In 2014, I had planted 210 lines, 3 checks (1 repeated check & 2 random checks) in augmented design 1 replication, 1 location ( 2 loc were planted but lost 1 loc for late freeze damage). These 210 lines comes from 12 populations (Family structure is complex I have 7 wild relatives back crossed to 2 elite parents). In 2015 out of 210 lines, 93 were advanced to next generation based on tillering ability (alpha lattice, 2 replications, 4 locations). I have done BLUPs and BLUEs for 2015 using META & I got heritability for 2015. I have done moving mean analysis using Agro Base Gen II for 2014. End of the day I have to calculate genetic gain we have achieved for grain yield by indirect selection for tillering ability. Please guide me step by step
Yes you definitely can. Data from an augmented design can be analyzed using ReML to estimate the (additive) genetic variance and phenotypic variance - that will give you an estimate of heritability, with which you can estimate the genetic gain. Narrow sense heritability is preferable to get a realistic estimate of genetic gain. A step by step explanation, while possible, will however take time. Best would be talk to someone locally who can help you with this.
Thank you sir,
Spoke to many scientists on campus they think it's not possible. It will be great if you can help me. If you have time I can call you or we can communicate by email. Please let me know your I'd. My Id: [email protected]
Thank you in advance

Have you talked to a local statistician Bharath? Resolving this issue remotely - via phone or email, if not impossible, will be difficult. Check with Rupa who might help. Anyway my email ID is: [email protected]
Thank you sir I will talk to Rupa & other statisticians. If I can't answer I will get back to you.
Regards,
Bharath
