АГРОТЕХНИЧЕСКАЯ И БИОЛОГИЧЕСКАЯ ЦЕННОСТЬ ЧИНЫ ПОСЕВНОЙ (LATHYRUS SATIVUS L.), КАК ПИЩЕВОЙ И КОРМОВОЙ КУЛЬТУРЫ (ОБЗОР)

Статья посвящена обзору направлений использования одной из древнейших окультуренных растений – чины посевной. Чина посевная традиционно выращивается на пищевые цели в южных странах с аридным климатом или в засушливый период. В силу своих биологических особенностей чина посевная способна занять в сельском хозяйстве Российской Федерации агроэкологическую нишу на территориях с недостаточным увлажнением между агрономическими ареалами выращивания гороха и нута.

Combination ability of corn lines and genetic control of morphometric parameters

The article presents the results of studying the combination ability of new dihaploid maize lines created by diploidization of haploid plants obtained using a haploinducer line. The experiment involved simple hybrids (30 combinations) obtained according to the complete diallel scheme of 6 homozygous lines. The eff ects of GCA and variance of SCA lines, as well as the components of genetic variance in terms of the main morphometric parameters of the plant (stem length, ear height, panicle length, stem diameter, plant leaf surface area) were revealed.

Correlation analysis of traits characterizing the yield and product quality of representatives of the genus Allium (subgenus Cepa)

In the conditions of the Moscow region, 10 samples of representatives of the genus Allium L. were studied, including: A. altaicum Pall., A. fi stulosum L., A. galanthum Kar. & Kir., A. oschaninii O. Fedtsch., A. pskemense B. Fedtsch from the section Cepa (Mill.) Prokh.; A. altyncolicum N. Friesen, A. ledebourianumSchult. & Schult. f., A. oliganthum Kar. & Kir., A. schoenoprasum L. from the section Schoenoprasum Dum.; A. komarovianum Vved. from the section Sacculiferum P. P. Gritz.

Economic and Biological Characteristics of the New Generation of Winter Wheat Varieties

The aim of the work is a comparative assessment of economic and biological characteristics (yield and crop structure elements, winter hardiness, morphological structure of the stem) of the new generation of winter soft wheat varieties. The studies were conducted in 2017–2019 in the conditions of the South-East of the Central black earth region. The object of research is winter wheat, represented by varieties Steppe 135, Basalt, Chernozem 115, Chernozem 130 and Basalt 2, created at different times of selection work.
