Abstract
Đorđević, B. and R. Đorđević(1992): Mitotic cytotoxicity in HeLa cells by mild hyperthermia and cloroquine combined. - Genetika, Vol. 24, No. 1, 1-7.
Evidence is presented that 0.1 mM chloroquine and mild hyperthermia are highly toxic for mitotic HeLa cells. For a few hours after setting up synchronous cultures of mitotic cells, the cultures remain sensitive to the combined action of heat and chloroquine. The mechanism of heat-chloroquine interaction, and the clinical implication of our findings are discussed.

Stefanović (1992): The frequency of acrocentric chromosome associations in phytohemagglutinin stimulated lymphocytes in Balkan endemic nephropathy patients and their clinically healthy relatives. - Genetika, Vol. 24, No. 1, 13-18.
The frequency of acrocentric chromosome associations in phytohemagglutinin stimulated lymphocytes was investigated in 7 patients with Balkan endemic nephropathy (BEN) and initial chronic renal failure, 6 clinically healthy relatives of BEN patients and 8 controls from the city of Niš.
No significant difference was found in the frequency of acrocentric associations, i.e. in relevant parameters for this phenomenon in the investigated groups.
The occurrence of an increased frequency of acrocentric chromosome associations, previously found in some hereditary diseases, is not typical of BEN.

Eight sunflower inbred lines were crossed and F1 hybrids were produced. The inheritance of nitrate reductase activity (NRA), proline content, transpiration intensity and relative water content (RWC) were evaluated in plants grown under water stress and control plants. Significant differences occurred between inbred lines and F1 hybrids with respect to all tested traits, except for RWC in the control. The mode of inheritance was intermediate, dominant or superdominant, depending on the tested traits and cross combination. The genotypic (GCV) and phenotypic (PVC) coefficients of variation and heritability in the broad sense were considerably high.

Abstract
Babić, M. and Z. Pajić (1992): Effect of genotype x environment interaction on expansion volume in popcorn hybrids (Zea mays L.) - Genetika, Vol. 24, No. 1, 27-32.
The effects of ecological factors on popping quality were investigated. Nine popcorn hybrids were chosen and sown in two locations (ZPSC611k, ZPTC610R, ZPTC601k, P608, Exp72107, Exp63106, Ag7566, Exp72122).
Variance analysis of the investigated traits (popping volume and number of kernels per 10 grams) showed very significant differences among the hybrids, the locations where they were sown and hybrid x location interaction. This suggest that, beside genetics variance, ecological variance as well as variance of genotype x environment (location) interaction had great effects on expression of the mentioned traits.
The correlation coefficient between the number of kernels per 10 grams and popping volume had a positive value (0.193). This means that, as the number of kernels per 10 grams increased, the kernels were smaller and contained more hard endosperm which resulted in an increase of popping volume and vice versa

Abstract
Draganić, M. and B. Borić (1992): Prediction of maize stalk resistance to rot based on the degree of resistance of parent components. - Genetika, Vol. 24, No. 1, 33-40.
The resistance of six inbred lines and 15 F1 hybrids to the stalk rot pathogens Fusarium culmorum and Fusarium sporotridioides var. tricinctum in field conditions was investigated in this work.
The degree of resistance of the maize stalk of the hybrid represented the actual resistance, while the theoretical resistance of the hybrid was calculated on the basis of the degree of resistance of parent components according to the formula TOF1 = 3P1 + P2/4. The equivalence of the actual and theoretical resistance was assessed using the Hi2 test for n-1 degrees of freedom.
The results showed that the formula TOF1 = 3P1 + P2/4 is suitable for the calculation, i.e. prediction of the resistance of the maize stalk to the cited rot pathogens.

Abstract
Jocković, Dj., M. Vidić and M. Hrustić (1992): Inheritance of the number of branches in soybean. - Genetika, Vol. 24, No. 1, 41-48.
Diallel crosses of four diverse soybean genotypes were evaluated in order to study the mode of inheritance, heritability, combining ability and components of genetic variability for the number of branches per plant in the F1 and the F2 generation. Significant differences in the number of branches per plant were found between the parents and their hybrids. The inheritance of the number of branches per plant was most frequently heterotic in the F1 and intermediate, partially dominant and dominant in favor of the parent with fewer branches in the F2 generation. The obtained values of the broad-sense heritability were from 0 to 18% and 77% for the narrow-sense heritability. The non-additive component of genetic variance was more important than the additive component for the inheritance of the number of branches per plant in the F1 generation while the opposite occurred in the F2 generation.

EFFECT OF ENVIRONMENTAL FACTORS ON CHANGES IN CARBOHYDRATE COMPOSITION OF SWEET CORN (ZEA MAYS L. SACCHARATA)

Abstract
Pajić, Z., M. Babić and M. Radosavljević (1992): Effect of environmental factors on changes in carbohydrate composition of sweet com (Zea mays L. saccharata). - Genetika, Vol. 24, No. 1, 49-56.
Sweet corn differs from field corn by a mutation at the sugary (Su) locus on chromosome 4; sweet corn has the gene (sit) at this locus. The (sit) mutation affects the endosperm "composition by causing it to accumulate twice as much sugar and eight to ten times more water-soluble polysaccharides (WSP) than normal field corn at the immature (edible) stage when it is normally consumed (Creech, 1968).
However, standard sweet corn, sugary-su, has one serious limitation, namely, the relatively short period the kernels remain at peak eating quality. Not only is this quality lost very quickly after harvest, but it can be lost in the field if the corn is not harvested at precisely the right time. Often, the acceptable harvest time is as short as one day (Ma rshall, 1987).
The analysis of variance for content of sugars during, maturation under different conditions of growing sweet corn hybrids, showed that there were significant and very significant differences in the proportion of individual sugars (fructose and glucose). The results indicated that there were very significant differences in the content of fructose, glucose and sucrose at different stages of maturation (10, 15, 20, 25 and 30 days after pollination). It was found in both years of investigation that the content of glucose and fructose was high in the initial phases, and that with maturity it decreased. The content of sucrose was low in the early stages. It gradually increased and reached a peak 25 days after pollination, in both hybrids ZPSC213su and ZPSC301su and years of investigation.

DIALLEL ANALYSIS IN LABLAB BEAN (DOLICHOS LABLAB MEDIK)

Abstract
Singh, S.P. and J.P. Srivastava (1992): Diallel analysis in lablab bean (Dolichos Lablab, medik). Genetika Vol. 24, No. 1, 57-68.
The present investigation was carried out to estimate the different gene systems involved in the expression of different characters in lablab bean (Dolichos lablab Medik). A 6 parent diallel excluding reciprocals in F1 was analysed for pod yield and its 5 component traits. Dialel assumptions were fulfilled for all the characters. Component analysis and a Wr-Vr graph revealed a major effect of partial dominance for all the characters except seeds/pod.
The distribution of array points in the Wr-Vr graph were well in agreement with the standardized deviation graph. The early parent '7001' which is very early in flowering and maturity possessed maximum recessive alleles and thus indicates that earliness is governed by recessive genes. Parents '6802' and 'Rajani' possessed maximum dominant genes. On the basis of rank index based on breeding value and per-se performance of the parents, '6802', 'Rajani' ' and 'KT2' were promising. Heritability estimate (ns) was high for all the characters except seeds/pod. The low heritability and over-dominance for seeds/pod may be confounded at least in part with complementary type gene action and genetic diversity among parents. Considering the gene action involved, the breeding method was discussed.
