Polyploidy in Insect Evolution
1980Of all living organisms insects are the group with the highest number of existing species. It is, of course, true that a fraction of the total number of insects has been cytologically studied. Polyploid forms are rare exceptions among them. Polyploidy in insects is always associated with the parthenogenetic mode of reproduction.

AMONG the herbage crops, cocksfoot (Dactylis glomerata L.)1 and bird's foot trefoil (Lotus corniculatus L.)2 have been shown to be autotetraploids, and lucerne (Medicago sativa L.), having also given segregation ratios which can best be interpreted as tetrasomic, may be regarded as an autotetraploid3.

Compared to animals, polyploidy is successful in plants because their developmental processes are much simpler (Fankhauser 1945; Stebbins 1950). The actual incidence of frequency in various plant lineages has been proved difficult to determine, despite numerous attempts over the past 100 years to estimate the frequency of polyploidy in plants (Table 3 ...

Polyploidy and Agriculture: Summary
1980As an outsider to this field with modest understanding of Polyploidy and its implications to agriculture, there is little that I can add to the discussion. The contributions which compose this session on the relevance of Polyploidy to agriculture have provided a wealth of information on a broad array of subjects ranging from the relation between ...

POLYPLOIDY has attracted interest from three somewhat (listilict groups of workers on account of: (a) its significance in evolution, (b) its importance in plant breedimig, and (c) its special chromosome miechanisnis, with their significance for the elucidation of general cytological problems.
