Studies on seed quality parameters in Indian mustard [Brassica juncea (L.) Czern and Coss]

Abstract

An evaluation of thirty two accessions of Indian mustard [Brassica juncea (L.) Czern and Coss] was carried out during 2014-2015 in Completely Randomized Design (CRD) with three replications in Laboratory revealed highly significant differences among the accessions for all seed vigour traits. Observations were recorded on ten seed vigour traits viz.,1000-seed weight (g), field emergence (%), speed of germination (at field), germination, speed of germination, root length (cm), shoot length (cm), seedling length (cm), seedling dry weight (mg) and vigour index. Highly significant differences were observed among the genotypes for all the seed vigour traits. The phenotypic coefficient of variability (PCV) ware close to genotypic coefficient of variability (GCV) for more of the traits which indicate that environmental effect has no considerable effect on the total phenotypic variation. Heritability and genetic advance indicated that the nature action and reliability or those characters for selection and emerged as ideal traits for improvement through selection.

Cause and Effect Relationship in Yield and Its Attributing Traits in Early Segregating Generations of Mustard Crosses under Terai Agro-Climatic Zone of West Bengal, India

“…A close proximity in PCV and GCV was observed in plant height, height up to first fruiting branch, days to 50% flowering, days to physiological maturity and siliquae per plant in both the generations except siliquae per plant in F 3 generation indicating little influence of the environment in the expression of these yield attributing characters studied. Similar results were obtained by Singh et al, (2015) and Srivastava et al, (2016).…”

Evaluation of Heritability and Genetic Advance for Morphological Traits of Indian Mustard Germplasms

“…This showed that there was least influence of environment in the expression of traits. High GCV and PCV were earlier reported Srivastava et al [14] and Rauf and Rahim [13].…”

Effect of Integrated Nutrient Management on Mustard Crop (Brassica Juncea L.)

“…A number of research workers have observed increases in these attributes in mustard crop viz. Sahoo et al (2018) and Singh et al (2014).…”

“…The lowest cost of cultivation in T 1 (100% RDF (60 kg N, 30 kg P 2 O 5 /ha)) treatment was attributed to the low cost of chemical fertilizers (urea, single superphoshate), as well as the fact that there were applied in a small quantities chemical fertilizers used in comparison to organic manures. As a result, the labour and transportation costs were declined (Singh et al (2014)). The gross returns were significantly greater with T 4 .…”

“…Although in little amounts, it can provide the plant with all the nutrients it needs. The following elements are found in farm yard manure: (0.5 %) nitrogen, (0.25 % phosphorus), (0.5 %) potassium, (0.08 %) sodium, (0.02 %) sulphur, (0.004 %) zinc, (0.0003 %) copper, (0.007 %) manganese, and (0.45 %) iron, according to research (Singh 2014).…”
