Genetic variability and character association in fenugreek (Trigonella foenum-graecum L.)

Sixty four genotypes of fenugreek (Trigonella foenum-graecum) were evaluated for geneticvariability, correlation and path coefficient analysis at Jagudan (Gujarat). Phenotypic andgenotypic coefficients of variability were high for grain yield plant-1, number of pods plant-1and number of primary branches plant-1. Moderate heritability estimates along with highgenetic advance as percentage of mean were recorded for number of pods plant-1. Highheritability estimates along with moderate to low genetic advance as percentage of meanwere recorded for days to maturity and plant height. Grain yield was positively correlatedwith number of pods plant-1, number of seeds pod-1 and 1000 seed weight. Results of pathanalysis revealed that number of pods plant-1, days to 50% flowering and test weight hadhighest positive direct effects on grain yield. It was concluded that improvement of seed yieldin fenugreek is possible through selection for number of pods and seed weight throughnumber of grains and length of pods. &nbsp

Band structures and intruder π\pii13/2i_{13/2} state in 197^{197}Tl

The excited states in the odd-$A$ $^{197}$Tl nucleus have been studied by populating them using the $^{197}$Au($\alpha$, 4$n$)$^{197}$Tl reaction at the beam energy of 48 MeV. The $\gamma-\gamma$ coincidence data were taken using a combination of clover, LEPS and single crystal HPGe detectors. Precise spin and parity assignments of the excited states have been done through the polarization and the DCO measurements. A new band structure has been identified and the evidence for a possible intruder $\pi i_{13/2}$ state has been found for the first time. Possible configurations of the observed bands have been discussed. The total Routhian surface calculations have been performed to study the shape of $^{197}$Tl for different configurations.Comment: Accepted for publication in PR

Termoreverzibilni mukoadhezivni in situ hidrogel za oftalmičku primjenu: dizajniranje i optimizacija koristeći kombinaciju polimera

The purpose of the study was to develop an optimized thermoreversible in situ gelling ophthalmic drug delivery system based on Pluronic F 127, containing moxifloxacin hydrochloride as a model drug. A 32 full factorial design was employed with two polymers Pluronic F 68 and Gelrite as independent variables used in combination with Pluronic F 127. Gelation temperature, gel strength, bioadhesion force, viscosity and in vitro drug release after 1 and 10 h were selected as dependent variables. Pluronic F 68 loading with Pluronic F 127 was found to have a significant effect on gelation temperature of the formulation and to be of importance for gel formation at temperatures 3336 ºC. Gelrite loading showed a positive effect on bioadhesion force and gel strength and was also found helpful in controling the release rate of the drug. The quadratic mathematical model developed is applicable to predicting formulations with desired gelation temperature, gel strength, bioadhesion force and drug release properties.Cilj rada bio je razvoj i optimizacija termoreverzibilnog sustava za isporuku lijekova koji gelira in situ. Sustav je napravljen na bazi Pluronic F 127, a sadrži moksifloksacin hidroklorid kao modelni lijek. U radu je primjenjeno 32 potpuno faktorijsko dizajniranje s dva polimera, Pluronic F 68 i Gelrite kao nezavisnim varijablama koji su kombinirani s Pluronic F 127. Kao zavisne varijable odabrane su temperatura geliranja, čvrstoća gela, jačina bioadhezije, viskoznost i in vitro oslobađanje lijeka nakon 1 i 10 h. Pronađeno je da Pluronic F 68 u kombinaciji s Pluronic F 127 ima značajan učinak na temperaturu geliranja u rasponu od 33 do 36 C. S druge strane, Gelrite ima povoljan učinak na jačinu bioadhezije, čvrstoću gela i oslobađanje lijeka. Razvijen je kvadratni matematički model pomoću kojeg se može predvidjeti temperatura geliranja, čvrstoća gela, jačina bioadhezije i oslobađanje ljekovite tvari

Genetic analysis for earliness under varying environments in chilli (Capsicum annum L.)

Six generations P1 P2 F1 F2 BC1 and BC2 of six families were developed in chilli (Capsicum annum L.) from 11 inbreds and were used to apply A, B, C and D scaling tests in the attributes of earliness viz., days to 50.0% flowering (DTF) and days to fruit ripening (DTFR) in different environments at Jagudan (Gujarat). The experiment was conducted in Kharif 2007 under high fertility condition (E1), Kharif 2007 under low fertility condition (E2) and Summer 2007 under high fertility condition (E3). For DTFR in Kharif, low fertility and summer grown conditions enhanced the expression of dominant/partially dominant genes. Whereas, DTF in low fertility as well as late sowing conditions depressed the expression of dominant/partially dominant genes. Detection of epistasis in a cross in one environment and not in the other emphasized the influence of environment on interaction parameters. High role of epistasis for ripening and flowering in all the three environments was observed. In general, for inheritance of days to flowering preponderance of dominance gene effects or due weightage of additive and dominance epistasis and dominance × dominance gene effects were noticed. For improvement of this trait, heterosis breeding was fruitful, where importance of non-additive gene effects with greater influence of dominance gene effects was estimated. The parents GVC–111, Junagadh Gholar, JCh–730 and JCh–725 contributed desirable genes for imparting earliness. &nbsp

Approximate Analytical Solution of Advection-Dispersion Equation By Means of OHAM.

This work deals with the analytical solution of advection dispersion equation arising in solute transport along unsteady groundwater flow in finite aquifer. A time dependent input source concentration is considered at the origin of the aquifer and it is assumed that the concentration gradient is zero at the other end of the aquifer. The optimal homotopy analysis method (OHAM) is used to obtain numerical and graphical representation

Heterosis and inbreeding depression in chilli (Capsicum annuum L.)

Investigations were carried out at Jagudan (Gujarat) to study the extent of heterosis and inbreeding depression through six generation mean analysis for yield and yield attributing characters in chilli (Capsicum annuum). The magnitude of heterosis and heterobeltiosis was significant in desired direction with moderate to high for green fruit yield, secondary branches, fruit length; high for number of fruits plant-1, ripe/dry fruit weight and seed to pericarp ratio and low for flowering and ripening of fruit. The cross combinations JCh-676 x JCh-659 showed the highest estimate of relative heterosis and heterobeltiosis for dry fruit yield. All the crosses also revealed inbreeding depression for most of the characters. These traits can be improved effectively through pedigree method of selection. In general, the crosses JCh-730 x JCh-725 and JCh-676 x JCh-659 were identified as promising hybrids since they depicted significant heterosis for green and dry fruit yield and its important yield contributing characters. &nbsp
