Variances of Botanical Morphological Characteristics of Stylosanthes Germplasms
摘要
Abstract
To study the genetic diversity of Stylosanthes gennplasms by plant morphology and select fine germplasm, morphological characteristics of 48 Stylosanthes germplasms were observed and clustering analysis was conducted. The results indicated that, of all the 48 germplasms, 3 were subshrub, 2 were biennial herbs, and the others were perennial herbs. The types of stem growth of most gennplasms (35 ) were erective or slant ing , 5 were procumbent or spreading. Only 1 had white flowers, the other 47 had yellow flowers of different shades. Abundant morphological variation existed in Stylosanthes. Their coefficients of variation were ranked as follows: natural stem length (24.63% ), absolute stem length(22.29% ) , length/width(16.00% ), leaf width( 15.66% ) , leaf length( 12. 92% ) , 1 000-seed weight( 12. 22% ). Based on 13 morphological charac teristics , the gennplasms of Stylosanthes were clustered into two morphological types, S. Guianensis and out of S. Guianensis.关键词
