A triple-cross method is described as an alternative to the double-cross method for the production in kale of 100 per cent hybrid seed. This new method would reduce the labour involved and improve yields in the early stages of seed multiplication. These advantages would justify slightly lower yields of forage from triple-cross hybrids than from double-crosses. 

Population improvement and synthetic cultivar production in forage kale (Brassica oleracea L.)

TLDR
It is demonstrated that forage kale population improvement involving full-sib and selfed families can be done on an annual cycle, followed by production of a synthetic cultivar, and this new breeding method compares favourably with the two successful methods used to date.

Methods of producing F1 hybrid swedes (Brassica napus ssp. rapifera)

TLDR
The methods by which F1 hybrid swedes can be produced are discussed and the integration of self-compatible lines into these methos should simplify their use.

Carbon dioxide treatment as an effective aid to the production of selfed seed in kale and Brussels sprouts

TLDR
The use of carbon dioxide to overcome the self-incompatibility mechanisms in marrow-stem kale and Brussels sprouts is discussed and a method is described of applying it as a routine procedure for the production of selfed seed in quantily.

Studies on a diallel cross and double-cross hybrids among various Brassica oleracea types

TLDR
Three unrelated pairs of inbred lines from marrow-stem kale, thousand headed kale, and Scotch curled kale, together with 3 lines from Chou Fourrager Jaune, Brussels sprouts, and January King cabbage were used to produce a diallel cross to study general combining ability and specific combining ability.

Productivity of F hybrids of botanical varieties ofBrassica oleracea L.

TLDR
A scheme for the production of F1 hybrid seed is suggested, based upon an adaptation ofThompson's (1964) ‘Triple-cross’ technique.

The production of F1 hybrid swedes (Brassica napus ssp. Rapifera) by the utilisation of self-incompatability

TLDR
Six inbred lines from a swede with naturally occurring self-incompatibility were each isolated with aSwede cultivar containing marker genes, showing increases in dry matter yield and intervarietal hybrids over the higher parent.

POSSIBLE APPLICATIONS OF SELF-INCOMPATIBILITY IN THE PRODUCTION OF BRASSICA NAPUS CULTIV ARS

Brassica napus is usually self-compatible, but several S-genes controlling the dominance of pollen and style reactions are now available. The ways in which selfincompatibility could be used to

Kale population improvement and cultivar production

TLDR
It was demonstrated that faster progress could be made by switching from half-sib to full-sIB family selection, as expected from theory, and Multiplication of the half- sib family with the highest digestibility achieved an improvement in this trait, without a reduction in digestible organic matter yield, and was marketed as cultivar Grampian.

Use of Botanical Varieties of Brassica oleracea L. in the Breeding of Forage Kale

At present, forage kale cultivars for feeding cattle and sheep are either open-pollinated ones from population-improvement schemes within suitable botanical varieties of Brassica oleracea or

Linkage between S alleles and pigmentation genes in marrow-stem kale, brassica oleracea

TLDR
Close linkage has been found in marrow-stem kale between S alleles and the genes controlling hypocotyl and stem colour, spotting of anthers and marking of sepals and fruit.

TLDR
After the severe winter 1953–1954, it was observed that a heterosis effect for cold resistance also exists and these results are discussed and interpreted according to Jones' dominance hypothesis.
