Important Trait

Background: Seed yield is a very important trait for selection but shows low heritability and hence is difficult to improve. Since the productivity of linseed (Linum usitatissimum L.) in India as well as Himachal Pradesh is low in comparison to other major linseed growing countries and states, improvement in cultivars for grain yield is a must. Therefore, the present study was aimed for studying the character associations in linseed genotypes for seed yield over locations. Method: The experiment was conducted during rabi 2019-2020. The experimental material for the present investigation comprised of 52 linseed genotypes grown over three locations in Himachal Pradesh i.e. Linseed Experimental Farm, CSK HPKV, Palampur (1290 m amsl), Shivalik Agricultural Research and Extension Centre, Kangra (700 m amsl) and Hill Agricultural Research and Extension Centre, Dhaulakuan (468 m amsl). Randomized block design with three replications was used. Phenotypic and genotypic correlation coefficients were worked out as per the procedure outlined by Burton and De Vane (1953) and Johnson et al. (1955). Direct and indirect effects of component traits on grain yield were worked out using correlation coefficient of various traits as suggested by Wright (1921) and elaborated by Dewey and Lu (1959). Result: Correlation studies indicated highly significant positive correlation for seed yield with 1000 seed weight (0.965**) followed by harvest index (0.801**), secondary branches (0.585**) and a significant correlation with biological yield (0.269**). Seed yield exhibited a non-significant positive correlation with seeds per capsule. However, a negative significant correlation was observed for seed yield with days to 50 per cent flowering and number of primary branches. The path coefficient analysis indicated that 1000 seed weight exhibited maximum positive direct effect with seed yield (0.741) while others had a low direct effect. The significant positive correlation of number of secondary branches and harvest index with seed yield was mainly due to indirect effect via 1000 seed weight indicating that 1000 seed weight is the most important trait for the improvement of grain yield in linseed as per the present study.

Abstract Our purpose was to compare with respect to fecundity and longevity two groups of F1 diploid virgins of Habrobracon the fathers of which had been X-rayed with 3000r. Sorting of wasps into two groups was based on low or high hatchability of their F2 haploid eggs. Wasps with low hatchability (below 60%) are heterozygous for induced embryonic lethals such as recessives and translocations; wasps with high hatchability (100–60%) are free of lethals or possibly heterozygous for mild detrimentals. The F1s showing high hatchability laid significantly more eggs on the average; the average difference in lifespan was almost statistically significant (7% level). A more sensitive analysis by regression indicated a highly significant linear regression of survival of all F1s on hatchability of their eggs: F1s whose eggs showed 100% hatchability lived 1.84 days longer on the average than those whose eggs showed no hatchability. Furthermore, the former laid 4.99 more eggs on the average than the latter. The data also showed a very highly significant positive correlation coefficient between eggs laid and survival of mothers (0.122***) and a very highly significant positive partial correlation coefficient (0.105***) with hatchability held constant. The latter indicates that the F1s which laid more eggs also live longer, regardless of the hatchability of their eggs and hence of the heterozygosity of the mothers for lethals and other detrimentals.

&lt;p&gt;Diz alteration area is situated in the southern part of Ardabil province in the northwest of Iran. This alteration area is a limited part of Tarom-Hashtjin volcanic zone. The hydrothermal alteration process has been mostly taken place in pyroclastic and volcanic units such as tuff, ignimbrite, and trachyandesites. The alterations of this area are related to Eocene volcanism which has considerably developed in the northwest of Iran. The argillic alterations in Diz area are mainly seen in ignimbrite unit and the precursor rock has been intensely altered such that many parts of the parent rock has been fully leached and all of the mobile elements have been removed from the parent rock while the resistant elements such as Al, Si, and some other immobile elements have remained in the context. Considering to the special behavior of REEs in the weathering and alteration profiles, depending on the REE bearing mineral&amp;#8217;s resistivity against weathering and alteration processes, REEs can be removed or fixed in the environment. In the studied samples different concentrations of REEs are observable.&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160; &amp;#160;&lt;/p&gt;&lt;p&gt;The drawn REE diagrams show unique patterns for the studied samples where Ce group elements (LREEs) show a slight enrichment comparing to Y group (HREEs). The comparison of LREEs with HREEs represents that LREEs have been enriched 4 times more than HREEs.&lt;/p&gt;&lt;p&gt;The positive correlation coefficient between &amp;#931;REE and TiO&lt;sub&gt;2 &lt;/sub&gt;(R&lt;sup&gt;2&lt;/sup&gt;=0.70) represents the role of Ti bearing minerals such as ilmenite, pyroxene, rutile, and anatase in the fixation of REEs. On the other side the presence of considerable amounts of P&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5 &lt;/sub&gt;in the studied samples and also the positive correlation coefficients between P&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5 &lt;/sub&gt;and LREEs (R&lt;sup&gt;2&lt;/sup&gt;=0.90), and P&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt; and &amp;#931;REE (R&lt;sup&gt;2&lt;/sup&gt;=0.74) suggest that some minor minerals such as monazite (Ce,La,Nd,Th)(PO&lt;sub&gt;4&lt;/sub&gt;,SiO&lt;sub&gt;4&lt;/sub&gt;) must be considered. The positive correlation coefficient between Al&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3 &lt;/sub&gt;and &amp;#931;REE shows the influence of clay minerals in the adsorption of REEs.&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160; &amp;#160;&lt;/p&gt;&lt;p&gt;The evaluation of REE patterns normalized to chondrite show a remarkable peak for Gd. Geochemically, Gd shows similarities with Ca&lt;sup&gt;2+&lt;/sup&gt;. The Gd complexes may decompose in the presence of some elements such as Cu, Y, and REEs and Gd&lt;sup&gt;3+ &amp;#173;&amp;#173;&lt;/sup&gt;can be released. Hence, CaO is a main component in the parent rock of the studied altered samples, the positive Gd anomaly is most likely related to the primary composition of the parent rock. Furthermore, the decomposition of Gd complexes in the presence of competitor elements and also the high Gd content of altering fluids can be thought as the main reasons of Gd positive anomaly in the studied samples.&lt;/p&gt;

Mangrove forest and the community lived around it are two components that influence each other. The interaction between the two of them is unavoidable because they live in the same environment. Activities, perceptions or actions of the community can affect the sustainability of the existence and the preservation of mangrove forest. This study aims to describe the community perceptions towards mangrove forest and to analyze the correlation that affects community perceptions in Setapuk Besar village towards the level of knowledge, dependence, and cosmopolitanism. The technique of sampling employed in this study is purposive sampling. Based on Slovin formula, a total sample of 74 respondents was obtained. The frequency of community perceptions in Setapuk Besar village on the existence of mangrove forest are: 67 respondents (90.5%) had positive perceptions, 6 respondents (8.1%) had neutral perceptions, and 1 respondent (1.4%) had negative perception. From the results of Kendall tau-b test, the value of Sig 0.000 < 0.01 and Sig 0.028 < 0.05, which indicates that there is a significant correlation between community perceptions with the level of dependence positive correlation (0.419), the correlation strength is moderate. Cosmopolitan level positive correlation (0.190), the correlation strength is low.  While the value of Sig 0.170 > 0.05, which indicates that there is no significant correlation between community perceptions and the level of knowledge positive correlation coefficient (0.119), the correlation strength is low.Keywords: Community perceptions, mangrove forest, Respondents, Setapuk Besar

Aerosol light scattering measurements were carried out using a TSI 3563 Nephelometer at the Mace Head Atmospheric Research Station, on the west coast of Ireland from year 2001–2010. A strong seasonal trend in the aerosol light scattering coefficient at 550 nm (), for clean marine air masses, is observed with a high value, [average (geometric mean)] of 35.3 Mm−1(29.5 Mm−1), in January and a low value of 13.7 Mm−1(10.2 Mm−1), in July. This near threefold increase in the value during the winter season is because of the large contribution of wind-speed generated sea-salt particles in the marine boundary layer. A high positive correlation coefficient of 0.82 was found between the percentage occurrence of relatively large Ångström exponent (Å) values (>1.2) and the percentage occurrence of lower values (5–15 Mm−1) in the summer season. and wind-speed have a high positive correlation coefficient of 0.88 whereas Å and wind-speed have a negative correlation coefficient of −0.89. Å values during the summer months indicate the dominance of sub-m particles thus indicating the contribution of non-sea-salt sulphate and organics towards the as these species show an enhanced concentration during the summer months.
