Title

EVALUATION OF YIELD AND YIELD COMPONENT RAPESEED CULTIVARS IN ARAK REGION

Pages

  83-92

Abstract

 This survey was done to assessment YIELD and YIELD component of fall RAPESEED cultivars (Brassica napus) in climatic conditions of Arak was conducted cropping season 2004-2005. The experiments were arrange in Split Plot design and were compared in a CRBD with three replications. In this design, PLANTING DATE treatment assumed as the main factor in two levels (usual PLANTING DATE and delayed PLANTING DATEs) and autumn RAPESEED cultivars in eleven levels were assumed as subplot. The considered cultivars in this research were Dexter, Celsius, ARC91004, Sahara, ARC5, Orient, Sinotra, Talent, Talaye, ARC2 Geronima and Talaye variety was considered as control. The results of experiments showed that in usual PLANTING DATE condition and delayed PLANTING DATEs cultivars in adjectives like the number of pods in plant, number of grains per pod, the weight of thousand seeds and seed YIELD had significant difference in level %1 probability. The highest YIELD of seed was related to Talaye variety with average 3463. 5 kg/ha and the least YIELD rate of seed was related to Geronima variety with average 2651.8 kg/ha. Usual PLANTING DATE in terms of YIELD performance of seed, Talaye variety has been the best, and after it, also the cultivars as Talent, Sahara and Celsius had the highest level respectively. In terms of seed thousand weight, Talaye and Talent variety, and in terms of the number of seed in pod, ARC2 and Talaye variety in usual PLANTING DATE, the number of pods in plant Talaye and Celsius variety in usual PLANTING DATE were better than others.
