Fieldbook: How to enter data directly into excel by using android smartphone with help of barcodes.
Data entry is one of the fundamental part of the research, which is required for data analysis. Traditionally everyone record the data in the observation book or in observation sheets and later they enter the data into excel sheet manually, which at least requires two persons. But in modern day research we can use many number of tools, one important among them is Fieldbook app from Phenoapps, which is a free software to record the observations.
Fieldbook can be used along with the barcoded labels, from which we can scan the label and directly access the entry with unique Id. This makes data entry very feasible as we do the randomisation in field.
Software required

Diversity found in Pea (Pisum sativum) | Mendelian traits | DUS guidelines
Просмотров 6832 года назад
This video depicts the diversity present in the pea (Pisum sativum) with beautiful pictures, The diversity in peas was studied by Gregor J. Mendel whom we considered as "Father of Genetics". These traits were the basis of observation which involved in deriving the two fundamental principles/laws of genetics. The traits include Flower colour. Seed colour Seed shape Seed sufrace....

Multivariate D-Square statistics in R/Tocher method of clustering for genetic diversity assessment
Просмотров 12 тыс.3 года назад
Hi there in this video, I have shared the complete procedure involved in Multivariate D-square statistics in plant breeding, using Mahalanobis squared euclidian distance for assessment of genetic diversity in plants. This is a second order statistics not the most accurate one as compared to Metroglyph analysis but can be used for more number of individuals, with replications only ~ Here I am us...

Augmented block design data analysis in R (R-studio).
Просмотров 14 тыс.3 года назад
This video includes all the details required for data analysis of augmented block design using R studio with "augmentedRCBD" package written and archived by Aravind J. This design is used when the genetic material required for replication is not sufficient. The results from this analysis include ANOVA (Treatment and Block adjusted ), genetic variability parameters (GCV, PCV), adjusted means. 00...
hello sir, my design was Augmented 2 with 7 blocks ..210 RILs of sorghum , with 6 checks replicated in each block . In case of this should igo for hierarchical clustering analysis using k means and include adjusted mean of 210 lines for analysis. . am I right s? I have to do interpretation on the bases of fodder yield. ..so is their any specification for doing trait wise clustering.. I have taken quantative traits along with shoot fly associated dead heart percent etc traits .. as my RILs are the population of shoot fly susceptible x resistance cross .... so how should I proceed for the analysis on diversity for forage sorghum based on my characters ...total 18 characters were taken..... Should I limit my traits according to my objective of interpretation ..or should I subject all the traits .... .is for non replicated data non hierarchical clustering Is different from hierarchical ?
I have an doubt. In manova I cannot get the results. It shows there are more variables ie..26<32. My data have 32 variables
I have problem with finding clusters!
Thank u sir. But can we save the same thing in notepad instead of word file
Yup.
Also I wanted to ask how to use this adjusted mean data for path analysis. Under $replication what we have to provide. Since only the checks are replicated
@@chaminchimyang4689 You only consider the mean value for path analysis.
Can you please explain about mixed models too?
This is the best video on this topic in net
Finally i have done it successfully, thank you for your patient explanation and recording
Sir given links in IRRI are not opening, plz help
I am doing this analysis in R studio for the first time, every thing went fine upto AMMI analysis, after that AMMI based plots are not comig. In the function AMMI_indexes it is not showing options to select amod1 or amod 2. please clarify how to proceed further
After calculating d sq distance according to privious video. Then according to this video number of cluster is different how we can solve this. Please respond
You won't get similar results stick to one method.
Kindly suggest when no. Of genotypes are less than no. Of traits, these codes are not giving results. It gave best results when genotypes were either more in number or equal to no. of observations.
Not soo, i think.
@@Guruprasad_A can we work for less no of genotypes and more observed traits?? If so then I have to check my data
@@asingh9317 Sure, but inorder to study we need more genotypes.
@@Guruprasad_A got it...thanks alot🍁🍁
What should i do if i am having data from augmented design??
Not possible, if the design is augmented.
I have error when starting the app, any idea?
Have you installed the R version 1.5 ?

Very good explanation, the pea.xlsx file can you post it? Did you publish your findings ?
Sir this video of yours are very much informative, clean and clear. It will be much more appreciated if you would kindly explain for Eberhart and Russell analysis also
Anyone..do you have email ID of Sir, please share
Excellent information, thanks for explaining every step very clearly
Hi sir Thanks for your videos... I request you to share the videos on AUGMENTED BLOCK DESIGN FOR MULTI LOCATION
It is not an appropriate design for multi location trail.

Sir I am using 10 blocks in which 10 F2 population ,3 check, 2 parents and 1 F1 parent in my research, is it correct?
When I run NbClust(data=rice.s, diss= NULL, distance= "euclidean", min.nc = 2, max.nc = 15, method = "complete", index= "all", alphaBeale = 0.1), then I got the following error: Error: division by zero!Error in solve.default(W) : Lapack routine dgesv: system is exactly singular: U[6,6] = 0 How can I solve this? Thank you.
Change the index.
Sir can you explain elaborately, how to do cluster means
Group them individually / seperate the groups in different Excel sheet then take average.
Hello sir. This video helps a lot for my studies. Can you help me fix this one problem wherein the app exits on its own🥲
thank you. Best turorial!
sir,how to make the circular cluster dendrogram
I have loaded corrected means from augmented RCBD.. But one numerical trait is taken as character.. after changing to numeric it is showing values as 'NA' for all genotypes... This unable to proceed with k means .. it is showing error... How to go about..? Kindly help..
Check there might be problem in the data what you have entered. There might be double pulstop or a alphabet like o instead of zero.
Sir i have doubt, how to write multivariate D2 analysis and ward D2 method hierarchical clustering in thesis, they differing in cluster partition.
You go with one which suits you. Mostly for diversity studies D2 test is better.
Hello sir it shows data is of type tibble and it also shows test treatments are replicated can you plz help me out
Tibble warning doesn't have any problem with results, but check the replications (checks) name or order correctly in the Excel sheet.
Warning message: `mean_by()` is deprecated as of metan 1.17.0 Please use `mean_by()` instead ???
You can ignore the warning.
God type explanation, thank so much sir❤
Very informative vedio Sir Sir in wrapper function for plant height trait, after appling ge_stats function I'm getting error as error in rowsums((gamma.n) ^)2) : 'x' must be an array of at least two dimensions. How to fix it sir
I think only one principal component is retained, so you are getting that error. Just drop the options of ammi from ge_stats and proceed.
Thank you very much for the big help Sir. I can use it to my research
could you please share the cotton data?
Great. Can we replace environment with year. I have experiment on estimation of yield of different genotypes. I have 3 years data.
Yup
I want to do path analysis for augmented blockdesign plz help
Use the average data and you can do in amos SPSS software...

How to perform correlation network plots in R
My parameter is anthocyanin, in 26 genotypes accross 2 environment can i put ammi for that ? i tried using ammi model but , the error of the analysis ammi is not possible. both genotypes and environmnet must have more than 2 levels...how can i proceed .. what needs to be done kindly let me know
That's because there is no much diversity in your parameter. What sort of anthocyanin data you have.
Very insightful tutorial
Sorry I get this error (bad restore file magic number (file may be corrupted) -- no data loaded In addition: Warning message: file ‘yield.xlsx’ has magic number 'PK' Use of save versions prior to 2 is deprecated ) when I load the excel file. Please guide and help me. Thanks
Load csv file not excel file.
very useful lecture sir, thanks
