“…(L.) MERR.) (MUMAW & WEBER, 1957), rice (Oryza sativa L.) (JENNINGS & DE JESUS., JR., 1968) and barley (SUNESON, 1949;SUNESON & WIEBE, 1942), survival in mixtures was unrelated to yielding ability. After many generations of bulking, cultivars of rice with a tall, late growth habit increased in proportion to other cultivars (JENNINGS & AQUINO, 1968 ;JENNINGS & HERRERA, 1968).…”

“…Blends can (a) be more stable than their component lines (ALLARD, 1961 ;FREY & MALDONADO, 1967 ;SHORTER & FREY, 1979), (b) be equal to or higher yielding than their component lines (JENSEN, 1952 ;PREY & MALDONADO, 1967 ;CLAY & ALLARD, 1969), and(or) (c) have greater protection from disease than the mean of their component lines in pure stands (FREY et al, 1977 ;WOLFE & BAR-RETT, 1980) . Because of the effects of natural selection, however, changes in the genotypic composition of mixtures do occur (HARLAN & MARTINI, 1938 ;SUNESON & WIEBE, 1942 ;SUNESON, 1949;RASMUSSON et al ., 1967;KHALIFA & QUALSET, 1974; JENNINGS & DE JESUS, 1968) .…”

“…Because of the number of traits potentially involved and the complexity of interactions possible, compositional shifts within a mixture are generally unpredictable . As a result of such interactions, genotypic predominance in a mixture may not be related to yielding ability (HARLAN & MARTINI, 1938 ;SUNESON & WIEBE, 1942 ;SUNESON, 1949) or disease resistance (SUNESON, 1949), but may be related to such factors as tiller survival (LEE, 1960) and plant height (JEN-NINGS and DE JESUS, 1968 ;KHALIFA & QUALSET, 1974) .…”

Compositional stability of an oat multiline

Mixtures of genotypes are frequently unstable in composition when propagated over successive generations . This study was designed to test whether a multiline cultivar of oats (Avena sativa L .) created to control crown rust disease (caused by Puccinia coronata CDA .) would reflect differential near-isogenic line survivals when propagated under conditions of either presence or absence of rust . An oat multiline cultivar synthesized from near-isogenic lines that had different genes for resistance to crown rust was propagated under rust-free and rust epiphytotic conditions for four successive generations . In the rust-free environment, one near-isogenic line, CI 9192, which was inferior in yielding ability, was reduced significantly from 20% to 10% of the mixture, and CI 9184, which has no yield deviation from normal, increased from 20% to 38% . The other three near-isogenic lines were stable at about 20%. Also, in the rust line of descent, CI 9192 and CI 9184, respectively, decreased and increased significantly .Our results have implications with respect to seed production practices for multiline cultivars; they also raise the question of whether a multiline is stable enough in composition to be called a cultivar .

“…The dominating variety in a mixture of four barley varieties grown for several years by SUNESON & WIEBE (1942) was Atlas. It was second best in monoculture, whereas Vaughn, scoring highest in monoculture, disappeared rapidly from the mixture.…”
