PECULIARITIES OF YIELD FORMATION IN PEA OF VARIOUS MORPHOTYPES UNDER CONDITIONS OF FOREST-STEPPE AREAS NEAR THE OB RIVER
There were revealed the varieties and breeding lines of pea most adapted to the conditions of forest-steppe areas near the Ob River. There were observed the most high-producing specimens of various morphotypes: leafless tall TM-05-148, leafless baby garden Rus and TM-06-208, chameleon TM-03-34 and TM-06-259, leaf tall TM-04-77, leaf baby garden TM-05-1330 and Tyumenets. The indices of productive stem-stand and one-plant-grain mass in the selected specimens were determined to be high. It was established that pea productivity was conditioned by the increase in both the number of kernels and grain size.
