<p>Anther culture technique offers great opportunities to accelerate breeding progress. The current study aimed to develop some good doubled haploid lines (DH) through anther culture technique and to evaluate them along with their five parents including two check varieties for yield and yield related traits. Analysis of variance revealed that varietal differences were signified and wide variability present among the genotypes with respect to all the characteristics studied. Correlation analysis revealed that grain yield was highly positive correlated with panicle length. The information on the inter association among the yield attributing characters showed the nature and extent of relationship with each other. Consequently, this will help in the improvement of different characters along with yield in breeding programmes.</p>

<p>Genetic devlopment to imrove genotypes with high quality is the most important approach of rice. Thus, anther culture technique is one of straight forward approaches for improvement of rice cultivars with good grain quality. Therefore, this investigation aimed to develop some doubled haploid lines (DH) through anther culture technique and evaluate them along with their five parents including two check varieties for some nutritional characteristics. The results indicated that the three mineral element contents (Zn, Mn and Fe) of rice grain were clearly different among genotypes (DH), which implied that genotypic variations might provide opportunities to select for higher mineral element content. Analysis of variance revealed that the differences among genotypes were significant for all studied traits. Highly significant positive correlations were recognized among the studied characteristics. Accordingly, Rice lines with the high nutritional values will use as donors for this trait in rice breeding programs for exploitation and in hybridization. <strong></strong></p>

<p>ABSTRACT<br /><br />Doubled haploid rice formation through anther culture becomes one of the alternatives in the plant breeding. The lines need to be characterized, clustered, and selected. This study aimed at determining heritability, characters, and cluster of doubled haploid lines obtained from anther culture. This experiment was conducted at IPB Rice Field Experiment Station, Darmaga, Bogor from October 2016 until January 2017. The experiment was managed according to randomized complete block design (RCBD) with 3 replications and genotype as the single factor treatment. Genotypes used were 60 genotypes consisting of 56 doubled haploid lines and 4 control varieties. The controls were Ciherang, Inpara 5, Inpari 29, and Inpari 34 Salin Agritan. The results showed that all characters have significant effect and high heritability (above 60%), so they could be used as a selection character. The tested genotypes could be grouped into three main groups. The first group consisted of 11 genotypes, the second group consisted of 44 genotypes, and the third group consisted of 5 genotypes. The main group determinant characters were productive tillers, percentage of filled grain number, plant height, panicle length, and weight of 1,000 grains. The number of filled grain and productive tillers can be used as selection characters together with yield potential.<br /><br />Keywords: filled grain, heatmap, panicle length, productive tillers, yield potential<br /><br /></p>

Diallel crossing is a method that is widely used to determine the ability to combine each individual so that it can identify the potential elders to be used in crossbreeding programs to assemble high yielding varieties. This experiment aims to determine the combining power of dialelic crosses of several varieties of rice using the Griffing II method, carried out in the experimental field of the Faculty of Agriculture, Mataram University in Nyiur Lembang Village, Narmada District, West Lombok Regency, from February to July 2019. This experiment uses the method experiments carried out in the field. The materials used in this experiment were four parents, namely IPB 3S variety, Situ Patenggang variety, Inpari 32 and G11 strain and the phenotype of the cross between the four parents. The experimental results showed that the effects of general affinity and special affinity for all observed characters (plant height, number of productive tillers, number of non-productive tillers, panicle length, number of filled grain, number of empty grain and weight of 100 grains) were significantly different, except on the effect of general affinity for the number of non-productive tillers showed no significant difference. The results of the combined power analysis of the four elders were positive, so it can be said that the four elders would get good results when crossed with a number of other genotypes.

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
