Environmental suitability of VNIISSOK'S area for vegetable marrow breeding program for adaptability and productivity

The significant variation has been shown in parameters of VNIISSOK's environmental area that have been tested for the several last years. This can be used for breeding program in vegetable marrow for plant adaptability. To perform the mass selection on at the effective level, the genotype testing on stability should be carried on for not less than 4 years. As result, the typicalness of environment has been high for most years of the study. To speed up the plant potentiality test there should be used the environmental area of the much higher productivity.
