SummaryIn a population of Allium stracheyiBaker (2n=14) growing in Darjeeling both diploids and polyploids occur. The diploids contain B-chromosomes varying from 2–10 in number. Polyploids are conspicuous by absence of B-chromosomes. These in diploids are found in the pollen mother cells and also in the pollen, and some are provided with subterminal constriction.Diploid individuals when brought from Darjeeling to Calcutta (i. e. from temperate to tropical regions) became polyploid within a… 
Genetic systems in Allium
TLDR
Allium species show very little variation in the symmetry of their chromosomes within as well as between their complements, and in some species they also carry heterozygosity.
The nature and behaviour of supernumerary chromosomes in the rhizirideum group of the genus Allium
TLDR
Individuals at various levels of ploidy in three species of Allium contain a morphologically uniform B-chromosome, a supernumerary different in character from other B-types recorded for the genus.
Reporting of B-Chromosomes in Trachyspermum ammi (L.) Sprague (Ajwain)
TLDR
No change has been observed in the number of B chromosomes despite the duplication of A chromosomes in autotetraploid plant and the meiotic behaviour of B-chromosomes was analyzed in Trachyspermum ammi (L.) Sprague.
Cytogenetics of tropical bulbous ornamentals III. Mitotic mosaicism in 3x Crinum augustum
SummaryTriploid Crinum augustum contains two types of complements (2 n = 33, 32 + Te) in the meristems of primary and secondary roots, together with a small amount of aneusomaty. This condition is
Polyploidy and b chromosomes in Alium flavum from Serbia
TLDR
One submetacentric B chromosome representing 1% of the genome, smaller than the smallest chromosomes of the standard set, was present in some plants, which is the first finding of Bs in tetraploid A. flavum.
Influence on chromosome behaviour, nucleic acid content and ultra-structural analysis of accessories inUrginea indica KUNTH.
The occurrence of polysomaty was noted in a diploid cytotype ofUrginea indica with B chromosomes. These accessories could be clearly distinguished from the other chromosomes in their stainability,
EFFECTS OF TEMPERATURE AND SOIL MOISTURE ON FREQUENCY OF ACCESSORY CHROMOSOMES IN RYE, SECALE CEREALE L.
In order to find the correlation between the environmental factors and frequency of accessory chromosomes in different populations of rye, clonal plants divided from a plant to get the uniformly
Cytological Observations on some W . Himalayan Monocots lll
The family Alliaceae is represented by a single genus Allium in the W. Himalayas. A perusal of the literature reveals that this genus has been fairly well investigated since it yields ideal material

Morbid mitosis and the activity of inert chromosomes in sorghum
TLDR
Sorghum purpureo-sericeum has five paris of active, A, chromosomes and a variable number of extra, B, chromosomes in equilibrium in the wild population and such changes could evidently establish malignant propensities in somatic cells by stimulating recurrent mitosis.
Accessory chromosomes in Poa alpina
TLDR
In a strain of Poa alpina the chromosome conditions were found to be remarkable, a higher number of chromosomes being present at meiosis in the p.m.c. than in the root tips (Muntzing, i 946a); preliminary observations have now been extended.
Chromosome Diminution in a Plant
TLDR
A new species of Sorghum, S. purpureo-sericeum, from the Sudan, is described, in which I have described plants with varying numbers of extra chromosomes.

TLDR
This reaction suggests a mechanism for the formation of 5-phenylhydrazinouracil from the action of phenylHydrazine on 5,5-dibromo-6-hydroxy-5,6-dihydrouracils which was observed by Levene.

TLDR
It is thus not the chromosome theory but the Mendelian situation which is crucial for classical genetics, because the chromosomes did not make the law: they obeyed it.
