Effect on intermating in early segregating population in chickpea

Journal of progressive agriculture (2014)

Vijaypal Singh N. S. Dodiya C. L. Khatik

Various conventional methods like pedigree, bulk population, mass selection, single seed descent (SSD) and single pod descent (SPD) have been used in crop improvement programme in self pollinated crops like chickpea to handle large segregating population. But these approaches of crop improvement in chickpea(Cicer arietinum L.) do not provide any opportunity for reshuffling of genes. Hence, any unfavourable associations observed in early segregating generation like in F2 are likely to persist through the F1 generations. Whereas, biparental mating in early generations like F2 help in breaking unfavourable association (Yunus and Paroda1982; Nematullah and Jha 1993). The increase in chickpea productivity through breeding efforts has not been adequate because of these traditional method following hybridization. Keeping this in view, the present investigation was planned to compute and compare the nature and magnitude of correlation among various characters in the biparental progenies and corresponding selfed generation viz. F3.

Combining ability analysis over environments in bread wheat

Electronic Journal of Plant Breeding (2019)

Vijay Sharma N. S. Dodiya R. B. Dubey S. G. Khandagale Rumana Khan

Thirty-eight genotypes of wheat including 8 parents, their 28 F1s and 2 checks evaluated in 4 different environments i.e. early sown, normal sown, late sown and very late sown conditions was undertaken to study the combining ability in bread wheat for grain yield and its component traits. From pooled analysis, it was found that mean square due to GCA and SCA were significant for all characters which revealed difference between parents for GCA and difference between crosses for SCA. Significant mean square for GCA x E and SCA x E for proline content, chlorophyll content, chlorophyll stability index and heat injury was observed. In addition, SCA x E for grain yield was also significant. This suggested that additive and non-additive genetic components were sensitive to environments. Variance for GCA was higher than their respective SCA variance for grain yield per plant, leaf canopy temperature, proline content and chlorophyll stability index which suggested that additive component was less stable over the environment than dominant component. Parents HD 2987 was good general combiners for grain yield over different environments. Cross HI 1544 x HD 2987 was the best specific combiner for grain yield per plant followed by HI 1544 x RAJ 4079.

Line X Tester Analysis for Combining Ability in Cowpea [Vigna unguiculata (L.) Walp]

International Journal of Current Microbiology and Applied Sciences (2018)

UB Pethe N. S. Dodiya SG Bhave V. V. Dalvi

This investigation on line X tester cross of 8 lines and 3 testers and their 24 crosses in Cowpea indicated the preponderance of non-additive gene action for all characters under study. The linesCPD-83 and tester GS- 9240were good general combiners for grain yield per plant and most of yield contributing characters. High SCA effect observed in the hybrids viz. H 22 (CPD -83 X PCP-97102), H 11 (CPD -31 X GS-9240) and H 2 (CPD -219 X GS-9240) for grain yield per plant (g). The characters pod length (46.61%), number of grains per pod (40.36%), and harvest index (33.21%) exhibits high heritability while remaining all characters except plant height exhibits moderate heritability.

Genetic parameters, correlation and path analysis for fodder and dual purpose sorghum [Sorghum bicolor (L.) Moench] genotypes

Range Management and Agroforestry (2024)

Dalip N. S. Dodiya Deepak Panwar Naval Singh Devra

About 60 diverse sorghum genotypes were evaluated to assess the genetic parameters, association among fodder and grain yield component traits and their direct and indirect effects on grain yield. The experiment was conducted in randomized block design at Instructional Farm, Department of Genetics and Plant Breeding, Rajasthan College of Agriculture (MPUAT), Udaipur in collaboration with AICRP on Sorghum. Analysis of variance revealed highly significant differences among the genotypes for all 14 traits studied. In the present investigation range of the magnitudes of all genetic parameters for each trait was classified based on mean and standard deviation (SD) into three categories viz., high (> ), medium (in between ) and low (< ). Traits viz., total soluble solids (%), grain yield per plant (g), leaf breadth (cm) and dry fodder yield per plant (g) were the most approachable for selection as they had higher GCV, PCV, genetic gain and moderate to high heritability in a broad sense. Hence, simple selection could be effective for further improvement of these characters. Based on correlation and path analysis, the traits, dry fodder yield per plant, harvest index, green fodder yield per plant, leaf breadth, protein content and plant height might be considered as indirect selection indices for improvement in grain and fodder yields of sorghum.

N. S. Dodiya C. L. Khatik P. Rokadia

Six parents and their all possible crosses (excluding reciprocals) of desi chickpea were grown at experimental farm of Plant Breeding and Genetics, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur (Rajasthan). This experiment was conducted in random block design with three replication and estimate heterosis for 11 yield and yield related traits. The experimental result for heterosis revealed that out of 15 hybrids, seven hybrids recorded significant positive heterosis for yield per plant, five and eleven hybrids recorded significant positive heterobeltiosis and economic heterosis for yield per plant, respectively. The cross KWR-l08 X DCP-92-3 showed the highest magnitude of heterosis and heterbeltiosis for yield per plant, biological yield and 100 grain weight. The cross IPC-94-19 X IPC-94-94 showed highest significant positive economic heterosis for yield perplant, biological yield and pod per plant.

Genetic variability and Path Analysis in Opium Poppy (Papaver somniferum L.)

International Journal of Current Microbiology and Applied Sciences (2017)

Santra Haritwal N. S. Dodiya C. L. Khatik

A field experiment was conducted during rabi season of 2016-17 at Research Farm, Rajasthan College of Agriculture, MPUAT, Udaipur to study “ Genetic Variability and Path Analysis in Opium poppy (Papaver somniferum L.)” was carried out using 25 genotypes were planted in randomized block design including 2 checks. The data obtained were subjected to analysis of variance, estimation of different variability parameters and path coefficient analysis. The observations were recorded on five randomly selected plants for twelve characters. Analysis of variance revealed significant differences among the genotypes for all the characters suggesting sufficient amount of variability in the experimental material under study. High GCV coupled with high heritability and expected genetic gain of a character provides good selection advantage. There is a substantial scope for improvement of seed yield per plant, harvest index for latex yield and husk yield per plant. Selection for these characters would be effective in selection of suitable genotype for opium poppy improvement. Path coefficient analysis revealed that husk yield per plant, number of effective capsule per plant, diameter of main capsule, days to 50 per cent flowering, plant height and was the major components for seed yield per plant and latex yield per plant respectively because these traits had maximum direct and indirect effect towards seed yield and latex yield. The estimate of phenotypic coefficient of variance was higher in magnitude than the respective genotypic coefficient of variance for all the characters indicating the important role of environment in the expression of characters. Chetek Aphim (0.16 g), UOP 121 (0.15g/plant), UOP 30 (0.14g/plant) and UOP 53(0.13g/plant) were found superior for latex yield and genotype UOP 53 (7.52 g/plant), UOP 150 (6.41 g/plant) and JOP 540 (6.31g/plant) for seed yield. The genotype UOP-53 found superior for both latex and seed yield per plant.

Variability, Character Associations and Path Analysis in Ashwagandha (Withania somnifera (L). Dunal) with Respect to Root Yield and Biochemical Aspects

Annals of biological research (2017)

Gopal Singh N. S. Dodiya Arunabh Joshi C. L. Khatik

Background: The experimental study was carried out to know the genetic variability, characters association, interrelationship and cause and effect of various characters in ashwagandha with respect to dry root yield and biochemical aspects. Methods: Twenty genotypes (including 3 checks) were evaluated for 13 traits (10 quantitative and 3 qualitative) and analysis of variance, correlation and path analysis were performed for the mean data. Results: All characters were found to be differing significantly among genotypes. Estimates of variability parameters revealed that a high genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were found for total antioxidants content in root, dry root weight per plant, dry plant weight per plant and harvest index (%). High heritability (h2) was found for total crude fiber content in root, total antioxidants content in root, plant height and number of secondary branches per plant. Total antioxidants content in root, dry plant weight and total crude fiber content in root were recorded with high genetic advance (GA). A high heritability coupled with high genetic advance was found for total antioxidants and total crude fiber content in root. Root diameter, plant height, dry plant weight and days to 75% maturity were shown significant positive correlation with dry root yield per plant. Path coefficient analysis revealed that root diameter, days to75% maturity and plant height had shown high positive and direct effect on dry root yield per plant. Conclusion: The heritable variability and estimates of variability can be used for crop improvement. Root diameter, days to 75% maturity, plant height and dry plant weight could be used to select high dry root yielding genotypes. Biochemical data (alkaloid and antioxidants content) will be useful to select genotypes of high medicinal value.

Combining ability analysis in bread wheat (Triticum aestivum (L.) Em. Thell) under different environmental conditions

Bangladesh Journal of Botany (2019)

Vijay Sharma N. S. Dodiya R. B. Dubey Rumana Khan

Pooled analysis of 8 genotypes of wheat of diverse origin, their 28 F1s and 2 checks was carried out in 4 different environments to study the combining ability in bread wheat for grain yield and its component traits. On pooled basis, analysis of variance due to GCA and SCA was significant for all characters revealed difference between parents for GCA and difference between crosses for SCA. Similarly, mean square due to GCA × E was significant for number of effective tillers per plant and flag leaf area revealed influence of environment on GCA. Whereas SCA × E was also significant for number of effective tillers per plant and grain yield per plant revealed influence of environment on SCA. The variance due to GCA was higher than their respective SCA for all characters except number of grains per spike indicating that additive type of gene action played role in the expression of all these traits. Significant GCA effects for grain yield and its component traits were exhibited by the parents HD 2987, Lok 1 and HI 1544. Fourteen crosses recorded showed significant SCA effects for grain yield and related traits.

Journal of Medicinal and Aromatic Plant Sciences (2017)

CL KHATIK SP SHARMA N. S. Dodiya SR MALOO Arvind K. Joshi

Combining ability studies for eight parents and their all possible crosses (excluding reciprocals) in opium poppy were carried out at experimental farm of Plant Breeding and Genetics, Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur (Rajasthan). The experiment was conducted in a random block design with three replications and estimated the combining ability for latex yield and yield related traits. Combining ability analysis indicated that mean square due to gca and sca were significant for all the characters, expect for plant height for sca, indicating the importance of both additive as well as nonadditive genetic effect for the inheritance of all the characters under pooled over environments. Parents UOP-69, UOP-80 and UOP-99 were good combiners for most of the important characters specially latex yield per plant,seed yield per plant, effective capsules per plant, seed harvest index and morphine content in pooled over the environments. The parent UOP-53 was also good combiner for morphine content. The parent UOP-79 possessed good nicking ability for earliness and short plant stature. On pooled basis, the hybrids UOP-80 x UOP-20, UOP-53 x UOP-1185, UOP-79 x UOP-60, UOP-79 x UOP-20, UOP-79 x UOP-1185 UOP-80 x UOP-1185 also showed high SCA effect for latex, seed and husk yield per plant. The obtained data can be used for exploitation of heterosis for latex yield potential and other related traits.
