M4 generation

Knowledge about heritability and genetic advance on yield and yield contributing characters are necessary for the crop improvement through selection. The present investigation was therefore planned to estimate and evaluate different genetic parameters in 283 mutants for 11 characters.

An investigation was carried out to study the effects of various doses (0.2 to 0.6%) of EMS on physico-quality traits of groundnut (Arachis hypogea L) in M4 families of the groundnut variety TPG 41. Among the different concentrations of EMS treated TPG 41 population, 0.2 % EMS was found to be effective in inducing variability for pod yield per plant, hundred kernel weight, shelling out turn and kernel length in M4 families.

Micropropagation is a highly sought after technique in the commercial production of orchid plants. This has the advantage of providing large number of plants in a short period of time. But a major constrain in the in vitro propagation technique is the somaclonal variation. It is important to produce true to type planting materials especially in case of the hybrids as they are more prone to variations. The true to type nature of the micropropagated plantlets can be confirmed by genetic fidelity analysis.

Advanced mutant lines have been selected from M4 generation and its qualitative and quantitative characters were evaluated in spring-summer season at Bidhan Chandra Krishi Viswavidyalaya, West Bengal, during 2016. Different qualitative characters of mutant lines have been recorded and observed that the some characters changed from that of the parental control. Analysis of variance due to treatments was significant for all the characters proved higher variability among the mutant lines.
