CHARACTER OF OF THE CONJUGATION OF CHROMOSOMES IN ANTHER MOTHER CELLS OF INTERSPECIFIC TOMATO F1 HYBRIDS

abstract 0651101011 issue 65 pp. 125 – 134 31.01.2011 ru 2210
The analysis of frequency and distribution of chiasma of interspecific tomato F1 hybrids at meiosis prophase I was given. The character of synapsis in anther mother cells of interspecific tomato F1 hybrids was determined; the number of distal and interstitial chiasmata was calculated. The samples, recommended for their inclusion into the selection process as the inducer of genetic variability were chosen

INHERITANCE OF MORPHOLOGICAL CHARACTERISTICS FROM INTERSPECIFIC TOMATO F1 HYBRIDS

abstract 0651101010 issue 65 pp. 114 – 124 31.01.2011 ru 1152
The detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability
