Brit.

/ˌmɒnə(ʊ)ˈhaplɔɪd/, U.S.

/ˌmɑnəˈhæpˌlɔɪd/

Origin: Formed within English, by compounding. Etymons: mono- comb. form, haploid adj.

Etymology: < mono- comb. form + haploid adj. Compare polyhaploid n. at poly- comb. form 1.

Botany.

A. n.

A monoploid plant derived spontaneously or by a variety of artificial techniques from a normally diploid species.

1935 Y. Katayama in Japanese Jrnl. Bot. 7 374 The writer has classified (though provisionally) the haploid plants as follows: the haploid from diploid species (or basal species) is called a monohaploid.

1981 Philos. Trans. (Royal Soc.) B. 292 499 One cycle of haploidization leads to dihaploids; a second cycle produces monohaploids.

1995 Caryologia 48 275 (title) Evaluation of meiosis in cucumber (Cucumis sativus L.) monohaploids.

B. adj.

Designating or consisting of such plants.

ΚΠ

1975 Euphytica 24 567 Using endosperm markers it could be demonstrated that the endosperm in maize seeds with a monohaploid embryo is triploid.

1980 Science 4 Apr. 18/2 Thus, under the general heading of ‘potato’, there has been described an extensive array of Solanum species, or within S. tuberosum ssp. tuberosum, a range of dihaploid and monohaploid lines.

1993 Theoret. & Appl. Genetics 87 328 Allotriploid somatic hybrids were obtained from fusions between protoplasts of diploid tomato and monohaploid potato.
