ThesisItem Open Access Molecular and Morphological studies in F5 generation of wheat derived from WH 711 and PBW 698 for Yellow rust resistance(CCSHAU, Hisar, 2020-08) Mohammadi, Lina; Mukesh KumarThesisItem Open Access Heterosis and combining ability analysis for yield and fiber quality traits in American cotton (Gossypium hirsutum L.)(CCSHAU, Hisar, 2020-01) Chakholoma, Maggie; SomveerThe present study was carried out during Kharif season of 2018. The experimental material comprised of 12 lines viz., H 1471, H 1472, H 1480, H 1488, H 1489, H 1508, H 1518, H 1519, H 1520, H 1522, H 1523, H 1098i and 4 testers viz., C 201, C 202, C 210, C 211 and 48 crosses generated by crossing 12 lines with 4 testers in Line x tester design and one standard check hybrid HHH 223. The objective of the study was to determine heterosis of hybrids, combining ability and variances for different traits and identify the best combiners with respect to seed cotton yield and fibre quality. Observations were recorded for 14 characters namely, days to 1st flower, plant height (cm), number of monopods/ number of sympods per plant, number of bolls/plant, bolls weight (g), seed index (g), ginning out turn (%),) lint index, seed cotton yield per plant (g), uniformity index, fibre strength, upper half mean length and micronaire value. Ten crosses recorded a magnitude of heterosis for seed cotton yield per plant of above 40 percent. The highest economic heterosis for seed cotton yield was observed by the cross H 1489 x C 210 which also exhibited highest per se performance and significant sca effects for important characters; number of bolls per plant and boll weight. The variance gca/sca ratio depicted predominance of non-additive gene action for days to first flowering, number of bolls per plant, boll weight, seed index, seed cotton yield per plant, fibre strength, uniformity ratio, upper half mean length and micronaire value. The characters lint index, and number of monopods per plant revealed non- additive and additive gene action while plant height, number of sympods per plant and GOT were pre dominantly controlled by additive gene action. The lines H 1471, H 1472 H 1480 and H 1518 and the tester C-201 were found to be the best combiners and be considered for future breeding programme. The cross combination H 1480 × C 201 recorded highest significant SCA effects for seed cotton yield per plant and also exhibited significant economic heterosis for important characters. H 1098i × C 211 recorded significant SCA effects and economic heterosis for seed cotton yield. Hence, should be considered for further testing over location and environments.ThesisItem Open Access Genetics of morpho-phenological characters and seed yield in fieldpea (Pisum sativum L.)(CCSHAU, Hisar, 2020-08) Kamboj, Seema; RavikaSix generations (P1, P2, F1, F2, B1 and B2) obtained from two crosses (GP 02/1108 x HFP 920 and GP 02/1108 x HFP 9907B) involving three genetically diverse dwarf, medium and tall parents were studied to find out the inheritance of seed yield and morpho-phenological characters in fieldpea. Generation means exhibited presence of sufficient variability for almost all the traits. Individual Scaling tests and Joint Scaling test failed to explain the additive-dominance model for all the characters except number of primary branches revealing presence of epistatic interactions. All the three types of epistasis were observed through six parameter model. It also revealed presence of fixable component, though lesser than non fixable component, for majority of characters. High heritability with high genetic advance was observed for inter-nodal distance, height of first reproductive node, plant height, number of seeds per pod and biological yield per plant in both the crosses. Seed yield per plant exhibited positive correlation with number of primary branches, number of nodes, 100-seed weight, number of pods and harvest index and negative with days to flowering, inter-nodal distance, height of first reproductive node and plant height. The plant height was observed to have significant positive association with days to flowering, inter-nodal distance, height of first reproductive node, number of seeds and biological yield and negative association with number of secondary branches, number of nodes, number of pods and seed yield. Positive direct effect on seed yield was observed to be highest of number of pods followed by number of nodes, 100-seed weight, number of primary branches and harvest index whereas negative was observed highest of plant height followed by height of first reproductive node, inter-nodal distance and days to flowering. 100-seed weight, number of pods and primary branches exhibited high indirect effect on seed yield through various traits. Hybridization involving dwarf parent resulted into reduction in plant height, internodal distance and biological yield and increased number of primary branches per plant, number of secondary branches per plant and number of pods per plant. Sufficient fixable component for the traits envisaged practicing pedigree method. However, to exploit additive as well as non-additive gene effects simultaneously breeding methods like selection from delayed generations and bi-parental mating approach are advocated.ThesisItem Open Access Characterization and evaluation of wheat accessions for drought tolerance using morpho-physiological traits(CCSHAU, Hisar, 2020-08) Parul; Bishnoi, O.PThe objectives of present investigation were to determine the genetic variability, estimation of association between grain yield and its component traits and among themselves to find out the correlation with morpho-physiological traits of 40 genotypes of wheat under drought and irrigated condition. Significant variability was observed among genotypes for all the traits under both conditions. Genotypes WH1127, DPW621-50 for grain yield while C306 and WH1164 for biological yield per plant were found promising under both environmental conditions. Grain yield per plant showed highly significant and positive correlation with biological yield per plant, harvest index, effective tillers per plant and 1000-grains weight. The path coefficient analysis revealed that harvest index showed highest direct and positive effect on grain yield per plant followed by biological yield per plant. Genotype IC529189 showed better expression for NDVI, C.T, SPAD under drought condition while under irrigated condition, maximum value for NDVI was shown by genotype IC529909 and for SPAD genotype IC529189. Based on SSI it was found that genotype EC609575, DT25, IC539518, IC529429 were more resistant to drought. Genotypes which resulted in the expression of higher grain yield would be selected.ThesisItem Open Access Genetic variability studies and screening for blast resistance in pearl millet [Pennisetum glaucum (L.) R. Br.](CCSHAU, Hisar, 2020) Dhukia, Mohit; Dev VartThe present study entitled, “Genetic variability studies and screening for blast resistance in pearl millet [Pennisetum glaucum (L.) R. Br.]” comprised of 100 pearl millet genotypes (50 designated A/B lines, 41 R lines and nine hybrids) and was laid out in two replications in randomized block design at experimental field of Bajra section, CCS HAU, Hisar during kharif (Rainy) 2019. Mean sum of squares were found to be highly significant due to genotypes for all the characters studied. The traits viz., panicle diameter, plant height, 1000-seed weight, dry fodder yield per plant and grain yield per plant exhibited high estimates of GCV, PCV, heritability and genetic advance as per cent of mean. Significant positive correlations were observed for grain yield per plant with plant height, panicle diameter, panicle length, 1000-seed weight and dry fodder yield per plant while with days to 50% flowering and blast it was negatively and significantly correlated. According to path coefficients analysis, high direct contribution towards the grain yield per plant was revealed by the traits viz., number of productive tillers per plant and panicle diameter. As per the blast screening studies, a total of 57 genotypes were found resistant towards the disease and male parent seems to have a major contribution in resistant towards the blast infection.ThesisItem Open Access Study on genetic divergence and character association for yield and its contributing characters in faba bean (Vicia faba L.) genotypes(CCSHAU,HiSAR, 2020) Chaurasia, Harsh; Rajesh KumarThe present investigation consist of 53 genotypes of faba bean that were assess from various source and raised in RBD design with 3 replication in the rabi season of 2019-20 at Research Farm of MAP Crop Section of Department of GPB, CCS HAU, Hisar with the objective of assessment of the genetic variability, heritability and genetic divergence of seed yield and its contributing characters. The results of analysis of variance indicated that the substantial genetic variability were present for seed yield and its contributing characters. The estimates of PCV had higher in magnitude than that of respective estimates of GCV, which suggested that the environmental factor were also influencing the expression of the genotypes. The combined analysis of correlation coefficient analysis and path coefficient analysis revealed that the characters, namely, no. of pods cluster per plant, no. of branches per plant, no. of pods per plant, no. of pods per cluster, no. of seeds per pod, 100 seeds weight, pod yield per plant, biological yield and harvest index were the major seed attributing characters and hence; emphasis should be given to this characters while programming any plant breeding programme. The 53 genotypes were grouped into 6 clusters using Tocher’s method. The maximum intra- cluster D2 value was recorded for cluster no. 4, which suggested that the cluster no. 4 had maximum genetic heterogeneity among the genotypes presented in this cluster, whereas, the maximum inter- cluster D2 value was recorded for cluster no. 5 and cluster no. 6 which indicated that the genotypes present in these two clusters had highest genetic diversity. The genotypes namely EC-32905, EC-243036, EC- 591784, HB-03, HB-19, HB-61 and Vikrant are selected on the basis of their mean performance for different characters.ThesisItem Open Access Genetic diversity studies for various agro-morphological traits and blast severity in pearl millet [Pennisetum glaucum (l.) R.Br.](CCSHAU,HiSAR, 2020-09) War War Lin Aung; Pahuja, S.KThe study was conducted to assess the magnitude of genetic diversity and variability among pearl millet genotypes involving 50 genotypes were planted in a RBD design during kharif 2019 at the Bajra Research Area of Department of Genetics and Plant Breeding, Chaudhary Charan Singh Haryana Agricultural University, Hisar. Crop yield is the result of the interaction of number of other, often interrelated attributes. However, negative correlations of blast severity at 30 days and 60 days with grain yield per plant and most of other characters indicated that increase in blast severity at 30 as well as 60 days will decrease grain yield per plant as well as most of the other yield related traits significantly. An obvious association of a trait to the yield might be appearing, due to balancing of positive and negative contribution. Therefore, path coefficient analysis could be more effective method for use in selection programmme, mainly on component breeding. Based on the ongoing discussion, the traits viz.,1000-seed weight, dry fodder yield per plant, days to 50% flowering, panicle length and productive tiller per plant may be given due attention in pearl millet breeding. Using Mahalanobis‟s D² statistics, among the five clusters, cluster I was the largest with 20 genotypes, followed by cluster III (12 genotypes), cluster IV (9 genotypes) , cluster V (6 genotypes) and cluster II (3 genotypes). Inter cluster distances were higher than the intra cluster distances indicating the presence of wider genetic diversity between the clusters rather than within the clusters. More inter cluster distance suggests that the genotypes belonging to these clusters if chosen for hybridization programme, will give highly heterotic hybrids and broad spectrum of variability in subsequent segregating generations. The pearl millet genotypes were screened for blast disease reaction under natural field condition. The management of the disease through host plant resistance has been the best choice in all the crops. The study revealed that 29 were found as resistant viz., SGP-10-107, EBC-12/237, HB-15/085, H-13/0001, EMRC-14/123, EMRCT-14/121, S-19-499-504(61), S-19-505-510(96), EMRCT-14/107, S-19-547-570(65), EMRCT-14/237, HTP-93/109-1, TCH-26-1, S-19-573-574, EMRCT-15/133, PRCT-115, PRCT-117, PRCT-132, AC-04/13, S-19-575-576, S-19-579-580, IH-8, PRCT-101, PRCT-112, S-19-517-522(130), EMRCT-14/103, EMRCT-14/243, S-19-577-578, PRCT-121 and twenty (20) genotypes were moderately resistant. However, one genotype was found susceptible. The 29 blast resistant genotypes found in the present study may be further tested and utilized in blast resistant breeding programme.ThesisItem Open Access Morpho-physiological and SSR markers studies on terminal heat tolerance in bread wheat (Triticum aestivum L. em. Thell)(CCSHAU,HiSAR, 2020) Redhu, Mandeep; Vikram SinghIn the present investigation, 200 recombinant inbred lines (RILs) of the cross WH711/WH1021 were grown in randomized block design at CCSHAU, Hisar, during Rabi 2018-19 under timely sown and late sown conditions. The substantial amount of genetic variability was observed for all the traits. The traits such as CTD 2, total antioxidant activity, transpiration rate, photosynthetic rate and number of effective tillers per meter showed high GCV, PCV, heritability and genetic advance under both conditions. The grain yield per plot showed a positive and significant correlation with grain filling duration, number of effective tillers per meter, spike length, number of spikelets per spike, number of grains per spike, biological yield per plot, harvest index, 1000 grain weight, seed density, NDVI 1, NDVI 2, CTD 1, CTD 2, SPAD 1, SPAD 2, relative water content, total antioxidant activity, stomatal conductance, transpiration rate and photosynthetic rate under both environments. Heat stress indices were estimated to find out heat tolerance among RILs. Grain yield/plot showed a positive correlation with STI, MP, GMP, HM, MRP, while HSI, TOL, SSI and RED showed negative correlation with grain yield/plot under stress conditions. The path analysis revealed that biological yield per plot, harvest index, 1000 grain weight and number of effective tillers per meter were main contributor towards grain yield per plot. Regression analysis demonstrated variability for grain yield per plot was due to biological yield per plot, harvest index, seed density, CTD 1 and SPAD 1. The principal component analysis for morphological traits, physiological traits and heat stress indices indicated that the first two components accounted for more than 42%, 85% and 89% of the total variance, respectively. Based on euclidean cluster analysis, RILs were grouped into nine and eight clusters, cluster IX and cluster VIII were identified most divergent as well as high mean values for most of the traits. Composite interval mapping (CIM) identified a total of 14 QTLs, i.e. 6 for morphological traits, 1 for physiological traits and 7 for heat stress indices.ThesisItem Open Access Characterization of pearl millet [Pennisetum glaucum (L.) R. Br.] germplasm for agronomic and nutritional traits under rainfed condition(CCSHAU, Hisar, 2020-07) Vinay Kumar; Dehinwal, Ashok KumarThe present investigation entitled “Characterization of pearl millet [Pennisetum glaucum (L.) R. Br.] germplasm for yield and nutritional traits under rainfed condition” was carried out to study extent of genetic variability in different morphological and biochemical traits and their association with yield and nutritional traits in pearl millet germplasm. Mean sum of squares due to treatments were highly significant for all the traits under study, indicating that considerable amount of variability was present among the genotypes for all the traits. High GCV, PCV, heritability and genetic advance as % of mean was observed for the traits viz., panicle length, panicle diameter, productive tillers (no. /plant), fodder yield per plant, 1000 seed weight and grain yield per plant indicating predominance of additive gene action. Hence, resorting to simple selection would be effective. The combined analysis of correlation coefficient analysis and path coefficient analysis revealed that the traits, mainly, dry fodder yield, plant height, panicle diameter, number of productive tillers per plant and calcium content were the major yield attributing traits and hence; emphasis should be given to this traits while programming any plant breeding programme. No significant associations were observed between the nutritional traits and grain yield, indicating that there should be no compromise on grain yield while selecting for high nutritional content genotypes in pearl millet breeding programmes.
