Dlya analiza ispol'zovali zerno sortov Povolzhskaya Niva, Kinel'skaya 8 i Konstantinovskaya urozhaya 2013-2015 gg. Dlya polucheniya variantov opyta k nepovrezhdennomu zernu v opredelennom vesovom otnoshenii dobavlyali povrezhdennoe zerno. V stat'e privoditsya issledovanie vliyaniya razlichnoy stepeni povrezhdennosti zerna ozimoy pshenicy vrednoy cherepashkoy (Eurygaster integriceps Put.) i pshenichnym tripsom (Haplothrips tritici Kurd.) sortov Povolzhskaya Niva (Velyutinum), Kinel'skaya 8 (Lyutescens) i Kon-stantinovskaya (Eritrospermum) na tehnologicheskie pokazateli sostava zerna – kleykoviny. Naibolee chuvstvi-telen k povrezhdeniyu zerna klopom cherepashkoy (Eurygaster integriceps Put.) okazalsya sort Povolzhskaya Niva, s poterey kleykoviny ot 1,2 do 4,6% na variantah s povrezhdeniem zerna ot 3 do 10%. Sorta Konstantinovskaya i Kinel'skaya 8 otnosili k sredne ustoychivym, snizhenie kleykoviny sostavlyalo 0,4-3,2%. Naibolee chuvstvitelen k povrezhdeniyu zerna pshenichnym tripsom sort Povolzhskaya Niva (raznovidnost' Velyutinum) s poterey kleykoviny ot 0,5 do 1,6% na variantah s povrezhdeniem zerna ot 3 do 10%. Sorta Konstantinovskaya i Kinel'skaya 8 otnosilis' k ustoychivym, snizhenie soderzhaniya kleykoviny sostavlyalo 0-1,2%. Maksimal'noe soderzhanie kleykoviny otmecheno v nepovrezhdennom zerne sorta Konstantinovskaya (35,2%). Nailuchshiy pokazatel' IDK nablyudalsya u nepovrezhdennyh zeren i povrezhdennyh na 3% sorta Kinel'skaya 8 (79-86 ed.). Poluchennye rezul'taty mogut byt' ispol'zovannye v selekcionnoy rabote s cel'yu povysheniya geneticheskogo potenciala suschestvuyuschih sortov, obladayuschih v chastnosti ustoychivost'yu k klopu cherepashke. Eto pozvolit povysit' effektivnost' ispol'zovaniya naibolee kachestvennyh i ustoychivyh sortov v proizvodstvennyh usloviyah, chto v svoyu ochered', privedet k snizheniyu poter' kolichestva i kachestva zerna kak v polevyh usloviyah, tak pri hranenii.
