This study was aimed to assess drought tolerance in twelve tomato populations collected in the territory of Serbia and to investigate relationships and repeatability among sixteen drought tolerance indices. Drought tolerance was estimated at the stage of intensive vegetative growth, on the basis of dry weight yield determined at optimal and limited irrigation (volumetric soil water content of 35.0 and 20.9%, respectively). The trial was set in pots placed in the greenhouse. Significant differences were found among populations in terms of all considered parameters; populations G125, G105 and G104 performed well in both irrigation regimes. High repeatability was found between the selection indices TOL and SSPI, STI and GMP, DWdr and YI, and among SI, SSI, RDI, SDI and RD. Principal component analysis allows simultaneous evaluation of populations and interpretation of interrelationships among the indices; it may be recommended as a method of choice for data analysis in further studies on ...drought tolerance in tomato.
Ogled je postavljen sa ciljem procene tolerantnosti na sušu dvanaest populacija paradajza prikupljenih na teritoriji Srbije, kao i sa ciljem ispitivanja šesnaest selekcionih indeksa koji se koriste za tu procenu. Tolerantnost na sušu je utvrđena u fazi intenzivnog vegetativnog rasta, na osnovu prinosa suve materije izmerenog u uslovima optimalne i ograničene obezbeđenosti vodom (zapreminski procenat sadržaja vlage u zemljištu 35,0% odnosno 20,9%). Ogled je postavljen u saksijama smeštenim u staklenik. Konstatovane su značajne razlike među populacijama u pogledu svih izučavanih parametara; za populacije G125, G105 i G104 je utvrđen visok prinos suve materije u oba režima zalivanja. Visok stepen ponovljivosti je zabeležen za TOL i SSPI, STI i GMP, DWdr i YI, kao i između SI, SSI, RDI, SDI i RD. Metod glavnih komponenata je omogućio istovremeno vrednovanje populacija i interpretaciju veza između indeksa. Zato može da se preporuči za analizu podataka u budućim istraživanjima koja se tiču t...olerantnosti paradajza na sušu.
