštanja i potomstava njihovih<br />
majèinskih linija. Promene varijabilnosti prinosa zrna su ocenjene preko koeficijenata<br />
varijacije (genotipskih i fenotipskih). Varijabilnost prinosa zrna po biljci je uglavnom<br />
bila blago poveæana kod potomstava sestrinskih ukrštanja u odnosu na potomstva<br />
njihovih majki.<br />
THE CHANGES OF SEED YIELD VARIABILITY<br />
IN SOYBEAN SISTER CROSSINGS<br />
The objective of experiment was the changes of seed yield per plant in progenies to F3 soybean sister crosses in compare to progenies of their maternal lines. The three lines<br />
with the highest yield, derived from crossing KUNITZ x KADOR cultivars were utilized<br />
as parents. Each derived line was used as a maternal component once.<br />
The grain yield per plant of both, lines and sister crosses of three combinations was<br />
tested. The changes of grain yield variability were evaluated by using coefficients of<br />
variation (genetic and phenotypic). The variability of soybean seed yield per plant was<br />
mostly delicate increased in progenies of sister crossings when compared to their maternal<br />
lines progenies.
