Combining ability analysis for harvest index in winter wheat

Euphytica, 1991
Cereal breeders have used harvest index (HI) as a selection criterion in segregating generations to identify physiologically superior lines with improved partitioning of total assimilate into grain. Information on combining ability for HI of the hard red winter wheat (Triticum aestivum L.) cultivars of the Southern Great Plains is not available.

PROLONGED FREEZING OF DARK-HARDENED SEEDLINGS FOR RATING AND SELECTION OF WINTER WHEATS FOR WINTER SURVIVAL ABILITY

Canadian Journal of Plant Science, 1988
Winter survival ability is an important trait in cultivars of winter wheats (Triticum aestivum L. em. Thell.) bred for cold climates; however, it is laborious to measure accurately under field conditions. This report evaluates a simple artificial freezing procedure as a screening test for winter survival ability.

COMBINING ABILITY IN WINTER SORGHUM

Madras Agricultural Journal, 1996
The nature of gene action through combining ability analysis for grain yield and its components was studied in 5 X 5 diallel cross of sorghum. Estimates of gea and sca indicated the influence of both additive and non additive gene action for the inheritance of grain yield, stem girth and plant height.

Genomic selection for winter survival ability among a diverse collection of facultative and winter wheat genotypes

Molecular Breeding, 2019
Winter survival ability is important for autumn sown winter wheat (Triticum aestivum L.) in regions with cold winters. Wheat vernalization and photoperiod genes influence adaptation by regulating the timing of the transition from vegetative to reproductive growth to protect the floral meristem from cold temperatures.

COMBINING ABILITY FOR MALE FERTILITY AND YIELD IN HYBRID WINTER WHEAT

Canadian Journal of Plant Science, 1979
Sixty-seven F1 winter wheat hybrids (Triticum aestivum) between eight cytoplasmic male sterile (cms) lines with T. timopheevi cytoplasm and 10 fertility restoration (Rf) lines carrying restoration genes from T. timopheevi, T. spelta and T. aestivum ’Primepi’ were analyzed for male sterility and grain yield in a field trial.

STUDY OF WINTER RYE SAMPLES BY GENERAL COMBINATIONAL ABILITY

PROBLEMS OF SOIL FERTILITY IN MODERN AGRICULTURE
The purpose of the study is to isolate samples of winter rye with high overall combining ability to create a new synthetic population. The research was carried out in 2018 – 2021 on the experimental fields of the Krasnoyarsk Research Institute of Agriculture.

Relevance of Specific versus General Combining Ability in Winter Wheat

Crop Science, 2012
ABSTRACTKnowledge of quantitative genetic parameters is crucial in allocating resources for different steps of multistage selection programs. The main objective of the present study was to investigate the magnitude of variance of general combining ability (GCA) and specific combining ability (SCA) effects and their interaction with environments in ...

Assessment of combinational ability of inbred lines of winter rye by the topcross method

Rossiiskaia selskokhoziaistvennaia nauka, 2023
Dentification perspective on combinational ability of the inbred lines of winter rye is an important stage in hybrid breeding. The purpose of researches - to estimate the general and specific combinational ability of the inbred lines of winter rye by a method of full top crossings. As a maternal form 30 homozygous lines of rye bearing sterile cytoplasm

Assessment of the combinational ability of inbred winter rye lines in plant height

Rossiiskaia selskokhoziaistvennaia nauka
The aim of the research is to evaluate the general and specific combinational ability of inbred winter rye lines in plant height and identify relatively short-stemmed combinations. The starting material for the crossing was 22 homozygous rye lines carrying sterile cytoplasm of the Pampa type. The male fertile homozygous lines mf H-1423, mf H-1247, m fH-

Response to selection, combining ability and heritability of coleoptile length in winter wheat

Euphytica, 2008
Selection of winter wheat cultivars with long coleoptiles is an important component of improving emergence, weed suppression and grain yield in low rainfall regions of the world. Seven winter wheat cultivars were hybridized in a Griffing’s half-diallel mating design, method 2 (reciprocals excluded, parents included), model 1 (fixed), and the progeny ...
