title: Testing uniformity of mutants of the Lathyrus sativus L. (grasspea) using Bennet's method.
abstract: In this paper interest is focused on uniformity of individual mutants. Because before the registration of a new variety the criteria for DUS (distinctness, uniformity and stability) are checked, so you should also check whether the mutant meets them. The aim of created mutants, in many genetic experiments, is to expand variation of the initial material. This is achieved through use of the mutagen or combination of mutagens on different stages of plants growth. The experimenter should choose some of obtained mutants (for example these which showed better property as regards the same trait). Calculations were done on the basis of results of test with variety Krab of the Lathyrus sativus L. (grasspea) species and 17 mutants getting from this variety. Uniformity was checked with the use of the Bennett's method which is based on testing of equality of coefficients of variation. After analysis the mutants with codes K3, K37, K63 and K64 were detected as uniform at the same level as variety Krab.
