Abstract

The validity of Kosambi's formula to estimate map lengths is tested with Jodon's (1940) data on the segregation of four factors, gu, as, v and cl, located in a single chromosome in rice. The data were found to agree very well with the formula. The method of testing is briefly described. A map of the chromosome in centimorgans, is given on the basis of the estimates made by applying the formula. The situation regarding the factor fl is discussed.
