Résumé en langage clair

In 2022, a prolonged, moist spring delayed the fruit development and maturation for two weeks. Due to the high crop load and summer heat waves in 2021, returning bloom and crop load in 2022 was low. Rootstock effect was significant in return bloom, canopy spread, TCSA and yield (Annex Table 1). The trend in TCSA was consistent with 2021, with NZ#5 > G.935 > G.969 > NZ#1 > G.4814 > G.41 > G.11 > Bud 10 > NZ#2 > G.214 > M.26 > M.9T337 (Annex Fig. 1). G.935 led to the highest yield, significantly higher than M.9T337, M.26 and G.214. M.26. had the lowest returning bloom abundance, crop load and fruit weight.
