Effects of Salinity on Yield and Component Characters in Canola (Brassica napus L.) Cultivars
Cultivars ‘Okapi’, ‘SLM046’, ‘Elite’, ‘Fornax’ and ‘Licord’ Brassica napus were tested for yield and component characters under different levels of salinity. The variations due to salinity levels, cultivars and cultivarxsalinity (interaction) were significant for different characters. The variable degrees of increase and decrease of regression coefficient estimate mates (curve estimation) showed the performance as influenced by different salinity levels. The performance of Brassica napus variety in plant height and days to first flowering was the best for ‘SLM046’, ‘Okapi’ ‘SLM046’ and ‘Okapi’ cultivars. ‘SLM046’ showed the best performance in days to maturity, followed by ‘Licord’ and ‘Elite’. ‘Okapi’ performed better than others regarding the increased number of seeds per plant and seed yield per plant, followed by ‘Fornax’. Considering all characters, the most tolerance ability was found in ‘SLM046’ and ‘Okapi’, against different levels of salinity.
