“…In the present study, high heritability (>75 per cent) coupled with a high genetic advance over mean (GAM) was noticed for all the characters except days to 50% flowering (74.60) and days to maturity (58.40)indicating that the selection made for the improvement of these characters would be effective as they are more likely to be controlled by additive gene actions. High heritability estimates observed in the present investigation are in accordance with the findings of Yaqoob et al (2015), Yohannes et al (2015) and Shamini (2018) for seed yield per plant in sorghum. High estimates of broad sense heritability and low genetic advance is due to the presence of non-additive genetic effects and high genotype and environment(G×E) interactions.…”

An experiment was conducted to know the variability among 22 maintainers on maldandi and milo source of male sterility in rabi sorghum along with four checks M 35-1, BJV-44, DJ6514 and PKV Kranti. The study revealed considerable amount of variability for all the characters studied. The genotypic and phenotypic coefficients of variation observed to be the highest for grain yield per-plant, the number of seeds per panicle and panicle weight. All the characters showed an arrow difference between PCV and GCV, indicating that the observed variability has been primarily due to genotypic differences with the least influence of environment. High heritability coupled with high genetic advance over mean was noticed for all the characters studied there by indicating that the selection would be effective in improvement of these characters as they are controlled by the additive genes. Based on mean performance the genotypes IS 14010 and IS 19445 were found significantly superior over the checks M35-1 and DJ6514.

“…The variation available for leaf length and width was comparatively less to enable effective selection process for these traits. The trait stem diameter showed high PCV and moderate GCV (Shamini and Selvi, 2018). The PCV is greater than GCV in the character stem diameter this indicates the influence of the environmental on the trait was more.…”

Sorghum (Sorghum bicolor [L.]Moench) is a versatile crop grown in more than 100 countries in tropics and semiarid regions for food, fodder, fuel and fiber. Red sorghum is noted for its rich phenolic content and specifically 3-deoxyanthocyanin content that lacks hydroxyl group at C-3 position. A total of 80 sorghum landraces collected from various sources from Tamil Nadu were evaluated during Kharif, 2019 to record morphological diversity present in the accessions. The 12 quantitative traits were recorded stage wise following IIMR DUS descriptor. The quantitative data collected from 80 sorghum landraces were statistically analyzed by variability study and association study. The high PCV and GCV were recorded for height upto flag leaf, flower length, panicle emergence, total height, panicle length, panicle branch length, panicle neck length, thousand grain weight and single plant yield. The moderate level of GCV and PCV was recorded for leaf length and leaf width. The trait stem diameter showed high PCV and moderate GCV. The variability study indicated that more variations were found in the population which facilitates efficient selection. The grain yield was positively related with leaf width and thousand grain weight. The yield was negatively influenced by height upto flag leaf, flower length, total height, panicle length, panicle neck length and panicle emergence. The results of correlation analysis revealed that the selection for high yielding landraces can be carried out phenotypically by selecting landraces with high grain weight, early panicle emergence, lesser height upto flag leaf, reduced neck length, reduced flower length and more leaf width to develop a desired high yielding sorghum variety.
