Title:
 Analysis of selected grasspea mutants by generalized linear model

Language: English

Keywords:
generalized linear model
grasspea mutants
logistic model

Summary:
Grasspea (Lathyrus sativus L.) is characterized by low habitat requirements, high content of protein and favorable composition of fatty acid in seed. Simultaneously, grasspea posses a lot of unfavorable traits from agronomy point of view. Essential is to modify this plant on the genetic level for example through mutation induction. The object of investigation constituted three gras-spea mutants and their initial cultivar Derek, analyzed for eight characters in Experiment Station in Cerekwica. The field trial was conducted according to method of randomized block design with three replication. All mutants were obtained after grain irradiation of cultivar Derek with laser light and two chemomutagen treatment: N-nitroso-N-methylurea (MNU) and sodium azide (NaN3). The aim of the work was to compare the variety Derek with its mutants with respect to two selected traits: the number of pods per plant and the number of branches per plant. Both considered traits are treated as discrete, so in the analysis the logistic model which belongs to the class of generalized linear models was applied.
