Grain yield mutations induced by ethyl methanesulfonate treatment of oat seeds

Induced Mutations in Plant Breeding

“…One out of 160 EMS-induced mutant lines proved to have a positive deviation for grain yield as compared to the mother variety (Arias and Frey 1973).…”

Magnitude and distribution of genetic variation from mutagenesis and hybridization

“…These mutagens were effective in inducing variability for heading date, plant height, and spike length in wheat (Khadr and Shukry, 1972), and the induced variability generally was distributed equally around the check population mean. Arias and Prey (1973) Borojevic (1965Borojevic ( , 1966Borojevic ( , 1969Borojevic ( . and 1971 Several researchers (Borojevic, 1965: Wellensiek, 1965and Gaul, 1970) have postulated that sterility may contribute to the general reduction in mean yield associated with mutagen treatment.…”

“…Arias and Prey (1973) For example, if a mutation for early maturity occurred in a check line with late maturity it is unlikely that it would be classified as a mutant for early maturity. In light of the genetic variation observed in P^, the number of mutants was also determined on the basis of the least significant differ ence (LSD).…”

Studies on the association between grain yield and crown-rust reaction loci in several genetic backgrounds of Avena sativa

“…Differences within "pure line" cultivars have been found in oats by Arias and Frey (1973) and may be attributed to cumula tive mutations and/or outcrossing.…”
