TL;DR: Catalyzed phenol-hypochlorite and ninhydrin colorimetric procedures were adapted to the Technicon AutoAnalyzer for simultaneous determination of ammonia and total amino acids in ruminal fluid or ruminal in vitro media and indicated high degrees of accuracy and precision for both ammonia and amino acid analyses.

TL;DR: Procedures are given, using sib pairs, for estimating linkage between a knownm-allele locus and a hypothesized two-alleel locus that governs a quantitative trait.
Abstract: Procedures are given, using sib pairs, for estimating linkage between a knownm-allele locus and a hypothesized two-allele locus that governs a quantitative trait. Random mating and linkage equilibrium are assumed. Also given are parametric and nonparametric methods for detecting linkage when the trait in question is governed by several two-allele loci, provided there is no epistasis.

TL;DR: A unified presentation, a synthesis, and an evaluation of the methods employed in the estimation of heritability in plants are presented, discussing the use of both collateral and lineal relatives and the biases present in the estimators.
Abstract: A unified presentation, a synthesis, and an evaluation of the methods employed in the estimation of heritability in plants are presented. Asexual, cross‐fertilizing, and self‐fertilizing diploid species, as well as annual and perennial ones, are considered. All broad‐ and narrow‐sense heritabilities are defined on individual and family bases for prediction of response to selection for a target population of environments in space and time. Narrow‐sense heritabilities are defined in cross‐fertilizing species for expected response to variations of mass, half‐sib, and full‐sib family selection for the next generation and the long term, and similarly in self‐fertilizing species. The use of both collateral and lineal relatives to estimate heritability is discussed, and the biases present in the estimators are given. Many departures and variations of the common procedures are discussed. The standard errors of heritability estimators and confidence intervals are presented.
