Rheological test of flour and baking test with sugar-snap cookies were also performed. The Hardness Index of the NILs ranged between 13.86 and 47.13. The flour of the NILs had relatively lower proportion of particles >150 μm than in the classes of 0 to ≤ 55 μm and > 55 to ≤ 105 μm. Starch damage of all the NILs was significantly lower than the hard grain parent DBW14 (4.54%) and the popular variety HD2967 (7.49%). All the 16 NILs showed optimum Solvent Retention Capacity of NaSRC ≤ 64% and SucroseSRC ≤ 89%. The farinograms of all the NILs were typical of weak gluten with low water absorption capacity. The alveographs showed an Extensibility ratio (P/L) between 0.17 and 0.36, and much lower Deformation Energy (46-94 J) for the NILs. The spread factor of the cookies made with the flour of the NILs varied between 7.90 and 12.77, while that ofthe soft grain parent was 9.44. The findings suggest that the NILs developed in the Indian wheat variety DBW14 may be suitable for production of flour for making cakes, cookies, muffins, etc. These NILs, after evaluation in varietal trials and release for cultivation, can have a strong domestic and export potential. Thus, marker assisted selection is a useful tool for the targeted quality breeding.","PeriodicalId":13321,"journal":{"name":"Indian Journal of Genetics and Plant Breeding","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45805923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PCA reduces dimensional complexity into nine principle axes with PC1 account maximum variable genotypes, namely, JR-1009, ANP-553, JR-1062-1, JR-1103-1, JR-1023-1, JR-1054-4, IR09N 261, JR-1008, NPT-3806, and JR-81.

Can the non-grain yield parameters of yield like height, flowering and maturity be explored as an alternate for further yield enhancement? This study comprehends such possibilities by analysing performance of the released and pre-released varieties evaluated in ten diverse production environments of India during the period 2000-2021. Regression analysis has highlighted relevance of these three crop expressions in wheat yield and based upon their contribution, selection criteria has been suggested for different production environments of India. Magnitude of impact varied under each environment and their collective contribution was highest in a production environment where growth condition was most favourable for wheat growth i.e., north-western plains. Increase in height and maturity duration coupled with early heading was found useful in this region for both wheat category, i.e., timely-sown and late-sown. These three yield determinants were found highly effective in timely-sown of the adjoining north-eastern plains also but under late-sown condition, prolonged heading was the chief yield predictor. Height for timely-sown and maturity for late-sown condition was most crucial for central India. Delayed heading in timely-sown and late flowering with extra height in late-sown wheat had been tipped for yield improvement in peninsular India. Delayed maturity for timely-sown and height for late-sown wheat had been suggested for productivity enhancement in the northern hills. Besides grain yield, this selection strategy based upon height and crop phenology also enhanced grain weight in certain environments. At a time when selection for grain attributes is not providing further push in productivity enhancement; it would be worth trying to explore these non-grain field indicators as selection strategy for further advancement in productivity of bread wheat.","PeriodicalId":13321,"journal":{"name":"Indian Journal of Genetics and Plant Breeding","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42676083","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Map-based cloning of rice grain size-related genes impacts the genetic regulation mechanism of rice yield formation. Here we identified bgl mutant in rice which exhibits increase in grain length and panicle length with the decrease in number of grains per panicle and no observable difference in grain thickness and number of tillers as compared to the wild type (WT). Scanning electron microscopy observation of bgl mutant spikelets hull indicates an upsurge in number of external epidermal cells in a longitudinal way than the WT. Hence, it is likely that the long-grain phenotype was due to increased cell number longitudinally. Starch granule in both bgl and WT were large, sporadically polyhedral and densely packed, indicating no differences, signifying that both bgl mutant and WT have less chalkiness content. Genetic analysis showed that the bgl mutant was controlled by a recessive single gene, and was finely located on chromosome 3 through map-based cloning, within a physical distance of 40kb. Sequencing analysis revealed A to T substitution in the seventeen exons of LOC_Os03g44500 resulted in an amino acid change from Tryptophan (Try) to Phenylalanine (Phe). Taken together bgl mutant has a pleiotropic effect on grain yield and grain quality.","PeriodicalId":13321,"journal":{"name":"Indian Journal of Genetics and Plant Breeding","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47671881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mean number of effective alleles, Shannon information index and gene diversity i.e., 1.38 ± 0.013, 0.35 ± 0.010 and 0.23 ± 0.007, respectively were obtained with RAPD + ISSR markers. The analysis of molecular variance generated by RAPD + ISSR revealed a higher genetic variation (87%) within population as compared to that of among population (13%). Nei genetic distance was maximum (0.185) between Jammu and Kashmir and Punjab populations. Significant Mantel correlation (r=0.551,) was obtained between RAPD and ISSR markers. Bayesian clustering pattern obtained through STRUCTURE software showed four gene pools. Based on the genetic information obtained with regards to Indian willow by combining the RAPD and ISSR marker systems, it is proposed that an individual tree be selected within populations rather than among populations for the improvement of economic traits of Indian willow alongwith conservation of entire ecological populations.","PeriodicalId":13321,"journal":{"name":"Indian Journal of Genetics and Plant Breeding","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44188700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
