Abstract Factors infl uencing the morphogenic capability of linseed fl ax cultivars 'Lirina', 'Barbara' and 'Szaphir' in tissue culture were determined. Two different types of explants (stem segments and hypocotyls) of the three genotypes were cultivated in nutrient media differing in their macro and micro salts concentration and different levels of growth regulators. Our results showed, that callus induction, root formation and shoot regeneration was possible in all types of nutrient media. However, the intensity of morphogenesis was affected not only by the used exogenous growth regulators, but also by the type of explant and genotype. Hypocotyls from all tested genotypes were more responsive in shoot induction than stem segments on all tested media. Calli, shoots and roots were derived at the same time from tested explants in all media depending on the genotype. The best morphogenetic capabilities were demonstrated for cultivar 'Szaphir'. For all cultivars the largest number of shoots was produced on MSB 5 nutrient medium supplemented with cytokinin 6-(y-y-dimethylallylamine)purine (2.0 mg 1 -1 ).

Abstract: Experiments were conducted to investigate the "paired" arbuscules characteristic of Arum-type mycorrhizal colonization in Linum usitatissimum L. The development and senescence of arbuscular structures were followed in a time course study. Roots were freeze

Abstract: Linum species is oil seed that has oil percentage with a good quality in point of view omega-3 essential fatty acids. Linum usitatissimum (crop species of Linum genus) has two sub species. The aim of this study is to introduce better sub species for agricultural purposes. Important

Agrobacterium-mediated plant transformation via floral-dip is a widely used technique in the field of plant transformation and has been reported to be successful for many plant species. However, flax (Linum usitatissimum) transformation by floral-dip has not been reported. The goal of this protocol

ABSTRACT Field studies were conducted at S. V. Agricultural College, Tirupati, India to document the diversity, abundance and foraging activity of insect visitors/pollinators on linseed. The species diversity was high with 19 insect species visiting the linseed crop during flowering phase. The insect species included nine lepidopterans, three hymenopterans, three hemipterans, two dipterans, one coleopteran and one orthopteran. Among these, Muscid fly and Halictus sp. were the most frequent and abundant visitors to the floral heads of linseed. The abundance of Muscid fly was highest (0.40 flies/ m 2 / 5 minutes) followed by Halictus sp. (0.31 bees / m 2 / 5 minutes). Among all insect visitors, Diptera order constituted the major chunk of pollinators (32.00%) followed by Hymenoptera (31.36%), Lepidoptera (21.98%), Hemiptera (10.66%), Orthoptera ( 0333%) and Coleoptera (0.67%). Of the total insect visitor population, muscid fly constituted maximum proportion (32.00 %), followed by Halictus sp. (24.70%) . The peak foraging activity of frequent insect visitors was observed between 08.00 and 09.00 h.

ABSTRACT: Thirty diverse genotypes used to study their stable performance over three environmental conditions viz., rain fed, irrigated and late sown conditions, respectively for seed yield and its attributing characters. Significant genotype x environment interaction was observed for all the characters under study. Linear component of G x E interaction was also significant for almost all the characters except days to 50% flowering, number of primary branches per plant and harvest index. None of the genotypes showed stable performance for all the characters. The genotypes R-2510, R-2511, R-2516 were showed stable performance for three characters, R-2526, R-2527, J-23 stable for two characters and rest of the genotypes showed stable performance for one character over a range of environments under study.

Abstract- In this study, flaxseed was subjected to identification of bioactive compounds by using Gas Chromatography-Mass Spectrum technique. Flaxseed was extracted with 99%ethanol. Extracted sample was injected, according to, the bioactive compounds are screened. The results revealed the presence of seventeen compounds of which squalene (45.27 %) and 9, 12, 15-octadecatrienoic acid (z,z,z) (24.67) were the phytocomponents with high peak areas.
