Выявление корреляционных взаимосвяз

Выявление корреляционных взаимосвязей между признаками или индексами широко применяется в решении различных селекционных задач. Впервые В.А. Драгавцевым была установлена значительная изменчивость генетических корреляций главных признаков, определяющих урожайность, в зависимости от резко отличающихся условий среды. Для ряда количественных признаков и индексов отмечено противоположное направление генетических корреляций, с одной стороны и средовых корреляций - с другой, при смене конкретного лимитирующего фактора. На различных сельскохозяйственных растениях (пшеница, горох, нут, подсолнечник) наблюдали разнонаправленность генетических и средовых корреляций, которая открывает возможность увеличения в несколько раз эффективности отбора по хозяйственно полезным признакам в процессе селекции.

Identifying correlation relationships between traits or indexes are widely used in solving various selection tasks. First V.a. Dragavcevym was installed a large variability of genetic correlations of the main signs that determine the yield dramatically different depending on environmental conditions. For a number of quantitative attributes and indexes observed the opposite direction genetic correlations, on the one hand and environmental correlations, when changing a specific limitation factor. On various crops (wheat, peas, chickpeas, sunflower) watched the raznonapravlennost′ genetic and environmental correlations, which opens up the possibility of an increase in screening effectiveness several times economically useful traits in the breeding process.

Identification of correlations between the features or indices are widely used in solving various problems of selection. For the first time, VA Dragavtsevym was established considerable variability of genetic correlations main attributes that determine the yield, depending on the environmental conditions differ sharply. For a number of quantitative characters and indices mentioned opposite direction genetic correlations, on the one hand and environmental correlations - on the other hand, when changing the specific limiting factor. At various agricultural crops (wheat, peas, chickpeas, sunflower) multidirectional genetic and environmental correlations, which opens the possibility to increase several times the effectiveness of selection for economically useful traits for breeding purposes.

Identifying correlation relationships between signs or indices are widely used in the various plants. For the first time in a year.Драгавцевым was installed a large variability genetic correlations main signs, determining yield, depending on dramatically different environmental conditions.For a number of quantitative indicators and indices was observed the opposite direction genetic correlations, on the one hand and inspecting correlations - on the other, when you change a specific limitation factor.The various agricultural plants (wheat, peas, distinct, sunflower) have seen organomodifying genetic correlation and eliminations,Which opens up the possibility of an increase in efficiency several times selection of household useful breeding grounds in the process.
