Narrow sense heritability
-
Despite the success of genome-wide association studies (GWAS), there still remains “missing heritability” for many traits. One contributing factor may be the result of examining one marker at a time as opposed to a group of markers that are biologically meaningful in aggregate.

Most traits targeted in the genetic improvement of hop are quantitative in nature. Improvement based on selection of these traits requires a comprehensive understanding of their inheritance. This study estimated quantitative genetic parameters for 20 traits related to three key objectives for the genetic improvement of hop: cone chemistry, cone yield and agronomic characteristics.

The high narrow sense heritability of carcass traits suggests that the underlying additive genetic potential of an individual should be strongly correlated with both animal carcass quality and quantity, and therefore, by extension, carcass value.

In the present investigation, 21 F1s were generated by crossing seven lines and three testers following Line x Tester mating design. Nine yield traits of barley were studied on 21 crosses to estimate heritability in narrow sense, genetic advance in per cent of mean, phenotypic and genotypic coefficient of variation.

A study of twenty one F1 hybrids of Muskmelon (Cucumis melo L.) in a half-diallel set involving seven parents showed over-dominance and low narrow-sense heritability for all the characters except node no of first female flower, average fruit weight, first fruit harvest and yield per plant. In all these characters, the dominance component of genetic variance (H1) was higher than the additive component of genetic variance (D) indicating predominance of dominant gene action over additive gene action and commercial exploitation of heterosis for improvement of these traits.

In order compute genetic variability, heritability and genetic advance expressed as per cent of mean, an investigation was carried out with 79 plants of F2 population of MFC-09-12 × PGCP-12 and 90 plants of F2population of MFC-08-14 × PL-3 in cowpea. Considerably high amount of variability was observed for the thirteen quantitative and qualitative characters under study.

The genetic analysis was carried in a 6x6 half diallel breeding programme of common bean for thirteen yield and yield attributing parameters. Both additive and non-additive genetic components were responsible in the genetic system controlling yield and its component characters. The additive (D) genetic variance was significant for Days to first flowering, Days to fifty per cent flowering, Days to maturity and pod length.

This study was conducted to have basic information about the genetic nature of variation present in the clonal population of sugarcane. For this mean, range, genotypic coefficient of variation, phenotypic coefficient of variation, broad sense heritability and genetic advance was calculated using 144 sugarcane clones along with five standards in augmented block design. All the clones were differed significantly for all the 13 traits indicating that sufficient amount of variability was present in the experimental material.

The objectives of this study were to estimate the narrow sense heritability of the examined characters and to find their linked simple sequence repeats (SSRs) using bulked segregant analysis (BSA) in rice (Oryza sativa L).
