Description
As is well known, orchardgrass seeds do not mature and ripen uniformly and early maturing seeds frequently shatter before late developing ones mature. Consequently, in seed crops, high losses can either be due to early'harvesting resulting in an excess of light seeds, or to delayed harvesting resulting in seed shattering. Several agronomic strategies are used by seed producers to minimize seed losses, but the additional costs involved have limited their adoption. Previous papers (Falcinelli et al., 1983 ; 1984) have reported that many populations of D. glomerata from Southern Italy and some populations from Central Italy showed no seed shattering even at the full maturity stage, seed shattering being delayed until late autumn (Falcinelli et al., 1985). Seed growers could benefit if seed-shattering resistance could be transferred to shattering varieties. This paper refers to breeding work done with the aim of introducing shattering resistance in the American variety Hallmark.

Breeding in Progress for Seed Retention in Orchardgrass (Dactylis glomereata L.)
As is well known, orchardgrass seeds do not mature and ripen uniformly and early maturing seeds frequently shatter before late developing ones mature. Consequently, in seed crops, high losses can either be due to early'harvesting resulting in an excess of light seeds, or to delayed harvesting resulting in seed shattering. Several agronomic strategies are used by seed producers to minimize seed losses, but the additional costs involved have limited their adoption. Previous papers (Falcinelli et al., 1983 ; 1984) have reported that many populations of D. glomerata from Southern Italy and some populations from Central Italy showed no seed shattering even at the full maturity stage, seed shattering being delayed until late autumn (Falcinelli et al., 1985). Seed growers could benefit if seed-shattering resistance could be transferred to shattering varieties. This paper refers to breeding work done with the aim of introducing shattering resistance in the American variety Hallmark.
