Winter Wheat Varieties

Experiments in the Canberra phytotron with several European winter wheat varieties, especially cv. Templar, have shown that their need for vernalisation at low temperature can be replaced entirely by growth in short days at 21/16°C for the same period. In fact, although wheat is usually classified as a long day plant, inflorescence initiation at 21/16°C in unvernalised plants was twice as rapid in 8 h photoperiods as in 16 h ones. Short day induction was fastest in photoperiods of less than 12 h and was relatively insensitive to irradiance. Inflorescence development following initiation was faster the longer the photoperiod. At high irradiance, anthesis eventually occurred in 8 h days, but not at lower irradiance. These wheats are therefore short-long day plants, and may appear to be indifferent to daylength if only their time to anthesis is observed. Although short days can replace low temperatures, there are several important differences in their modes of action, and short day induction is better not referred to as short day vernalisation. Vernalisation of developing grains in the ear was more effective in long days.

In 1998 and 1999, 52 winter wheat varieties and breeding lines originated from ten European countries were tested for their reaction to leaf rust, the inoculum was a mixture of races UN3-61SaBa and UN13-77SaBa. Twenty six varieties and lines stayed in the same group (susceptible, moderately susceptible, moderate, moderately resista nt) in both years, with the majority being moderately resistant. Of the Czech varieties Asta, Rexia and VIada stayed in the same group in both years. Some varieties moved from one group in 1998 to another in 1999. Some of the moderately resistant varieties and lines (Hereward, WW2568, P8634, Trakos, WW251 0, Asset, WW2564) showed a hypersensitive reaction (chlorosis, necrosis). There were differences in the number of diseased plants between groups with a different reaction to leaf rust mainly at the beginning of the epidemic

Winter Wheat Varieties

A total of 124 recent winter wheat accessions of European origin were screened for coleoptile length and plant height. Most of the accessions (74.2%) possessed a coleoptile length ranging between 5.00 and 7.00 cm. The German varieties Ebi, Pegassos, Flair without <em>Rht </em>genes had a coleoptile length of 9.08, 9.43, 9.56 cm and a plant height of 97, 95 and 98 cm, respectively. The Serbian variety Pobeda possessing <em>Rht8 </em>had a coleoptile length of 9.14 cm and a plant height of 71 cm. The varieties possessing <em>Rht-B1b</em>, <em>Rht-D1b </em>had a significantly shorter mean coleoptile length (5.45 cm) and mean plant height (84.5 cm) than the varieties without <em>Rht </em>genes (7.41 and 99.6 cm). The correlation between coleoptile length and plant height was medium (r = 0.613, <em>p </em>&lt; 0.01) when the calculation excluded the varieties from Central and Southern Europe. The similar plant height, but not coleoptile length of the varieties possessing different dwarfing factors enables development of novel varieties with desirable height and coleoptile length from the European winter wheat germplasm.

Winter Wheat Varieties

Owing to the significant differences in the adaptability of state-registered varieties, those which can adapt well to the local conditions should be given preference. There are several high-yielding varieties available in Hungary with excellent agronomic properties, good adaptability and satisfactory baking quality. This study was conducted to analyse the adaptability of 34 state-registered winter wheat varieties tested in the small plot trials of the National Institute for Agricultural Quality Control (NIAQC) at 5–9 locations between 1994 and 1997 based on their gluten quantity and farinographic index. For the comparison of the varieties the evaluation method of Eberhart and Russell (1966) was applied as modified by Bedő and Balla (1977). The qualitative stability and adaptability values of the varieties differ from the adaptability and stability values calculated from the grain yields. Some winter wheat varieties have good qualitative adaptability and stability, while others have special adaptability and poor qualitative stability, but the majority of the varieties do not belong to these groups.
