The aim of this study was to determine the most sensitive growth stage of the common millet (Panicum miliaceum L.) to frost temperatures, and to evaluate differences in frost resistance among varieties. A modified field-laboratory approach method was used for the evaluation of four varieties. The lethal temperature (LT 50) was determined for all variants. The critical time for lethal temperature (LT 50) was determined in the stage of two secondary leaves. Millet is the most sensitive to frost temperature from the stage of two secondary leaves to the beginning of tillering. Differences among sensitivity of growth stages are influenced by environmental conditions. The lethal temperature of the common millet ranged from –1.5 to –4.1°C, depending on stage of development and growth conditions. Differences among varieties were significant in field conditions. Variety 'Hanacka Mana' was the most resistant from chosen varieties in field.

Key words: common millet, Panicum miliaceum, frost resistance, variety evaluation

Raziskava odpornosti sort navadnega prosa (Panicum miliaceum L.) na slano

Namen raziskave je bil določiti stadij razvoja, ki je najbolj občutljiv na nizke temperature (na slano) in razlike med sortami navadnega prosa (Panicum miliaceum L.). Uporabljen je modificirani pristop, ki je vključeval poljske razmere in laboratorij, analizirane pa so bile štiri sorte. Letalna temperatura (LT 50) je bila določena za vse variante. Kritični čas letalne temperature (LT 50) je bil določen v fazi dveh sekundarnih listov. Proso je najbolj občutljivo na slano od faze drugega sekundarnega lista do začetka razraščanja. Na razlike med občutljivostjo posameznih faz rasti vplivajo okoljske razmere. Letalna temperatura navadnega prosa se giblje od -1,5 do -4.1°C, odvisno od faze razvoja in rastnih razmer. Razlike med sortami v poljskih razmerah so bile signifikantne. Najbolj odporna je bila sorta 'Hanacka Mana'.

Ključne besede: Navadno proso, Panicum miliaceum, odpornost na slano, vrednotenje sort
