Combining, earliness, short anthesis to silking interval and yield based selection indices under intermittent water stress to select for drought tolerant maize. Joint regression is the most popular among univariate methods because of its simplicity of calculation and application (aremu, 2005 aremu, c o days to anthesis and silking, anthesis silking interval (asi), shelling percentage, grain yield and stover yield connect with taylor & francis. Lizaso et al (2017) incorporated new thermal time calculation, and the simulation of the anthesis-silking interval also based on previous work (lizaso et al, 2003c lizaso et al, 2007), the explicit and distinct impact of heat on pollen and silks was described together with the overall impact on grain yield (lizaso et al, 2017. Anthesis silking interval is the characteristic used in maize for selection of drought tolerant genotypes.
The positions of the 68 mqtl for grain yield and anthesis silking interval the 95% genetic confidence interval of mqtl for grain yield and anthesis silking interval are shaded in green and pink colors, respectively, while those shaded in black coincided for both traits. Grain yield, female flowering, male flowering, anthesis-silking interval epistasis demands vast amounts of calculation for its identification, but the consideration of epistatic effects in gs is an issue that needs to be addressed in the future in conclusion, gs may be regarded as a potent, attractive and valuable approach for plant. During maize (zea mays l) growth and change of anthesis-silking interval (asi) is one of the most serious consequences to realize the genetic basis of asi, a recombinant inbred line (ril) population.
Tuxpe~no germplasm and contrasting in anthesis silking interval (ribaut etal, 1996, 1997), and four inbred lines from a p1 9 p2 this allowed calculation and adjustment of soil water content to target values corresponding to the desired soil water potential. Shorter anthesis–silking interval, measured as the difference in day(s) between appearance of silk in the ear and pollen dehiscence in the tassel of a plant, is an important. Fuad-hassan a, tardieu f, turc o drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected to soil water deficit.
Bolaños and edmeades (1993) showed that the anthesis-silking interval (asi) accounted for a remarkable 76% of variation in grain yield across a range of cultivars and watering regimes, with yield reductions of almost 10% per day increase in asi. Ear leaves no, no per plant and anthesis-silking interval (asi) the highest and the lowest grain yield with 18/92 and 10/59 ton/ha was belonged to the hybrid of number 15 (l105k74/1) and 24 (s61l105. Anthesis-silking interval is a good indicator finally determine harvest index the growth and of movement of newly produced assimilated to the ear, emergence of silks is delayed when water stress occurs cob growth, number of grains and also the water potential calculation of anthesis-silking interval (asi):.
In replications where both gddta and gddts were evaluated, the anthesis–silking interval was also calculated as the difference in gdd between dta and dts (gddasi) ph and eh were measured in centimeters as the distance between the ground and the last leaf node or. Drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected to soil water deficit drought-induced changes in anthesis-silking interval are related to silk expansion: a spatio-temporal growth analysis in maize plants subjected to soil water deficit authors. And silking, anthesis silking interval (asi), shelling percentage, grain yield and stover yield the data collected were analyzed separately for each nitrogen level using analysis of variance (anova. When soil water deficit occurs before flowering, silk emergence out of the husks is delayed while anthesis is largely unaffected, resulting in an increased anthesis-silking interval (asi) (edmeades et. Grain yield was measured every season and anthesis-silking interval (asi) in most seasons during at least one season in each site, grain and stover samples collected at harvest were analyzed for biomass response to n and essential macro/micro-nutrients.
Preferred name: anthesis silking interval synonyms: asi (related) antskit (related) flwslkinter (related) definitions: a difference of the average number of days between the maize tassel flowering and the first visible silk (stigma) on the maize ear. Data was recorded on plant height, days to anthesis and silking, anthesis silking interval (asi), shelling percentage, grain yield and stover yield the data collected were analyzed separately for each nitrogen level using analysis of variance (anova. Ten plants from the second row of each plot were initially assessed before anthesis in the field, and six traits, including plant height, ear height, stem diameter, day-to-tassel, day-to-silk, and anthesis-silking interval, were evaluated.
Seedling emergence, anthesis-silking interval, days to anthesis and silking had high heritability but the genetic coefficient of variations was low this indicates that though, the character is highly heritable, its improvement through early generation selection may not give the desired results. Impact of high temperatures in maize: phenology and yield components (location x sowing) a duncan test at 005 significance level was applied to compare means and for the calculation of standard deviations per treatment in spite of these variations in crop cycle, the anthesis-silking interval (asi) was similar in the three locations. 50% silicon, days to 50% anthesis, anthesis-silking interval and days to 50% maturity variance components were estimated based on expected prior to the calculation of the squared euclidean distance, the data were standardizedto determine the desired number of clusters, the. Partial restoration of male fertility was inherited like an oligogenic trait therefore, a marker-assisted counter-selection of major qtl in bins 209, 306 and 703 is promising, but the importance of these loci must be verified with other germplasm and under different environmental conditions.
Waxy corn lines for new hybrid variety development in vietnam materials and methods plant material anthesis-silking-interval (asi) trait shorter, because asi involving evaluation selection of purple waxy corn lines for new hybrid variety development. Breeding for drought tolerant maize in kenya: selection for anthesis-silking interval the role and regulation of the anthesis-silking interval in maize in: westgate, me boote, kj (eds. Most prominently, the relationship between anthesis-silking interval and grain yield became much weaker in these hybrids conversely, significant negative correlations were found between tassel dry weight and grain yield.
