Kernel number per spike stability of wheat genotypes grown on meliorated soil (solonetz)

Abstract

In this work was analyzed number of grains per spike stability for 11 bread wheat varieties, on halomorphic soil, solonetz type, in Banat. Stability have been followed in two vegetation periods on null control, and two melioration levels of 25 t/ha, and 50 t/ha phosphor-gypsum. Genotype by environment interaction was quantified using AMMI model. According the results, wheat varietes in the exam reacted differently to different levels of melioration, depending not only on genotype, but also on environmental conditions.

U radu je analizirana stabilnost broja zrna po klasu 11 genotipova pšenice, na halomorfnom zemljištu, tipa solonjec u Banatu. Stabilnost je praćena u dve vegetacione sezone, na kontroli i dva nivoa popravke zemljišta fosfogipsom. Interakcija genotip/ spoljna sredina procenjena je AMMI modelom. Zapažena je različita reakcija sorti pšenice na nivo popravke zemljišta, u odnosu na svaki tretman i vegetacionu sezonu.
