Skirtingos geografinės kilmės miškinio pelėžirnio (Lathyrus sylvestris L.) sėklų produktyvumo parametrų analizė

Abstract

Analysis of seed productivity parameters of different geographical origins flat pea (Lathyrus sylvestris L.) cenopopulations have been dune in 2012-2013. The resistance to downy mildew (Peronospora sp.) influenced morphological and productivity parameters of flat pea. The greatest stem height, formed seed per pod and seed productivity had cenopopulations with biggest resistance to downy mildew. Positive correlations between resistance to downy mildew and pod number (r = 0,6967), resistance and formed seed per pod (r = 0,5862) was estimated. Positive correlations between plant height and number of pods (r = 0,7539) were established. The most resistance to downy mildew and productive cenopopuliations were origin from West and Norf – West part of Lithuania. Most stabile, genetically determined reproductive features of L. sylvestris were the number of formed seed (ovules) per pod (12,2-12,7 pct.), most variable – number of brunches, number of pods and seed yield.
