Variation and correlations of lodging related characters in sesame germplasms

Analysis was made on the variation and correlation among the major agronomic characters related to lodging in 108 collections of sesame germplasm. Plant height ranged from 49cm to 120cm being 95cm in mean, and of which were 17 varieties belower than 80cm. The mean of major characters were 59cm in length of capsules bearing stem, 11.3mm in stem diameter, 7.9cm in 3rd internode length, 12.4mm in root diameter, 13cm in primary root length and 61° in root distributive angle. There were 11 varieties of root diameter above 14mm, 24 varieties of root distributive angle above 70°, 13 varieties of lodging degree from zero to one, respectively. A highly significant positive correlation were shown between plant height and length of capsules bearing stem, between stem and root diameter, between the number of adventitious roots and root distributive angle. Lodging degree was highly positive correlation associated with plant height and length of capsules bearing stem, but which showed negative correlation with stem and root diameter, primary root length, the number of adventitious roots and root distributive angle.
