Allelic Interaction

The inheritance of leaf size was studied in crosses involving the large-leafed, L. corniculatus var. vulgaris and the small-leafed, L. corniculatus var. arvensis. Results indicate the genetics of this character to be relatively simple in that it appears to be mainly under the control of alleles at one locus. These alleles show no dominance and there is evidence that the allelic interaction is geometric in nature rather than arithmetic. Backcross ratios of 1:4:1 and 1:2:2:1 were obtained which are indicative of autotetraploid segregation where the chromosomes pair at random. However a factorial hypothesis established wholly on this simple basis does not satisfactorily explain the results. Gene interactions, which at present are unknown, are thought to be involved.Cytological examination of the parent plants showed chromosome pairing to be chiefly as bivalents. Quadrivalent formation was rare. If this species is of autoploid origin as the backcross ratios indicate the process of reversion to the diploid type of chromosome behaviour is fairly complete, and therefore disomic, tetrasomic and disomic-tetrasomic ratios can be expected.

Parental Lines

Two CMS lines, IR 58025A and IR 68888A along with their maintainers and two fertility restorers, LuitR and IR 36R, were evaluated for flower and plant characters during early ahu (February-June) and kharif (July-November) seasons. IR 58025A showed longer stigmata and styles, and higher spikelet Length/Breadth (L/B) ratio while IR 68888A showed broader stigmata and wider glume opening angle in both the seasons. IR 68888A also exhibited higher pollen sterility during early ahu. IR 36R was characterized with broad anthers. LuitR showed longer and broader anthers with more pollen than others. Plant height, flag leaf length, flag leaf width and area were higher in IR 36R. Panicle exsertion was complete in pollen parents whereas it was 78-80% in CMS lines. The widest flag leaf angle was found in IR 58025B during early Ahu and in IR 36R during kharif. Kharif season was more favourable for growth of the plants with higher seed set percentage while floral traits of the CMS lines were better expressed in early Ahu. Manipulation of the seeding sequence of the parental lines in early Ahu is warranted for better seed set provided the seed crop escapes heavy premonsoon showers during reproductive stage. IR 68888A/LuitR was a good combination for pollen dispersal and seed setting.
