Natural selection for blue and white aleurone color in barley, with yield and agronomic data
Year: 1958
Type: dissertation
Abstract: This study was conducted to compare the performance of blue and white aleurone seed at different locations in the state.No differences were found in plant height, date of heading, tillering, percent protein or seed weight.Blue aleurone seed averaged higher in percent skinning when threshed, Test weight differences were small but in most cases favored the blue seed, which may have resulted from the higher skinning percent of the blue seed.Yield comparisons of blue and white isogenic lines showed no Significance due to, seed color; however, yearly differences did exist, but not significantly.Blue and white seed grown in 50-50 mixtures showed a natural selection against blue seed when grown at Moccasin for five years.Five bulked hybrids were grown at two locations.through various generations to determine natural selection of seed color.Two of the hybrids did not fit their expected ratios at Bozeman or Moccasin.Two had good fits at both locations.One performed as expected at Moccasin but not at Bozeman.When all hybrids were averaged on a yearly basis two significant losses in percent blue seed were obtained at At Moccasin a in 1955 and a Bozeman, one in 1953 and the other in 1957 significant loss in blue seed was recorded gain in 1957.No natural selection trends could be detected when the five bulked hybrids were grown at five locations in the state for two years.
