Correlation Coefficients and Path - Analysis of Various Characteristics of Dihaploids derived from Tobacco (Nicotiana tabacco L.)Anther Culture in vitro

담배 약에서 유기된 반수체 배가계통의 변이, 상관 및 경로분석

Dihaploid lines were derived from the anthers of the F, of single cross, "Va 115" x"SC 72" (Nicotiana tabacum L.). The path-analysis, correlation coefficient, and variation of characteristics among dihaploid families were evaluated. Dihaploid lines displayed much greater variation than their parents. The genetic correlation coefficient between yield and total alkaloids of dihaploids was significantly lower than that of conventional varieties and lines. In path-analysis which relates yield components to yield, number of leaves harvested and leaf width had a direct effect on yield. a direct effect on yield.
