Salinity Stress Tolerance

The present study was carried out to generate some information on the genetic basis for salinity tolerance in chickpea. Results indicated that the additive as well as non-additive gene action was important for all the traits under unstressed as well as salinity stress condition. Parent Pusa 1103 was a good combiner for RWC, MSI, seed yield and harvest index both under unstressed and salinity stress condition. DG 72 was a good combiner for RWC and parent SAKI 9516 for days to maturity both under unstressed and salinity stress. Two crosses Pusa 1103 x DG 72 and cross Pusa 1103 x DG 54 were best among all the crosses studied for seed yield per plant. While selecting best crosses for salinity stress tolerance besides giving more importance to salinity indices the seed yield per plant need to be considered. The present findings will help the chickpea breeder in deciding the breeding program aimed at improvement of salinity stress tolerant varieties in chickpea.

The present investigation consists of   26 genotypes of Chickpea including one check, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant Breeding, SHUATS, Prayagraj during Rabi 2020 following RBD with three replications. The data were recorded on 11 characters. Assessment of genetic variability, cause effect and interrelationship among yield components in chickpea. High significant variation was obtained for all characters studied. High GCV and PCV in chickpea germplasm were observed for Total no of pods per plant, number of effective pods per plant, biological yield, seed yield. High estimate of heritability coupled with high genetic advance as percent of mean was recorded for No. of primary branches, No. of secondary branches, Total no of pods per plant, No. of effective pods per plant, biological yield, Seed yield per plant, Harvest index, Seed index. High values for heritability indicates that it may be due to higher contribution of genotypic components. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively. Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant association with Biological yield per plant, Harvest index and plant height at genotypic and phenotypic levels. Correlation coefficient analysis revealed that seed yield per plant exhibited positive and significant association with Biological yield per plant, Harvest index and plant height at genotypic and phenotypic levels. Path analysis revealed that characters plant height, number of primary branches, biological yield and harvest index have positive direct effect on seed yield per plant at genotypic and phenotypic level.

The present study was conducted in the experimental farm, Sher-e-Bangla Agricultural University (SAU), Dhaka during July 2013-December2013. The analysis of variance revealed significant deviation for all the characters studied and indicated the existence of variation among thegenotypes. The PCV values were slightly higher than the respective GCV values for all the characters except unfilled grains per panicleindicating that the characters were less influenced by the environment. Total tillers per plant, effective tillers per plant, filled grains per panicle,unfilled grains per panicle and yield per plant showed high heritability coupled with high genetic advance percentage of mean which indicatedthe preponderance of additive gene action and such characters could be improved through selection. High heritability along with low geneticadvance as percentage of mean was found for plant height, days to 50% flowering, panicle length, days to maturity and thousand grains weightwhich indicated the non additive gene action for expression of these characters. Considering the genetic parameters and other agronomicperformances, the genotypes Special from AL-29, AL-36, PP-4B(i), AL-17(iii)B, AL-17(iii), AL-17(ii)A, Special from-129, Special from17(iv), AL-44(i), AL-17, Special from AL-36(D), PP-48, IR-25B, Special from AL-33, IR-25B (Tall), P-5B (ii) might be considered betterparents for future hybridization programme.DOI: http://dx.doi.org/10.3126/ijasbt.v3i1.11896    Int J Appl Sci Biotechnol, Vol. 3(1): 73-79

Mutations were induced in three chickpea genotypes, ICC-15936, BRC-1104-127 and C-108 using sodium azide (SA) as a mutagen. The immediate effects of mutagenic treatments were measured in terms of biological damage caused in M1 generation. All the mutagenic treatments brought reduction in seed germination, seedling length and plant survival. Such reduction, with an exception of plant survival, were found to be depended upon the dosage of the concentration.High GCV and PCV in chickpea germplasm were observed for number of effective pods per plant, number of secondary branches per plant, number of pods per plant, seed yield per plant, plant height, number of primary branches per plant, seed index, harvest index, biological yield per plant. High estimate of heritability coupled with high genetic advance as percent of mean was recorded for number of effective pods per plant, number of secondary branches, number of pods per plant and seed yield per plant. High values for heritability indicates that it maybe due to higher contribution of genotypic components. Traits exhibiting high heritability coupled with genetic advance as percent of mean suggest that the traits are governed by additive gene action, equal contribution of additive and non-additive gene action respectively.

<p>The knowledge of genetic action, heritability and genetic variability is useful and permits plant breeder to design efficient breeding strategies in soybean.  The objectives of this study were to determine gene action, genetic variability, heritability and genetic advance of quantitative characters that could be realized through selection of segregation progenies. The F1 population and F2 progenies of six crosses among five soybean varieties were evaluated at Muneng Experimental Station, East Java during the dry season of 2014.  The lines were planted in a randomized block design with four replications.  The seeds of each F1 and F2 progenies and parents were planted in four rows of 3 m long, 40 cm x 20 cm plant spacing, one plant per hill. The result showed that pod number per plant, seed yield, plant yield and harvest index were found to be predominantly controlled by additive gene effects.  Seed size was also controlled by additive gene effects, with small seed dominant to large seed size.  Plant height was found to be controlled by both additive and nonadditive gene effects.  Similarly, days to maturity was due mainly to additive and nonadditive gene effects, with earliness dominant to lateness.  Days to maturity had the highest heritability estimates of 49.3%, followed by seed size (47.0%), harvest index (45.8%), and pod number per plant (45.5%).  Therefore, they could be used in the selection of a high yielding soybean genotype in the F3 generation. </p>

Genetic parameters, variability, heritability and genetic advance were studied among 20 genotypes of chickpea during during Rabi 2012-13. The characters, seed yield per plant and 100-seed weight had high values of GCV, heritability and GAM and were found to be under greater control of additive gene action. While the traits, primary branches per plant, number of seeds per pod and protein content with moderate to low heritability coupled with low genetic advance appear to be more affected by on non-additive gene action. Correlation and path coefficient analysis for seed yield per plant and its components indicated that out of 11 characters, seed yield per plant showed significant and positive correlation with harvest index, number of seeds per pod, primary branches per plant, number of pods per plant, biomass per plant, and 100-seed weight indicating that an intense selection for these characters will improve seed yield in chickpea. Path coefficient analysis revealed that days to maturity, primary branches per plant, biomass per plant, harvest index, protein content and number of seeds per pod were major characters influencing seed yield directly and indirectly. The results indicated that number of seeds per pod should be given greater emphasis for manipulation of seed yield in chickpea.

Five crosses were evaluated to study the extent of heterosis and inbreeding depression for yield and its attributing traits in greengram. Heterosis over mid parent, better parent and standard variety was significant for pods/plant and seed yield/plant. The crosses exhibiting high heterosis also expressed high inbreeding depression for pods/plant, pods/cluster and seed yield/plant. Heterosis coupled with inbreeding depression revealed the predominance of non-additive gene action for most of the characters studied. Owing to its autogamous genetic architecture and biological constrains of the crop the heterosis could be exploited only by isolating the desirable segregants for yield attributes adopting bi-parental or recurrent selection in early segregating generations followed by single plant selection in subsequent generations.

A field experiment was conducted to know the gene action and selection of superior parents of velvet bean for hybridization. The heterosis and combining ability study was carried out using 6x6 half diallel mating design excluding reciprocals. Combining ability analysis revealed that magnitude of sca variance was greater than gca variance suggesting the predominance of non additive gene action for most of the traits except days to 50 per cent flowering, number of flowers per inflorescence, number of pods per bunch and 100 seed weight where gca variance was greater than sca variance indicating predominance of additive gene action. Based on gca effects, parents Arka Dhanwantari, IIHR Selection 8 and IIHR Selection 2 were best general combiners for the traits such as number of flowers per inflorescence, pod length, pod weight, number of bunches per plant, number of pods per bunch, dry pod yield and seed yield per plant which can be used in future breeding programme. Specific combining ability studies indicated cross IIHR Selection 2 x IIHR Selection 8 as best specific combiner for the economically important traits viz., pod length, pod weight, dry pod yield per plant and seed yield per plant. The cross IIHR Selection 8 x IIHR Selection 3 was recorded high heterotic effects for dry pod yield per plant, seed yield per plant and test weight of the seed. The cross IIHR Selection 2 x IIHR Selection 8 as superior hybrid as recorded high heterobeltiosis for days to 50% flowering, pod length, pod weight, dry pod yield per plant and seed yield per plant and days to maturity which can be exploited in future breeding programme.

Twenty eight hybrids developed by utilizing eight parents in 8 x 8 diallel mating design excluding reciprocals were evaluated in randomized block design with three replications for twelve characters in order to understand the combining ability and gene action in pigeonpea. The analysis of variance for combining ability revealed presence of additive and non- additive gene action. The ratio of gca/sca variance was less than unity which indicated the preponderance of non- additive gene action for action in the control of pod length, harvest index, protein content and leaf area. The estimates of general combining ability suggested that parents ICPL-87119, GT-103 and AGT-2 were good general combiners for seed yield per plant and its attributing characters while, hybrids UPAS-120 x GT-103, BSMR-853 x BANAS and BSMR-853 x GT-1 showed the higher order sca effect for seed yield per plant. These cross combinations can be potentially utilized in hybrid breeding programmes.

<p>Genetic parameters of a character, which is estimated using genetic analysis approach, is important in a character improvement. The aim of this research was to examine the gene action of days to maturity character on soybean using generation mean analysis. The research consisted two steps, first was preparing four populations (F1, BC1.1, BC1.2 and F2) of three single crosses, i.e. Nanti × Grobogan, Grobogan × Malabar, and Nanti × Malabar. The second step was testing those populations consisting of P1, P2, F1, F2, BC1.1 and BC1.2 in the field at Jambegede Experimental Station, Malang, East Java, from July to September 2009. The results showed that there were interaction between the gene loci on the inheritance of days to maturity, from the three cross combinations under study. The role of additive gene action and the influence of dominant inheritance contributed jointly, affecting days to maturity of early maturity (Grobogan) and early maturity (Malabar) cross. The crossing of very late maturity (Nanti) with early maturity (Grobogan or Malabar) showed that early maturity was probably controlled by additive recessive genes.</p>

An investigation to study of combining ability and gene action was conducted on green gram for seed yield per plant and its component traits. For this study, line x tester design of mating was used taking six genotypes as lines and four genotypes as testers. The variance analysis revealed significant differences for different sources of variation for most of the traits. The higher specific combining ability (SCA) values were compared to general combining ability (GCA) values. The higher degree of dominance indicated preponderance of non additive gene action. The dominance variance was predominant for all the characters except for pods per plant indicating the major role of non-additive gene action and it was highest for harvest index (HI) followed by plant height and days to 50% flowering. The parents, viz., BM 4 and JM 721 among line and AKM 8802 among testers exhibited positive significant effects and higher per se performance for seed yield per plant and other component traits and hence considered as superior parents. The hybrids viz., BM4 x PDM1, JM 10 x AKM 8802, JM 721 x PDM1, ML131 x HUM 1 and TARM 2 x TJM 3 were observed as superior specific combiners for seed yield per plant and its component traits. These hybrids or cross combinations might be utilized for further improvement of seed yield in green gram.
