A field experiment conducted for screened 288 elite gen pool of linseed against bud fly infestation at Kanpur, India during rabi 2011-12 and 2012-13. The flowering duration showed significant positive relationship (r=0.9278 and 0.9368) with bud infestation. The maximum flowering duration 32.80 and 31.44 days was recorded on variety A-44 with highest bud infestation of 62.29 and 69.99 percent during respective years against variety C-C-1-2 which had a shortest flowering duration of 8.80 and 12.94 days with the minimum 16.38 and 14.30 percent bud fly infestation. Categorization on the basis of flowering duration and damage caused by the bud fly, were found, flowering duration range (11.80- 18.30) and (12.94-21.44), number of entries 11 and 8 were resistant, (0-10 %), flowering duration range (11.80-20.80) and (11.44-25.94), number of entries, 164 and 146 moderately resistant, (10 to 25%), flowering duration range (12.80-30.80) and (11.44- 28.94), number of entries 98 and 116 moderately susceptible, (25 to 50%), flowering duration range (24.80-33.30) and (21.94-32.44), number of entries 15 and 18 susceptible, (50 to 75%), none of the varieties found highly susceptible (more than 75%) to be bud fly attack during 2011-12 and 2012-13, respectively. The variety having longer flowering duration was severely infested by bud fly as compared to those with shorter flowering duration.

The resistant germplasm line maximum sepal thickness (0.49 mm) had relative minimum bud infestation (6.88%) while minimum sepal thickness (0.24 mm) with maximum bud infestation(65.11%), plant height, flower colour did not show significance in bud fly resistance, whereas, flowering duration bud as well as sepal thickness showed significant impact.

A field experiment conducted for screened 288 elite gen pool of linseed against bud fly infestation at Kanpur, India during rabi 2012-13 to study the bud structure of resistance of linseed against bud fly. The results indicated that the bud length and width showed significant positive correlation coefficient relationship (r=0.1559 and 0.0761) bud infestation. The resistant germplasm line minimum (GS-234) minimum bud length and width (7.93 ×3.26 mm) had relative minimum bud infestation (6.88%) and was statically at par other resistant germplasm lines viz. A-95B, CI-1385, EC-1392, EC-1424, GS-234, IC-15888 and JRF-5. While susceptible germplasm line (Arny) exhibited maximum bud length and width (8.25 ×3. 23 mm) maximum bud infestation(65.11%) which was statically at par with other susceptible lines viz. Ajgan-3-1, Ajgan-20M, Alipur (Hamirpur), Anand, GS-148, GS-440, Gunawal Local, NP(RR)193, RAULD-7810, RLC-28(PM), MS-14, SJKO-2, SJKO-45.

Цель исследования заключалась в разработке эффективной селективной системы invitro для создания устойчивых к антракнозу генотипов льна. В качестве объекта исследований использованы сорта и линии льна Linum usitatissimum L., различающиеся по устойчивости к антракнозу. Штаммы гриба, включённые в исследования, различались по вирулентности. В исследованиях использовали методики Доспехова, Курчаковой, Методические рекомендации по созданию, поддержанию, хранению и практическому использованию Коллекции микроорганизмов возбудителей болезней льна. В результате разработана селективная система invitro гриб Colletotrichum lini Mannset Bolley лён, позволяющая отбирать клетки льнадолгунца invitro, устойчивые к культуральному фильтрату, из которых с большей эффективностью можно получать растениярегенеранты, устойчивые к патогену. В культуральных фильтратах исследуемых штаммов возбудителя установлено наличие аминокислот: аланин, глицин, аспарагин, цистеин, аспарагиновая и глютаминовая кислоты, аргинин, треонин. Выявлена зависимость отзывчивости клеток льна на присутствие в среде продуктов жизнедеятельности гриба возбудителя антракноза от величины экспланта. Клетки пыльников в селективных условиях были более уязвимы, чем клетки незрелых зародышей. Выявлено влияние генотипа льна на потенции клеток к морфогенезу в селективных условиях. Клетки генотипов Л 95787, Алексим, Пенджаб, Зарянка обладали высокой морфогенетической активностью. Морфогенетический потенциал генотипов Л 150684, Росинка был исчерпан уже ко 23 пассажу. При разработке схемы селекции льна invitro на устойчивость к антракнозу получено 86 побегов, проверка которых на искусственном инфекционнопровокационном фоне показала, что генотипы различались по устойчивости. Наряду с устойчивыми и среднеустойчивыми к антракнозу линиями (на уровне 5075) были и формы, восприимчивые к болезни. У устойчивых и среднеустойчивых генотипов параметры устойчивости были на 1237 выше, чем у исходных форм.The purpose of the research was to develop an effective selective system invitro for the creation of flax genotypes resistant to anthracnose. Flax varieties and lines of Linum usitatissimum L. differing in resistance to anthracnose were used as the object of research. The fungal strains included in the researches differed in virulence. Dospekhov and Kurchakovas methods, Methodical recommendations on the creation, maintenance, storage and practical use of the Collection of microorganisms of flax pathogens were used in the researches. As a result, a selective invitro system called Fungal Colletotrichum lini Mannset Bolleyflax has been developed which allows the selection of cells of longstalked flax invitro resistant to culture filtrate from which pathogenresistant regenerants can be obtained with greater efficiency. In the culture filtrates of the studied pathogen strains the presence of amino acids is established: alanine, glycine, asparagine, cysteine, aspartic and glutamic acid, arginine, threonine. The dependence of the responsiveness of flax cells to the presence in the environment of waste products of the fungus, the causative agent of anthracnose, on the size of the explant was revealed. Anther cells under selective conditions were more vulnerable than cells of immature germs. The influence of flax genotype on cell potency to morphogenesis in selective conditions has been revealed. Cells of genotypes L 95787, Alexim, Penjab, Zaryanka possessed high morphogenetic activity. The morphogenetic potential of genotypes L 150684, Rosinka was exhausted already by passage 23. When developing a plan for the selection of flax invitro for resistance to anthracnose 86 shoots were obtained, checking them on an artificial infectiousprovocative background showed that the genotypes differed in resistance. Along with resistant and moderately resistant to anthracnose lines (at a level of 5075), there were also forms susceptible to the disease. In resistant and moderately resistant genotypes, resistance parameters were 1237 higher than in the original forms.
