Morphobiological and agricultural traits of the tomato prospective lines

Abstract

The article presents the results of the evaluationof some tomato perspective lines developedat the Institute of Genetics, Plant Physiology and Plant Protection, Republic of Moldova. Testing on the basis of productivity, resistance to alternariosis and morphobiological characteristics of the fruit, and subsequent clusterian analysis, showed that the lines separated into three clusters differ on the basis of the fruit weight, fruit length, fruit diameter, mesocarp thickness, pericarp thickness, seminal lojes. Lineswith increased productivity –L 304, L 306, L 309 and L 310 have been identified that can be included in the breeding programs. Lines L 304, L 306, L 308, L 310 exhibited a reduced degree and frequency of attack of alternarias and may be recommended as a source of resistance to disease.
