ABSTRACT
Single plant yield was highly and positively correlated with number of capsules in primary spike, number of spikes per plant, relative water content and proline content at both genotypic and phenotypic levels. So, simultaneous selection for number of capsules in primary spike and number of spikes per plant will increase the single plant yield automatically. High positive direct effect on single plant yield was shown by number of capsules in primary spike, length of the primary spike, number of spikes per plant, relative water content and proline content. The present investigation revealed that, the improvement could be achieved only through number of capsules in primary spike irrespective of the character chosen to increase the yield under selection.
Key words :
Castor, Correlation, Genotypes, Membrane injury index, Proline.
