SKYBOLT is an exciting new winter feed wheat cultivar bred by Limagrain UK and further developed by PGG Wrightson Grain (PGW Grain). In the past six seasons in internal and FAR CPT trials, SKYBOLT has produced consistently high yields across all grain growing environments. It has been in CPT 2 trials for three seasons where it has been a consistent performer in Canterbury, Southland and the lower North Island. It has a good disease package and produces an intermediate hard/soft grain with high kernel weights and good test weights.

From autumn plantings, SKYBOLT is an intermediate maturing cultivar. However, it should not be planted after the end of June in areas with mild winters as its high vernalisation requirement may result in excessively delayed heading. From the PGW Grain 2023/24 sowing date and rate trial, an average yield decrease of 5.0-7.2 t/ha was observed from sowing after June.
SKYBOLT has moderate tillering capacity and a tight V-shaped tillering habit. Target plant populations should be slightly above the ranges on the Cereal Seed Sowing Rate Page. The 2023/24 PGW Grain sowing date and rate trial confirmed that in high fertility/April sowings a target plant population of 125-150 plants/m² is optimal. In medium yielding sowings (such as May) it should be increased to 150-200 plants/m² and in lower yielding sowings (such as June) further increased to 200-225 plants/m².
SKYBOLT has good resistance to most cereal diseases in New Zealand, especially stripe rust and powdery mildew. Considering this disease profile and fungicide trials conducted by PGW Grain the last three seasons, a low to moderate fungicide programme is recommended. SKYBOLT has consistently produced high untreated yields of over 12.0 t/ha and average fungicide response of 0.5-1.5 t/ha. It has been entered into PGW Grain fungicide trials for the 2025/26 season to provide further information. Please contact your local PGW Representative for site specific recommendations.
