Given the potential use of flax in metal-contaminated soil remediation programs, the uptake and accumulation of cadmium was studied in five varieties of flax (Linum usitatissimum L.) including var. Belinka, Escalina, Jitka, Marina and Krasnoder. Early stage plants in hydroponics were exposed to Cd to assess their tolerance by means of growth parameters and content of photosynthetic pigments. All varieties exerted tolerance indexes in the range of 63 – 89 %, while oxidative stress was not detected in either variety. Chitinase enzymes were analyzed in leaf protein extracts since activities of these enzymes have previously been correlated with plant tolerance to Cd. However, total enzyme activities remained unchanged in presence of Cd in all flax varieties. A more detailed analysis of these enzymes identified up to 3 chitinase isoforms upon separation of leaf protein extracts in polyacrylamide gels, and their quantification confirmed responsiveness to Cd for each of them. The obtained data were interpreted in light of metal uptake rate, which we measured using gammaspectrometry in growth media spiked with 109Cd and in the plant tissue. The variety Jitka showed the most sensitive to Cd and accumulating fast and the highest amounts of metal. In contrast, the variety Belinka appeared most tolerant, accumulating the least Cd in a slow rate. Activation of chitinase isoforms correlated with more sensitive varieties and suggests activation of general defense mechanisms. The obtained data suggest the variety Jitka as most promising for phytoremediation programs and the var. Belinka as the most suitable when avoidance of potential health risk is of interest.

The aim of this trial was to compare the influence of supplementing diets with extruded linseed and oregano on growth parameters and meat qualitative traits in Grigia di Potenza breed suckling kids. Twenty-four male kids, exclusively fed milk from their dams, were assigned to the following diets: C) group control fed without any supplement; L) group fed control feed containing 3% extruded linseed (Linum usitatissimum L.); and LO) group fed control diet with 0.6% dried oregano (Origanum vulgare) and 3% extruded linseed. Growth performance as well as slaughtering traits and meat cuts of kids were not significantly influenced (P > 0.05) by dietary treatments. Conversely, kids in linseed group reported the lower (P < 0.05) percentage of dissectible fat in leg and loin. The meat from Longissimus lumborum and Semimembranosus muscles of kids in linseed diet had the lowest (P < 0.05) cooking loss percentage, whereas the proximate chemical composition of both meat muscles did not vary among treatments (P > 0.05). The experimental diets partially modulated the kid meat fatty acid composition in both muscles, where feeding linseed and oregano improved (P < 0.05) the content of DPA and reduced MUFA. Based on the current findings, it can be concluded that linseed and oregano supplementation can be used in goat diet as no significant detrimental effects on productive performance and meat quality of suckling kids were observed. © 2021 Friends Science Publishers

A field experiment was conducted to study the effect of agro-input management practices on yield of linseed (Linum usitatissimum L.) at the Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.) during Rabi 2015-16. Different agro input management practices had significant (P=0.05) effect on growth, yield attributes and yield of linseed. However, seed rates did not give significant influence on seed yield. Whereas, application of RDF + FYM placement in rows @ 5 t ha-1 (N3) recorded significantly (P=0.05) higher growth parameters viz. plant height (88.44 cm), primary branches plant-1 (3.83), secondary branches plant-1 (23.39), dry matter accumulation (6.76 g plant-1) and yield attributes viz. capsules plant-1 (30.86), seeds capsule-1(7.63), seeds plant-1 (235.32), seed yield (2100 kg ha-1) and stover yield (4885 kg ha-1). In case of foliar spray, application of 2 % urea at 15, 40, 65 and 90 DAS (F3) gave significantly higher growth parameters viz. plant height (88.37 cm), primary branches plant-1(3.82), secondary branches plant-1 (23.68), dry matter accumulation (6.59 g plant-1) and yield attributes viz. capsules plant-1(31.74), seeds capsule-1(7.63), seeds plant-1 (241.38), seed yield (2089 kg ha-1) and stover yield (4772 kg ha-1). Interaction among seed rate 30 kg ha-1 (S2) X RDF 60:30:30 N: P: K kg ha-1 (N1) with foliar application of 2 % urea at 15, 40, 65 and 90 DAS (F3) (S2 XN1X F3) recorded the highest benefit-cost ratio (4.39). Line placement of FYM was better than broadcasting in terms of seed yield; and foliar application of urea was economical than Nitrobenzene.

Combining ability and heterosis were calculated for fourteen lines of linseed in a line × tester mating design using twelve lines and two diverse testers in two different environments. The hybrids and parental lines were raised in a completely randomized block design with three replications to investigate seed and fibre yield and their component traits. Genetic variation was significant for most of the traits over environments. Combining ability studies revealed that the lines KL-221 and LCK-9826 were good general combiners for seed yield and most of its components, whereas LMH-62 and LC-2323 were good general combiners for yield components only. Moreover, KL-221 was also a good general combiner for fibre yield. Similarly, B-509 and Ariane were good general combiners for fibre yield and most of its components. Among the specific cross combinations, B-509 × Flak-1 was outstanding for seed yield per plant and B-509 × KL-187 and LC-2323 × LCK-9826 for fibre yield per plant, with high SCA effects. In general, the hybrids excelled their respective parents and the standard checks for most of the characters studied. Based on the comparison of mean performance, SCA effects and the extent of heterosis, the hybrids LC-2323 × LCK-9826 and B-509 × KL-221 appeared to be the most promising for both seed and fibre yield. Other promising combinations were LC-2323 × KL-210 and B-509 × Ariane for seed and fibre yield, respectively. The superiority of LC-2323, LCK-9826, KL-221, B-509 and Ariane as good general combiners was further confirmed by the involvement of these parents in the desirable cross combinations.
