Correlation studies in tuberose (Polianthes tuberosa L.)

Correlation analysis carried out among eight tuberose single genotypes and six tuberose double genotypes at Indian Institute of Horticultural Research, Bangalore during 2001-02 for 10 quantitative characters. Analysis of variances in case of single genotypes revealed loose flower yield exhibiting positively significant response at genotypic and phenotypic levels with spike length, number of flower per spike, flower length, flower diameter, hundred flower weight and spike weight Number of flowers per spike showed significant positive correlation with loose flower yield, spike length, rachis length at both levels. In double genotypes, spike yield showed positive and significant correlation with number of leaves per plant, rachis length, and flower length and flower diameter. Rachis length also shoed positively significant correlation with plant height, spike length, flower length, spike weight and spike yield at both genotypic and phenotypic levels
