A Tertiary Trisomic in Barley (Hordeum vulgare L.)
(1977) Ganesh Prasad
Tertiary trisomics which occur in the selfed progeny of interchange heterozygotes, have gained considerable importance in genetics and breeding of barley. Ramage and Tuleen (1964) proposed the use of ‘Balanced Tertiary Trisomics’ (BTT) for maintaining lines of lethal and sterile genes. The concept of ‘Hybrid Barley’ production through the use of BTT was given by Ramage (1963, 1965) and a hybrid barley variety was released in U.S.A. (Ramage and Wiebe 1969). The present paper reports a tertiary trisomic which was isolated from the progeny of a gamma-ray induced translocation T 2-6 in barley. © 1977, Japan Mendel Society, International Society of Cytology.

Effects of Some Growth Substances on Mitosis
(1977) Ganesh Prasad; K. Das
Cytological effects of three growth substances namely, Gibberellic acid (GA), Indole-butyric acid (IBA), and 2, 4-Dichlorophenoxyacetic acid (2, 4-D) were studied on root tip mitosis of Vicia faba treated with 10 and 50ppm concentrations and 3, 6 and 12 hours durations. GA enhanced cell division while 2, 4-D and IBA inhibit ed it and were more toxic than GA. Main effects at chromosomal level were chro mosome breakage, bridge formation, C-mitosis, micronuclei formation, stickiness and chromosome condensation. © 1977, Japan Mendel Society, International Society of Cytology.

Identification of Chromosomes Involved In Certain Barley Translocations
(1977) Ganesh Prasad
Chromosomes involved in three translocation lines in a 6-rowed barley variety K 12 were identified by studying the meiosis in the hybrids between the translocation lines and Burnham's translocation testers. The chromosomes identified were 1-4 (line 3047), 1-3 (line 3103) and 4-7 (line 3104). © 1977, Japan Mendel Society, International Society of Cytology. All rights reserved.
