ASSESSING THE BREEDING VALUE OF NINE SPRING FIELD PEA (PISUMSATIVUML.) CULTIVARS

摘要

The investigation was performed during the period 2007-2009 in the second experimental field of institute of Forage Crops, Pleven. Were studies follow varieties: Kristal, Prcardi, Amilie, Dru/ba, Kerpo, Usatii 90, Rezonator, Harkovskii atalon. The variety Pleven 4 was used as a standard. According to the obtained experimental data the varieties could be classified to different groups on earliness. Early are Picardi, Amitic and Harkovskii atalonn with earliness coefficient 1.00, mid early is Kcrpo 1.38 - 1.57 and late varieties Kristal, Druzba, Pleven 4, Usatii 90, Rezonator. Harkovskii atalon is characterized with high lodging resistance only 28.61% from plants are lodging susceptible and it could be including in the future hybridization as donor ofessential characters. With highest seed yield are Harkovskii atalonn (207.17 kg x da~(-1)), Kerpo (206.08 kg x da~(-1)) and Usatii 90 (203.33 kg x da~(-1)) what opportunity to be included in breeding programs for high yield varieties.
