Model for breeding of high productive garden pea varieties

Slavka Kalapchieva

Abstract: A linear equation of regression has been used for establishment of the effect of qualitative characters on the productivity of green grain in garden pea and for development of a model for breeding work. The obtained results demonstrated that the greatest effect on productivity of green grain have the productive nodes of the plants and pod length followed by the average pod number per fruit stalk and knot number to the first pod. The productivity that is mathematically proven depends only on the plant height, number of productivity nodes and pod length.
