Snow damage in winter wheat (Triticum aestivum L.), which is mainly caused by snow mold diseases, is influenced by the physiological activity of the plants under the snow. This study was conducted to examine the shoot weight (SW), percentage of crown weight against the shoot weight (crown %), percentage of dry matter (DM %) and freezing tolerance (FT) by measuring median lethal ternperature (LT50) before wintering in the 1992/93 winter season, FT twice in December and in the following March, and snow mold damage in May in the 1993/94 winter season, using 45 winter wheat varieties. Moreover, we attempted to evaluate the changes in SW, DM. FT and etiolated growth (EG) in the 1992/93 winter season, using 10 representative varieties (Table 1). The correlation coefficients before wintering and 70 days after snow cover were significant for SW and DM % but not significant for FT and EG. Moreover, there was no significant correlation between the respective combinations of DM %, FT and EG. However, the relation became significant 70 days after snow cover (Table 2), mainly due to the slower decrease in physiological indicators such as FT and EG in the snow-tolerant varieties (P.I.173438, Niederndorferberg. Haunsberg, Norin 62) that were sensitive to low temperature and exhibited a higher dry matter percentage than the others (Fig.1). Correlations of FT and EG with snow mold damage were not significant before wintering, but became significant 70 days after snow cover (Fig.4, 5). On the other hand, in all the 10 varieties, DM % decreased under snow cover. As a result, a highest correlation between DM % and snow mold damage was recognized both before wintering (r=-0.618) and 70 days after snow cover (r = -0.879 * * * ). Snow-tolerant varieties were characterized by a high DM %, comparatively low FT and upright type with a crown % of around 35%, while freezing-tolerant varieties showed a high DM % and FT and a rosette type with a crown % of nearly 50% (Fig.2, 3).

Interspecific hybrids between Alstroemeria ligtu L. hybrid and A. pelegrina L. var. rosea were produced by using ovule culture. In this cross combination, viable seeds could not be obtained in the reciprocal crossings. Histological observation revealed that the hybrid embryos aborted around 28 days after pollination in the crossing of A. Iigtu hybrid × A. pelegrina var. rosea and around 35 days after pollination in the reverse crossing without appreciable development of endosperm. When ovules with placenta were transferred to 2 g/l Gelrite-solidified MS medium containing 3 % (w/v) sucrose before the embryo degeneration, plantlets were formed in the reciprocal cross combinations. However mature plants were obtained only in a cross of A. Iigtu hybrid × A. pelegrina var. rosea. The hybrid plants had intermediate characteristics between the parents, and complete haploid genomes of the both parents. Hybridity of the plants was also confirmed by DNA analysis.

We identified buckwheat plants with determinate growth habit in the populations of three Japanese lines including cultivars 'Kitawasesoba' and 'Kitayuki'. The general mor-phology of the variants from the two cultivars was normal, and the agronomic performance was broadly comparable to that of their parental lines. These variants are considered to be useful breeding materials for the improvement of Japanese buckwheat.

Mature seeds of 250 sorghum varieties were cultured to evaluate ability of callus formation and plant regeneration. Twenty germinated seeds were placed on callus induction medium and cultured for 30 days. The composition of callus induction medium was MS supplemented with 2 mg/l 2, 4-D, 30 g/l sucrose, 2 g/l Gelrite and pH was adjusted to 6.0 before autocraving. The composition of callus maintenance medium was the same as callus induction medium except that the concentration of 2, 4-D was reduced to 1 mg/l and the calli were cultured for 30 days. The composition of plant regeneration was the same as callus induction medium except that 2, 4-D was omitted. After 30 days of culture on the regeneration medium, plant regeneration was evaluated. In this culture system, most varieties formed compact yellowish calli. Type of plant regeneration was organogenesis and distinct somatic embryogenesis was not observed. In many cases only root formation was observed. Five varieties showed relatively high ability of plant regeneration. They were CK602, CKW5809, PE932 203, PE954 068 and PE954 110. Among the variety groups, Kafir group varieties showed relatively high ability of callus formation and plant regeneration. These five varieties and Kafir group varieties may be useful for iu vitro study of sorghum which requires plant regeneration.
