Abstract

Canola's (Brassica napus L.) seed yield (SY) is a function of plant number per square meter (PNSM), POD NUMBER per plant (PNP), SEED NUMBER per pod (SNP) and SEED WEIGHT (SW). To quantify the role of yield components in determining SY, 12 field experiments were conducted at Agricultural Research Station of Gonbad, during 2000-7. The results showed that in both groups of open pollinate (OP) and hybrid genotypes, SY were not affected by PNSM and SW. With a density of 100 plant per square meter, SY was different from 100 to 4800 kg/ha. Although there were positive and significant relationships between SY and PNP, and between SY and SNP, but when 3 components of PNSM, PNP and SNP were combined in SEED NUMBER per square meter (SNSM), there was a significant relationship between SY and SNSM. With an each number increase in SNSM, SY of OP and hybrid genotypes increased 0.02 kg/ha, respectively, showing the similar and positive reaction of SY in both groups of genotypes to increase in PNSM. The existence of very strong relationship between SY and SNSM in different genotypes and environmental conditions showed that SNSM was the main components of canola SY, so canola SY can be increased by increasing SNSM.
