Evaluating pasture forage plant breeding achievements: a review

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 6, Page 1146-1220, December 2025.
ABSTRACT Forage plant breeding aims to deliver cultivars that increase on‐farm productivity through improved seasonal and annual yield, persistence of yield in perennials, and nutritive and feeding value. Breeding is generally undertaken in highly controlled field trials with individual plants or rows.
