“…The heterosis observed in combination with this mutant is caused by the heterozygotic condition of a very low number of gene pairs involved . Fasciated pea mutants have been known for a long time ; they were often described (BOEKER, 1930 ;LUTKOV, 1937 ;LAMPRECHT, 1952 ;GELIN, 1954 ;SCHEIBE, 1954a, b ;MARX and HAGEDORN, 1962 ;ENKEN, 1966 ;GOTTSCHALK, 1966) . Although BOEKER obtained a high seed production in his material he failed to develop a fasciated commercial variety.…”

The favourable yielding capacity of a group of X-ray induced Pisum sativum mutants makes them attractive for pea breeding. The fasciated mutant 489C produced as much as 32-92 % more seed than the corresponding values of the initial line during the past 4 years . Mutants 68C and 1201A cannot exploit their favourable properties . After incorporation in different genetic backgrounds the genes in question can be expected to induce better productivity . The small-grained mutant 176A having a very good seed set could be of interest to canning industry . The early flowering mutant 46 cannot be used in practical breeding because of its heterogeneous yield properties in subsequent generations .Hybrids between these mutants were made in order to combine their useful characters . The productivity of these hybrids and their parental lines was studied and compared with the initial line . Hybrids between 176A x 68C and 1201A x 68C did not show heterosis for any characters . Hybrids of all mutants with the fasciated 489C, however, showed a marked heterosis effect for increased vigour and stem length resulting in a conspiciously high seed production .

“…Formation of a fasciated stem does not necessarily cause better yield . An X-ray induced fasciated mutant studied by GELIN (1954) yielded less than its initial line . This is equally true for two other fasciated mutants arisen in our X-ray and neutron experiments .…”
