QUANTITATIVE EVALUATION OF COMMERCIAL CANOLA CULTIVARS THROUGH G × E ANALYSIS UNDER DIFFERENT AGRO-CLIMATIC CONDITIONS

Edible oils are largest agricultural commodity in Pakistan. Brassica is the major edible oil producing crop in the country. Different Canola varieties and hybrids have been introduced by research organization and seed companies. However, there is dire need to identify Canola varieties and hybrids suitable for different agroclimatic zones of the Punjab (Pakistan). A study was conducted for performance evaluation of nine Canola varieties and hybrids in fifteen different agroclimatic locations of the Punjab (Pakistan). Data of each cultivar for seed yield, protein content and oil content were recorded from all locations. After basic statistical analysis, data were further evaluated through Additive Main Effect and Multiplicative Interaction (AMMI) biplot analysis for testing the adaptability and stability. The results interpreted that rapeseed cultivars performed better in cooler climatic region in terms of seed yield and oil content. Sandal canola, Super canola and Hyola-401 showed wider adaptability and performed well in all agroclimatic region. However, AARI Canola performed well in hot climatic region and gave good seed yield and protein content.
