Partial Fertility

Three inbred lines of rye (Secale cereale L.) known to be capable of restoring fertility to a cytoplasmic male-sterile line were crossed with the sterile line. The proportions of male fertile, partially male fertile and male sterile plants in F2 and backcross progenies indicated that three dominant restorer genes were present in each line. These were designated Rf1, Rf2 and Rf3, their relative expressivity was Rf1>Rf2>Rf3. Expressivity was dependent upon environment. Partial fertility occurred when certain genotypes carried two of the three alleles as dominant, but was dependent upon genotype and environment.

Secale Cereale L

Five inbred lines of rye (Secale cereale L.) and an open-pollinated rye cultivar were used to pollinate wheat (Triticum aestivum L.) cultivars of differeing crossability. No hybrid seed was produced with the cultivar of low crossability, but with the highly crossable cultivar an average seed set of 65% was obtained. Significant differences in terms of seed set and weight of F1 seed were detected among the inbreds.

Secale Cereale L

Brittlenes of thie stem was found to be one of the more frequently segregating traits in inbred rye lines. In dependenece on the outset cultivated variety this trait appears in the S<sub>2</sub> generation in 4.0-0.6 per cent of the inbred lines. Genetical analysis demonstrated that the trait of brttlenes is determined by one recessive gene denoted by the symbol b<sub>s</sub> (brittlee stem). The bs gene exerts a strong pleliotropic effect on the whole plant, beside brittleness of the stem it causes fragility of the roots, heads and leaves and depresses the general viability of the plants. Anatomilcal observations of thie stem and root sholwed that the b<sub>s</sub> gene causes disturbances in the norirmal lignifcation of the sclerenichyma cells both in shoots and roots, so that these cells are th1i-walled. The tickness of the sclerenchyma layers and the number and size of the vasclcuar in the brittle forms are significantly smaller than in the normal ones. It was found that these changes appear in the bittle forms at the phase of heading of the plants.

Immature inflorescences of Triticum tauschii (Coss.) Schmal. × Secale cereale L. cv. 'Puma' hybrids were induced to callus on Kao's medium supplemented with 5 mg/L 2-4-dichlorophenoxyacetic acid (2.4-D). Plantlets with diploid and tetraploid chromosome numbers were subsequently regenerated from the callus. Chromosome pairing in the diploid regenerants and tetraploid amphiploids was incomplete and the plants were sterile.Key words: Triticum, Secale, chromosome pairing, callus, tissue culture.

Restoration Of Fertility

Six inbred lines of spring rye (Secale cereale L.) and an open-pollinated cultivar of spring rye were crossed with a cytoplasmic male-sterile line of winter rye. The open-pollinated cultivar and all except one inbred line exhibited segregation for fertility restoration. Through further inbreeding, sub-lines of certain breeds were obtained which were homozygous for maintenance of sterility or for restoration of fertility. Environmental effects on the expression of fertility restoration were detected.
