The present investigation was undertaken with an objective to assess the selection parameters and extent of heterosis in Yellow sarson (Brassica rapa var. yellow sarson). Forty F1. along with 10 lines as female and 4 testers as males were included in experimental material for generating the information. Analysis of data showed presence of wide range of variability for various characters under study. The estimates of phenotypic coefficients of variability (PCV) were found higher than genotypic coefficient of variability (GCV) and environmental coefficient of variability (ECV). Maximum heritability was recorded for seed/siliqua (94.30%), followed by seed yield per plant (90.61%) and number of primary branches/plant (84.59%) along with high genetic advance for seed yield/plant (32.34%), seed/siliqua (29.12%) and number of primary branches/plant (21.70%). For days to maturity, NDYS-2018×NDYS-113 (-12.21**), NDYS-2018 × Pusa Gold (-11.62**) and B-9 × PPS-1(-8.65**) recorded highest better parent heterosis, relative heterosis and economic heterosis respectively. NDYS-115 × Pusa Gold (-15.69**, - 15.85**) possessed highest estimates of heterobeltiosis and mid parent heterosis while NDYS-2018×NRCYS-05-01 (-9.65**) registered highest estimate of economic heterosis for plant height. For seed yield maximum heterobeltiosis and relative heterosis was observed in cross, Jhumka × NDYS-113 (52.36**, 65.34**) while NDYS-128 × PPS-1 (41.54**) was the best cross with respect to economic heterosis. The Cross, NDYS-128 × NDYS-113 (24.47**) expressed highest estimate of heterosis over better parent and maximum relative and economic heterosis was possessed by NDYS-132 × NDYS-113 (25.18**, 22.29**) respectively
For parental selection in crop development initiatives, genetic diversity knowledge is crucial. In a randomized block design, 24 French bean genotypes, including the control variety (Lakshmi), were planted in the Kharif of 2018 and their genetic differentiation for 16 cultivation traits was assessed. All of the analysed characteristics exhibited a wide range of variation in experimental outcomes. The 100-seed weight was found to have significant genotypic and phenotypic coefficient of variation (GCV and PCV), with the number of days to first harvest being the lowest. Heritability is correlated with high heritability estimates. This indicates that these traits are under additive genetic influence and are more trustworthy for efficient selection. It was found to be high for seed yield per plot and lowest for days at 50% germination. The number of days before the first harvest and the length of the fruit were positively and significantly associated with yield at both genotype and phenotypic levels, according to correlation analysis, which also showed that the rind was established at pod maturity. Genotypic pathway factor analysis revealed that the days of first flowering, days of germination, seed yield per plot, fruit length, days until first harvest, 100-seed weight, number of primary seeds, branches per plant, pod set to pod maturity, and average pod weight had the most favourable direct effects on yield per plant
Eighteen genotypes of fenugreek were evaluated for growth and yield contributing traits at the Vegetable Research Center, G.B.P.U.A. &T., Pantnagar during the year 2018-19. Analysis of variance revealed that differences among genotypes were highly significant for the characters namely, test weight, number of seeds per pod, days to 50% flowering, days to maturity and seed yield. Minimum days of 50% flowering was found in genotypes FGK131 (46 days) followed by FGK128 (47 days). Plant height ranged from 80.33cm to 111.07cm. Highest number of pods per plant were observed in genotypes FGK132 (105.63) followed by FGK134 (97.80). The highest value for seed yield were observed in genotype FGK124 (1.39 kg per plot) followed by Pant Ragini (1.36 kg per plot). Highest PCV and GCV value revealed greater phenotypic and genotypic variability among the genotypes. For the character test weight, high heritability and high genetic advance were observed.
Gentiana kurroo Royle and Swertia chirayita (Roxb.) H. Karst., commonly found in the Indian Himalayan Region have been listed into the category of critically endangered medicinal plants. Considering the important role of chlorophyll and carotenoid contents in plant’s photosynthetic ability, the present study focuses on solvent extraction methods to compare photosynthetic pigment content in G. kurroo Royle and S. Chirayita (Roxb.) H. Karst. A higher chlorophyll and carotenoid contents in S. chirayita (Roxb.) H. Karst. was observed than that of G. kurroo Royle. Extraction using DMSO and methanol showed a higher content than that with water. A variation in values was observed in both the plants as they grow at different elevations implying a difference in biochemical components of the plants and requirement of different solvents for extraction
The field experiment was carried out during the Rabi season of 2021-22 at the experimental block of the School of Agricultural Sciences of the Shri Guru Ram Rai University (SAS-SGRRU), Pathribagh, Dehradun, Uttarakhand to study the effect of various nutrient management approaches on growth, yield and net profit of wheat crop. The experiment was laid out in Randomized Complete Block Design (RBD) with eight treatments viz., Control (T1 );Vermicompost @ 5 t ha(-1+ Seed inoculation with Bijamrit + 50 % RDF (T2 ); Vermicompost @ 5 t ha-1+ PSB seed inoculation + 25 % RDF(T3 ); FYM @5 t ha-1+ PSB seed inoculation + 2 foliar spray of fermented buttermilk (T4 ); 50% RDF + FYM @5 t ha-1+ mulching @ 5 t ha-1 (T5 ); 25% RDF + Jivamrit + seed inoculation with Bijamrit + 2 foliar spray of vermiwash + 2 foliar spray of fermented buttermilk (T6 ); FYM @5 t ha-1+ Bijamrit seed inoculation + 2 foliar spray of vermiwash (T7 ) and 100 % RDF (T8 ) which were replicated 3 times. The soil of the experimental field was sandy loam with low available nitrogen and organic carbon, medium available phosphorous and available potassium Application of 50 % RDF + FYM @ 5t ha-1+ mulching has recorded more yield which is significantly higher than other nutrient management approaches. Substitution of 50 % inorganic fertilizers with FYM can be adopted for economically viable and sustainable wheat production with improved yield in irrigated conditions of Doon Valley areas of Uttarakhand
