SOME POSITIVE TRAITS OF DOMESTIC STRAINS OF DIPLOID AND TETRAPLOID WHEAT

Abstract

Pavićević, Lj. (1982): Some positive traits of domestic strains of diploid and tetraploid wheat. - Genetika, Vol. 14, No. 1, 1-11

In this paper the author briefly treats some positive traits of diploid and tetraploid wheat strains grown in the littoral zone of Yugoslavia. These strains are not known in detail so far, nor have they been used in breeding. Yet, according to some traits, they can be useful as source forms for further improvement of related intensive varieties. The author emphasizes the need for the collection and study of these forms to retain them for our culture and agriculture. This is particularly important, because contemporary plant production is increasingly replacing these forms by new intensive varieties and species.

INHERITANCE OF GRAIN YIELD AND STALK ROT RESISTANCE IN MAIZE

Abstract

Ivanović, M., Kraljević-Balalić, M. and Rosić K. (1982): Inheritance of grain yield and stalk rot resistance in maize.- Genetika, Vol. 14, No. 1, 13-20.

Inheritance of grain yield and stalk rot resistance in inbred lines with different stalk rot resistance and their F₁hybrids was investigated. A diallel analysis (5 x 5) method was used. The results indicate that nondominant gene action prevails in yield expression, whereas stalk rot resistance is determined by an approximately equal relationship between additive and nonadditive genetic components.

The stalk resistant parent B14 and VA35 also had the best combining ability for grain yield. This indicates that parallel selection for yield capacity and resistance is possible.

Abstract

Kaul, M.L.H. and Kumar, V. (1982): Mutation genetic studies in rice. III. Agronomic performance of rice mutants. - Genetika, Vol. 14, No. 1, 21-30

The agronomic performance of 20 rice mutants, 5 each of Basmati - 370 and Jhona - 349 and 10 of IR8, was studied over the M₅ - M₇ generations for three years. These improved mutants were selected from 296 mutants initially isolated from 226,430 M₂ plants obtained after induced mutantions using physical (gamma rays) and chemical mutagens (DBS, EMS) singly and in combinations. Although, some height reductions could be achieved in Basmati and Jhona, it was not possible in mutants of IR8. A sufficient earliness could be achieved in Basmati and IR8 mutants, but further earliness was not possible in Jhona. Sufficient gain in grain yield was observed in all the mutants of Basmati and one each of Jhona and IR8. Significant fineness could be achieved in Jhona and IR8, but it deteriorated in the mutants of Basmati. Enhancement in seed protein content of mutants along with increased grain yield led to a net gain in total seed protein production in some of the mutants of these three rice groups. Finally four mutants, two each of Jhona and IR8 were most promising because of their overall improved agronomic performance and high stability. These mutants have a high market value, economic return and breeding utility.

An investigation of the number and position of knobs was made in Yugoslav dent maize, classified as group No. 13 (Corn Belt dents of the United States). Knobs were present in fourteen different positions in these dent populations, with an average knob number of 5.05. Position 9ST was most frequent in the analyzed dent populations; this knob was present in all cytologically analyzed populations (100 per cent).

THE INHERITANCE OF CERTAIN COMPONENTS OF CERNEL YIELD EN WINTER WHEAT

Abstract

Bede, M. and Martinčić, J. (1982): The inheritance of certain components of kernel yield in winter wheat. - Genetika, Vol. 14, No. 1, 39-48.

The combining ability, effect of genes and method of inheritance of the number and weight of kernels per spike for certain varieties and lines of winter wheat was determined by analysis of diallel crosses.

The Osijek line Osk. M.4.13/1 and the Zagreb line Zg 5328 had the greatest OKS value for the number of kernels per spike; the former line also had the greatest kernel weight per spike, which indicates the strong possibility of using this line as a parent in a breeding programme to increase the fertility of winter wheat.

Analysis of the components of genetic variation and regression analysis show that the greater part of the genetic variation of this characteristic is accounted for by the dominant component, while superdomination is decisive in the inheritance of the number and weight of kernels per spike.

The number and weight of kernels in the line Osk. M.4.13/1 and the Partizanka variety are mainly determined by dominant genes and in the line Osk. 126 mainly by recessive genes.

Abstract

Stančević A. (1982): Biological characteristics of new quince hybrids. - Genetika, Vol 14, No. 1, 59-63.

In order to create high-quality quince cultivars which would also be self-fertile, crosses were made using five different combinations of cultivars, and as a result 850 hybrid seedlings were obtained. Three of them were singled out: I/I, 1/21 and II/25, for their large, attractive fruit of excellent technological characteristics and for abundant cropping. Their properties are presented in this paper.

Abstract

Šopova, M., Apostolovski, B., Efinski, D. and Ristevski, B. (1982): A case with translocation t(3p¯, 7q⁺). - Genetika, Vol. 14, No. 1, 65-70.

The karyotype of a patient with severe mental retardation and multiple congenital molformations was found to be 46, XX t(3p¯, 7q⁺). The propositus had balanced translocation of the distal part of the short arm of chromosome 3, which was translocated distally to the long arm of chromosome 7. The severe mental retardation and multiple congenital malformations are suggested to be due to deletion of chromosome 3 and to eventual deletion of chromosome 7.

Abstract

Đuričić, E., Kilalić, T. and Kantardžić Dž. (1982): Action of anticonvulsant drugs on the chromosomes of human lymphocytes. - Genetika, Vol. 14, No. 1, 71 -76.

Chromosomal breaks and pulverisation (chromatid fusion) were observed in patients treated with various anticonvulsant preparations. Three groups of patients were studied: (1) Patients treated with a combination of barbiturates, hydanphene and carbamazepine; (2) patients who were treated with barbiturates and hydanphene; (3) patients who were treated with carbamazepine; and (4) children up to ten years of age who had been treated for a long period with hydanphene. Human lymphocytes were prepared for cytologic analysis by the Murched method and marked by means of the G - banding technique. Chromosome breaks were of the chromatid type. The breakage frequency per individual cell was varied, most frequently amounting to one or two chromosomes per cell. Rarely, the maximal number reached one half of the chromosomal set. The number of breaks per chromosome was equally variable, from one break on one chromatid, to damage of both at the same or different levels.

Abstract

Knežević, J. and Simić, D. (1982): Induction of phage A by bleomycin and nalidixic acid in the lexA mutant of Escherichia coli K12. - Genetika, Vol. 14, No. 1, 77-91.

The effect of two SOS inducing agents, bleomycin and nalidixic acid, on the induction of prophage X and the kinetics of viral represser inactivation in vivo were studied inlysogenic cells of E. coli K12 and its lexAl derivative in the exponential phase of growth. The results obtained indicate that in the lexAl mutant viral represser inactivation by nalidixic acid requires only proteolytic activation of basal levels of the recA protein in the cell. This was not the case with bleomycin.
