Purpose. Morphological and organoleptic evaluation of oyster mushroom strains for selection of highly productive cultivars assortment with valuable consumer properties for winter and summer cultivation and suitability for sale in fresh or processed form were investigated.Methods. The scheme of the experiment included six strains of oyster mushrooms belonging to two species: Pleurotus ostreatus (5 strains: 2301, Z, 2316, 2456, 431) and P. pulmonarius (2314). Laboratory, laboratory-industrial and statistical methods are used.Results. The dynamics of agrochemical parameters of substrates obtained by the method of aerobic fermentation in the high layer proved their optimality according to the main criteria and compliance to regulatory documentation. The biological efficiency of the strains was in the range of 40–78.9%. The highest weight of clusters was found in the “summer” strain 431 (430.7 g). The highest weight of the fruiting body was determined for the strain 2301 (15.2 g), the lowest – for the 2456 (3.3 g).Conclusions. The values of biological efficiency of strains was determined. The highest average values for the first flush of fruiting had strains 2316 (78.9%) from the “winter” group (A) and 431 (78.4%) from the “summer” group  (B). According to the results of statistical analysis, significant differences were revealed between the studied strains in the main morphological indicators of clusters. It was found that the mass of clusters of «winter» cultivars is much less dependent on the strain type (220.8–273.4 g) than that of «summer» cultivars (83.4–430.7 g). The index of the asymmetry coefficient of the cluster, which can be useful for calculating the required container sizes was proposed. It was determined that the morphological features of fruiting bodies had significant differences in all studied parameters.  In particular, the A group strains differed in size and weight. It was proposed the index of weight loss of the crop coefficient, which shows the ratio between the cap and stipe of the fruiting body and make it possible to predict the amount of mushroom raw material that will be sold in the form of caps, and the amount of raw material that can be processed into minced mushroom, powder and others. The best coefficient was obtained for the fruiting bodies of strain 2314 (0.87), and the worst – for 2456 (0.59), which, accordingly, is not recommended for sale by individual fruiting bodies. It was found that the fruiting bodies of high-yielding strains 2316 and 431 had a number of organoleptic defects. | Мета.

Найбільшу масу плодового тіла визначено для штаму 2301 (15,2 г), найменшу – для 2456 (3,3 г).Висновки. Визначено показники біологічної ефективності штамів. Найвищі середні значення за першою хвилею плодоношення мали штами 2316 (78,9%) із групи «зимових» (А) і 431 (78,4%) із групи «літніх» (В). За результатами статистичного аналізу встановлено суттєві відмінності між досліджуваними штамами за основними морфологічними показниками зростків. Виявлено, що маса зростків «зимових» культиварів значно менше залежить від штамової приналежності (220,8–273,4 г), ніж «літніх» (83,4–430,7 г). Запропоновано показник коефіцієнт асиметрії зростка, який може бути корисним для розрахунку необхідних розмірів тари. Виявлено, що морфологічні ознаки плодових тіл мали суттєві відмінності за всіма дослідженими параметрами. Зокрема, штами групи А відрізнялися більшими розмірами й масою. Запропоновано показник – коефіцієнт утрати маси врожаю, який показує співвідношення між шапинкою й ніжкою плодового тіла та дає змогу спрогнозувати кількість грибної сировини, яку буде реалізовано у вигляді шапинок, та кількість сировини, яку можна переробити у грибний фарш, порошок та ін. Найкращий коефіцієнт отримано для плодових тіл штаму 2314 (0,87), а найгірший – 2456 (0,59), який, відповідно, не рекомендуємо до реалізації окремими плодовими тілами. Установлено, що плодові тіла високопродуктивних штамів 2316 і 431 мали низку органолептичних недоліків.

Purpose. Morphological and organoleptic evaluation of oyster mushroom strains for selection of highly productive cultivars assortment with valuable consumer properties for winter and summer cultivation and suitability for sale in fresh or processed form were investigated. Methods. The scheme of the experiment included six strains of oyster mushrooms belonging to two species: Pleurotus ostreatus (5 strains: 2301, Z, 2316, 2456, 431) and P. pulmonarius (2314). Laboratory, laboratory-industrial and statistical methods are used. Results. The dynamics of agrochemical parameters of substrates obtained by the method of aerobic fermentation in the high layer proved their optimality according to the main criteria and compliance to regulatory documentation. The biological efficiency of the strains was in the range of 40–78.9%. The highest weight of clusters was found in the “summer” strain 431 (430.7 g). The highest weight of the fruiting body was determined for the strain 2301 (15.2 g), the lowest – for the 2456 (3.3 g). Conclusions. The values of biological efficiency of strains was determined. The highest average values for the first flush of fruiting had strains 2316 (78.9%) from the “winter” group (A) and 431 (78.4%) from the “summer” group  (B). According to the results of statistical analysis, significant differences were revealed between the studied strains in the main morphological indicators of clusters. It was found that the mass of clusters of «winter» cultivars is much less dependent on the strain type (220.8–273.4 g) than that of «summer» cultivars (83.4–430.7 g). The index of the asymmetry coefficient of the cluster, which can be useful for calculating the required container sizes was proposed. It was determined that the morphological features of fruiting bodies had significant differences in all studied parameters.  In particular, the A group strains differed in size and weight. It was proposed the index of weight loss of the crop coefficient, which shows the ratio between the cap and stipe of the fruiting body and make it possible to predict the amount of mushroom raw material that will be sold in the form of caps, and the amount of raw material that can be processed into minced mushroom, powder and others. The best coefficient was obtained for the fruiting bodies of strain 2314 (0.87), and the worst – for 2456 (0.59), which, accordingly, is not recommended for sale by individual fruiting bodies. It was found that the fruiting bodies of high-yielding strains 2316 and 431 had a number of organoleptic defects.
