Plant genetic resources of any country represent its natural wealth. Gene Bank
of the Maize Research Institute "Zemun Polje" with over 5,000 samples
represents national guardian of such. Local maize populations, tributing to their
diversity, represent a key source of desirable traits for breeding programs, such
as nutritional values for protein, starch and lipids. Today’s corn hybrids are
based on a narrow genetic base, where in race for yield, often insufficient
attention is paid to the nutritional composition of the hybrids themselves.
Correct selection of material from the Gene Bank can only be achieved with
pre-breeding selection. Such prebreeding would cover wide material and
should detect and reduce it to a desirable and more acceptable volume that can
further be introduced into commercial breeding programs. This paper covered
analysis of protein, starch and lipid content in grain of 31 local maize
populations, crossed with two commercial testers ZPL-217 (BSSS) and ZP...L-
255/75-5 (Lancaster Sure Crop) with line x tester method used for combinig
ability calculation. According to the results the best combiner for higher lipid
content is A3 landrace with a GCA value of 0.33*, for protein content landraces
A9 and A 38 with GCA values of 0.51* and 0.57*, respectively, were found.
As for populations A 17 and A 37 with the GCA values of 1.52* and 1.36*,
respectively, they proved to be the best combiners for starch. Mentioned
populations showed significant GCA values with a probability level of 0.05,
showing their possible significance in further breeding application.
