Spike stability parameters in wheat grown on solonetz soil

Abstract

Phenotypic variability of the number and grain weight per spike, as well as the spike length of wheat varieties NSR-5, Evropa 90 and Pobeda creation of the Institute of Field and Vegetable Crops in Novi Sad was studied. The trial was conducted at the village Kumane locality in Banat on solonetz soil. Control and two levels of amelioration (25t/ha and 50t/ha of phosphor gypsum) in three vegetation periods were followed. The variety Evropa 90 exhibited maximal values of all examined spike traits in all years of study. Significant value of the first PCA was denoted for the grain number and the grain weight per spike, using AMMI model.
