Field Performance and Genetic Analysis in Some Advanced Lines of Mustard (<i>Brassica rapa</i> L.)

Abstract

Twenty four genotypes including four check varieties of mustard (Brassica rapa L.) were collected for estimating the genetic variability, heritability, genetic advance of different characters related to the yield and yield components. The experiment was conducted at the Sher-e-Bangla Agricultural University research farm, Dhaka during 2013-2014. Days to 50% flowering and days to 80% maturity showed moderate difference between the phenotypic and genotypic variance whereas, minimum differences were found in number of primary branches plant , no. of seeds siliqua -1 showed high heritability coupled with low genetic advance in percentage of mean. The study showed that variations in the extent of genetic variability, heritability and genetic advance in traits under study which can facilitate selection for further improvement of important traits of Brassica rapa L.

Genetic Diversity Estimation in Toria [Brassica rapa (L)] Genotypes Collected from Bastar Plateau

“…Thus indicating that these were the traits which must be considered while selecting plant for the crop improvement. The findings of present study were in agreement with the findings of Rai et al, (2005), Bind et al, (2013), Shekhawat et al, (2014) and Hussain et al, (2016).…”

“…Moderate PCV and GCV were recorded for days to 50% flowering (10.35%, 10.05%), seed per siliqua (14.71%, 14.54%) and plant height (17.69%, 17.59%) whereas rest of the traits indicated low PCV and GCV. This estimates of the present study were similar with the findings of Rai et al, (2005), Akbar et al, (2008), Aytac and Kinaci (2009), Bind et al, (2014), Singh et al, (2013), Tripathi et al, (2013), Lodhi et al, (2014, Shekhawat et al, (2014), Samahegn andTesfaye (2016) and Hussain et al, (2016). ).…”

To Study the Genetic Variability, Heritability and Genetic Advance for Different Quantitative Characters in Indian Mustard (Brassica juncea L. Czern & Coss)

“…As additive gene action is pronounced in the expression of these characters. Similar result were reported by Rai et al, (2005), Tripathi et al, (2013), Singh et al, (2013), Shekhawat et al, (2014, Lodhi et al, (2014), Hussain et al, (2016) and Samahegn and Tesfaye (2016), Kumar et al, (2018). Kumar et al, (2018) revealed the existence of considerable genetic variation among the breeding lines for the characters under study, which can be used for further selection and hybridization.…”

Genetic parameters and diversity studies of yield and yield contributing characters in Brassica genotypes

“…Similar findings were earlier reported by Sikarwar et al (2017). Hussain et al (2016) and Mekonnen et al (2014) also observed high heritability for days to 50% flowering, days to 80% maturity, number of primary branches/ plant, number of seeds/pod, pod length, number pod/plant, 1000-seed weight and yield/plant.…”
