Identifying Pollen Incompatibility Groups in California Almond Cultivars
Six cross-incompatibility groups, which contain most of commercially important California almond cultivars [Prunus dulcis (Mill.) D.A. Webb, syn. Prunus amygdalus Batch], and their self-incompatibility (S) allele genotypes are identified. Incompatibility groups include `Mission' (S a S b ), `No...

Summary: | Six cross-incompatibility groups, which contain most of commercially important California almond cultivars
[Prunus dulcis
(Mill.) D.A. Webb, syn.
Prunus amygdalus
Batch], and their self-incompatibility (S) allele genotypes are identified. Incompatibility groups include `Mission' (S
a
S
b
), `Nonpareil' (S
c
S
d
), and the four groups resulting from the `Mission' × `Nonpareil' cross: (S
a
S
c
), (S
a
S
d
), (S
b
S
c
), and (S
b
S
d
), as represented by `Thompson', `Carmel', `Merced' and `Monterey', respectively. All seedlings from the `Mission' × `Nonpareil' cross were compatible with both parents, a result indicating that these two cultivars have no alleles in common. Crossing studies support a full-sib relationship for these progeny groups and the origin of both parents from common germplasm. Cultivars in these six groups account for ≈ 93% of present California production, a result demonstrating a limited genetic base for this vegetatively propagated tree crop. |
