ThesisItem Open Access Evaluation of F3 and F4 populations of HJ 513 x IS 2205 of forage sorghum for morphological & biochemical traits related to stem borer (Chilo partellus) resistance(CCSHAU, Hisar, 2021-07) Rohila, Neha; Arya, SatyawanThe present study was conducted with 200 SB lines of cross HJ 513 x IS 2205 in augmented design during Kharif 2017 and 2018 at research area of forage section, dept. of Genetics and Plant Breeding, CCS Haryana Agricultural University, to evaluate, categorize and classify them for fodder yield and stem borer resistance related traits. Observations were recorded on 23 variables involving 22 morpho-biochemical and one qualitative character. All the 200 SB lines studied exhibited wide range of mean values for all quantitative characters except leaf stem ratio. High PCV and GCV along with high heritability and genetic advance as percent of mean while in F3 & F4 population for traits viz., fodder yield per plot, dry yield per plot, stem diameter, dead heart after 35 & 45 days after emergence, stem tunneling, TSS, phenol, tanin and HCN recorded high PCV and GCV along with high heritability and genetic advance as percent of mean, PCV was higher than the GCV for all the traits denoting environmental factors influencing their expression to some degree. Correlation analysis revealed that traits viz., tannin , phenol and dry fodder yield have shown highly significant positive correlation with green fodder yield per plot while, significant correlation with green fodder yield per plot was observed with traits like crude protein, IVDMD, TSS, stem tunnelling and plant height. GFY was negatively correlated with dead heart. Genetic divergence study grouped F3 & F4 populations into 10 clusters, among which cluster VI was the largest cluster (42 SB lines), followed by clusters VIII (29 SB lines) and I (25 SB lines). In F4 population maximum number of SB lines (34) was included in cluster I followed by (32) in cluster VIII, (27). SB line 60 and SB line 96 were repeated in both year so these SB lines could be promising parents for stem borer resistance. Therefore, inter-crossing of SB lines from these diverse clusters could be suggested to generate wide range of variability, which could be improved by selection in sorghum breeding programme.ThesisItem Open Access Principal component analysis for fodder yield and its related traits in forage sorghum [Sorghum bicolor (L.) Moench](CCSHAU, 2018) Harsh Deep; Arya, SatyawanThe present investigation entitled “Principal component analysis for fodder yield and its related traits in forage sorghum [Sorghum bicolor (L.) Moench]” was carried out during Kharif season of 2017. The observations were recorded for 12 morphological (qualitative and quantitative) and eight quality parameters to assess the genetic diversity and character association in 73 forage sorghum genotypes. Analysis of variance revealed sufficient variability for all the 18 quantitative traits under study. The GCV and PCV estimates were high for plant height, green fodder yield, dry fodder yield, HCN and copper content. High heritability coupled with high genetic advance was observed for traits viz., green fodder yield, dry fodder yield, number of tillers per plant, plant height, leaf breadth, stem diameter, leaf: stem ratio, number of leaves per plant, HCN content, copper content, crude protein, TSS content, zinc content, copper content, manganese content and iron content.The Mahalanobis D2analysis grouped 73 forage sorghum genotypes into seven clusters. The inter cluster distance was observed maximum between cluster IV and cluster VII. Principal component analysis (PCA) transformed the original 18 interrelated variables into seven major principal components those explaining 69.79 per cent of total variation in the data. Varimax rotation enabled loading of all the traits on different principal factors. The first principal factor was closely associated with fodder yield and its contributing traits, whereas principal factor three and four showed high loading for quality parameters.ThesisItem Open Access Relative Efficacy of Selection Methods in Urdbean (Vigna mungo (L.) hepper)(College of Agriculture Chaudhary Charan Singh Haryana Agricultural University Hisar, 1994) Arya, Satyawan; Vashisht, R.
