New reports of chromosome numbers inActinidia(Actinidiaceae)

Abstract

Chromosome numbers are reported for the first time for seven taxa ofActinidia: A. arguta var. purpurea, 2n = 8x = c. 232; A. deliciosa var. chlorocarpa, 2n = 6x = 174; A. deliciosa var. coloris, 2n = 6x = 174; A. glaucophylla, 2n = 2x = 58; A. guilinensis, 2n = 2x = 58; A. indochinensis, 2n = 2x = 58 and A. setosa 2n = 2x = 58. Ploidy variation has also been observed in A. melanandra and confinned in A. chinensis var. chinensis: 2n = 2x = 58 and 2n = 4x = 116. Chromosome numbers for another 11 Actinidia taxa were found to be in agreement with those previously reported. Chromosome numbers were the same for male and female plants of the same taxon. Detailed studies of chromosome morphology was not possible under the light micro- B96060Received 30 September 1996; accepted 10 March 1997 scope because of the small size of Actinidia chromosomes.

“…giraldii and shown to be diploid is now thought instead to be A. hypoleuca, a species sometimes treated as a variety of A. arguta (e.g., Phivnil et al 2005).

“…The conclusion that A. deliciosa var. chlorocarpa contains tetraploid and hexaploid races may be incorrect if the plant studied by Yan et al (1997c) is not true to type. Once again, A. chinensis is the only taxon in which intrataxon ploidy races have been studied at all adequately.…”

Current status and prospects of kiwifruit (Actinidia chinensis) genomics

“…키위의 기본 염색체 수는 x=29이며, 종 또는 품종에 따라 2배체에서 8배체에 이르기까지 다양한 배수 성을 갖는다 (Huang 2014;Watanabe et al 1990;Yan et al 1997). 우리나라에는 다래(A. arguta Planch.…”

“…), 섬다래(A. rufa Planch.) 등 4종이 분포하고 있다 (Cui et al 2002;Huang 2014;Watanabe et al 1990;Yan et al 1997). 키위는 전년도에 생장한 액아로부터 새로운 줄기가 나 오며 1년에 6 m까지 자란다.…”

Characterization of a RAPD fragment unique to species with hairy fruit skin in the genusActinidia

“…The genus Actinidia, or kiwifruit, includes more than 60 species of dioecious vines that originated in China and neighboring countries (Ferguson, 1990;Yan et al, 1997). Its fruit has been acclaimed for its nutritive and medicinal value as a very rich source of ascorbic acid.…”
