Mutagenic response of rhodes grass (Chloris gayana Kunth.) to gamma rays. II. Studies on second (M2) generation parameters

Abstract: The effect of gamma rays on parameters such as chlorophyll mutation frequency and spectrum, mutagenic effectiveness and efficiency and viable mutation frequency and spectrum were studied in M 2 generation of Rhodes grass employing nine doses of gamma rays . The chlorophyll mutation frequency increased in a linear fashion at low and medium doses and was erratic at higher doses . The chlorophyll mutant spectrum included albina, xantha, chlorina, viridis, tigrina, striata, albo-xantha and albo-viridis . The frequ… Show more

“…1) and broad-leaved (Fig . 2) in highly sterile and partially sterile types respectively, were isolated from M2 viable mutations (KRISHNA et al ., 1984b) . A brief description of the mutants is given below : Non-arrowing type : relatively broad-leaved, short stem length, absence of inflores- cence, heavy tillering and bushy growth habit (in 50 krad) Broad-leaved type : strikingly vigorous, broad-leaved, tall with heavy tillering associated with partial sterility (in 40 Krad) .…”

“…Seeds harvested from the main tiller of M t plants were raised in nursery, screened for chlorophyll mutants and then transplanted in the main field to score viable mutations (KRISHNA et al ., 1984b) . The selected viable mutants in the M 2 generation viz ., non-arrowing and broad-leaved mutants of practical importance were multiplied through rootslips and studied for their forage yield and nutritive quality by proximate analysis .…”
