    Variability, character association and genetic divergence studies in Indian mustard (Brassica juncea L. Czern and Coss.)
    (ANDUAT, Kumarganj, Ayodhya, 2021-07) Patel, Amarjeet; Verma, O.P.
    The present investigation entitled “Variability, characters association and genetic divergence studies in Indian mustard (Brassica juncea L. Czern and Coss.)” involving 40 genotypes was undertaken to examine the (i) variability for seed yield and its contributing traits, (ii) character association among different characters, (iii) direct and indirect effects of yield components on seed yield per plant and (iv) genetic divergence using D² analysis in the Indian mustard genotypes. The experiment was conducted at Students Instructional Research Farm at Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during rabi, 2020-21. All the 40 Indian mustard genotypes were tested in Randomized Block Design with three replications. Observations were recorded on 12 quantitative characters namely, days to 50% flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, length of main raceme (cm), number of siliquae on main raceme, number of seeds per siliqua, 1000-seed weight (g), harvest index (%) and seed yield per plant (g). Analysis of variance observed substantial amount of variability among the genotypes for all the characters, under study, found wide spectrum of variability among the genotypes. Phenotypic correlation was of higher magnitude as compare to their corresponding genotypic correlation. Among genotypes correlation the seed yield was having positively and significantly correlated with biological yield per plant (0.870) followed by harvest index (0.609), number of secondary branches per plant (0.342) and number of siliquae on main raceme. While positive non-significant correlation with days to maturity (0.132) followed by number of seed per siliquae (0.066) plant height (0.052) and days to 50% flowering (0.046). As a result, any selection based on these characters will increase the performance and quality of Indian mustard. Path coefficient analysis showed that biological yield per plant, harvest index, number of primary branches per plant, number of siliquae on main raceme, days to maturity and number seed per siliquae were the most important character, controlling positive directly to seed yield. Mahalnobis D2 genetic divergence the non- hierarchical Euclidean cluster analysis grouped 40 genotypes into 7 clusters. These indicated the existence of high degree of genetic diversity in the germplasm.

    (ANDUAT, Kumarganj, Ayodhya, 2021-07-27) Singh, Aman; Singh, Dr. R.K.
    The present investigation entitled “Genetic divergence analysis and character association in different genotypes of wheat (Triticum aestivum L.)” conducted on 94 accessions of wheat during 2019-20 at Main Experiment Station (MES) of A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) to evaluate genetic divergence and character association for the identification of most diverse and promising genotypes. The experiment was laid out in Augmented Block Design. The observations were recorded on various morphological and physiological characters. The wide range of variation for different characters and comparison of means of germplasm line indicating existence of very high degree of variability for peduncle length, flag leaf area, biological yield plant-1, grain yield plant-1, 1000 – grain weight and harvest Index which could be utilized for breeding for improvement in the indigenous lines of wheat. Positive and significant correlation between tillers plant-1, spike length, biological yield plant-1, 1000-grain weight and harvest index. Path analysis revealed that maximum positive direct effect on grain yield plant-1 was exerted by the biological yield plant-1 followed by harvest index and flag leaf area. Field experiment based non-hierarchical Euclidean clustering for eleven physiological traits for 94 genotypes shows the maximum inter – cluster distance between cluster IV and VII followed by cluster IV and VI and cluster II and VII. The maximum intra – cluster distance was observed in cluster X followed by cluster IX and cluster V.

    Studies on Character Association and Genetic Divergence in Wheat (Triticum aestivum L.) under Sodic Soil Condition
    (ANDUAT, Kumarganj, Ayodhya, 2021-07-27) Singh, Sudhanshu; Singh, Dr. Vinod
    The present investigation entitled “Studies on CharacterAssociation and Genetic Divergence in Wheat (Triticum aestivum L.) under Sodic Soil Condition” was conducted at Main ExperimentStation (MES) of A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during Rabi,2019-20. 105 genotype of bread wheat along with four checks. The experimentwas laid out in Augmented Block Design. The whole experimental field was divided into 7 blocks of equal sizeand every block had 19 plots of test entries along with 4 checks. The characters studied were days to 50%flowering, days to maturity, plant height, number of productive tillers per plant, peduncle length, spike length, number of grain per spike, test weight/1000-grain weight, grain yield per plant,biological yield per plant and harvest index. The assessment of existing variability within the 105 variety along with4 checks, collections was done by computing means, range, correlations, path-coefficients, heritability, geneticadvance andgenetic divergence. The wide range of variation for various characters and comparison of means of germplasm lines indicated the existence of very high degree of variability for all the characters within the 109 germplasm lines of wheat. Thevariety SATSN-18 (15.64 g) and SATSN-27 (15.64) produced highest grain yield per plant followed by SATSN-16 (15.28), SATSN-C29 (15.26), and SATSN-N24 (15.28). These lines also possessed average to high mean performance for many of the yield components. Therefore, these entries were identified as most promising varieties/lines to be used in hybridization programme as a donor parents. The lowest and highest mean performances for biological yield/ plant were recorded by SATSN-N10 and FLW-3, respectively. Thevery best positive direct effect on grain yield/plant was exerted by harvest-index, followed by biological yield/plant, days to 50% flowering, plant height showed positive direct effect on grain yield. The characters showing highly significant positive correlation among yield and its components suggested that in selection these characters could also be given due emphasis for developing high yielding varieties. Grains/spike has the highly significant correlation with the days to 50% flowering. The path analysis identified the major direct effect on grain yield per plant by biological yield per plant followed by harvest index, spikelets per spike, days to 50% flowering, test weight, plant height and tillers per plant. While plant height, spike length, days to maturity, number of grains per spike, tillers per plant, peduncle length, spikelets per spike, tillers per plant and peduncle length are emerged as most important indirect yield components.
