anglais. The new oat variety ‘Stendes Darta’ (line No. L 28650) has been developed at the State Stende Cereals Breeding Institute. The variety is registered by the Plant Protection Service of Latvia (No. A-8 since 27.12.2004) and included in a catalogue of Plant varieties both of Latvia and EU in 2005. It is recommended for food and feed production. The oat variety is a result of hybridisation and repeated selection work. During five consecutive years (1999 – 2003), this variety gave a significantly greater yield of grain than the standard variety ‘Laima’ (+ 0.44 t haE-1, Rs0.05 = 0.21 t haE-1). On the average, line L 28650 was one to two days earlier, had higher lodging resistance (+ 2 points), and was more resistant to lose smut (on artificial infection background), oat leaf crown rust and mildew (on natural infection background) than the standard variety ‘Laima’. Oil content of the variety ‘Stendes Darta’ was high (on the average + 0.46% more than for the standard variety ‘Laima’). The oat line showed stable yields and good competition with weeds under organic farming. Evaluation of the variety ‘Stendes Darta’ during test period (1999 – 2006) showed that the variety was plastic and might provide rather suitable yields under unfavourable growing conditions as in 2006. The results of evaluation confirm that the oat variety ‘Stendes Darta’ may provide stable yields and good grain quality. Consequently, the variety is suitable for the growth in conventional and organic farming systems.

A-8 no 27.12. 2004.) un iekļauta Augu šķirņu katalogā no 2005. gada. Šķirne ir rekomendēta pārtikas un lopbarības graudu ieguvei. Šķirne izveidota hibridizācijas un vairākkārtējas izlases rezultātā. Novērojumi no 1999. līdz 2003. gadam rāda, ka jaunā šķirne ir būtiski ražīgāka nekā standartšķirne ‘Laima’ (+0.44 t haE-1, Rs0.05 = 0.21 t haE-1). Vidēji pārbaudes periodā līnija L 28650 bija par divām dienām agrīnāka, ar augstāku veldres noturību (+ 2 balles) un augstāku izturību pret putošo melnplauku, auzu lapu vainagrūsu un miltrasu. Šķirnei raksturīgs augsts tauku saturs graudos (vidēji +0.46%, salīdzinot ar šķirni ‘Laima’). Šķirne ‘Stendes Darta’ ir parādījusi stabilus ražības rādītājus un labu
