In recent years, the demand of chilli has tremendously increased due to its attractive market price and multifarious used in cooked and processed forms. At present people are much concerned about the fruit quality and yield. Therefore, attention is being paid for development of genotypes having high yield potential with desirable fruit quality characters in a short period of time. For this purpose, seeds of chilli were mutagenised with ethyl methane sulphonate (EMS) and diethyl sulphate (DES) to determine their mutagenic sensitivity in M1 generation. The increasing concentration of EMS and DES decreased in morphological and yield characters. The spectrum of mutation and induced variability for various quantitative traits were observed in M1 generation such as germination (%), plant height, primary and secondary branches per plant, days to first flowering, fruit length (cm), fruit girth (cm), total number of fruits per plant, number of seeds per fruit, seed weight per fruit (g), 100 seed weight (g) and pericarp: seed ratio showed variability in chilli with the effect of EMS and DES. The percentage of chromosomal abnormalities in different mitotic stages was significantly higher than that of the control in all the treatment concentrations.

Induced variability was studied in the quantitative characters of mung bean (Phaseolus aureus Roxb.) after treatment with gamma rays, ethyl methane sulphonate (EMS), and hydrazine hydrate (HZ) in M1, M2, and M3 generations. The characters evaluated were seeds per pod, 100-seed weight, and total plant yield. The variability increased in almost all of the characters in the M1 generation. The mean number of seeds per pod and 100-seed weight decreased, whereas the plant yield did not show any particular trend. There was an increase in the mean values after gamma irradiation and EMS treatments in the M2 generation. However, HZ fails to show the same response. However, the mean values increased in the M3 generation. Estimates of heritability were higher for 100-seed weight, followed by plant yield, and then seeds per pod in the M3 generation. Coefficient of genotypic variation and genetic advance were high for the plant yield in M2 and M3 generations. In general, the genotypic coefficient of variation values, heritability, and genetic advance increased more in M3 as compared with M2, indicating that the significant gain could possibly be achieved through selection in M3 generation.Key words: quantitative, heritability, mutagenesis.

AbstractA parent strain of Aspergillus niger LW-1 producing β-mannanase, preserved in our laboratory, was isolated. A strain, N-9, was screened out and further treated with vacuum microwave irradiation and ethyl methane sulphonate (EMS). A mutant strain, E-30, producing a high and stable yield of β-mannanase was obtained through screening by solid-state cultivation on the basic fermentation medium and several generations of bevel subculture. Its enzyme activity (36 675 U/g) was increased by 2.15 times compared to that of A. niger LW-1 (17 048 U/g). The production of high-yield β-mannanase by E-30 remained stable when maintained at 4°C for 2 months.

Ecological Region

North east hilly eco-region of India is characterized by highly undulating topography and fragile ecology. Here the cultivation of rice on upland and medium land is not a profitable venture to farmers. Therefore, to find out alternative crop with high yield potential cultivars a three year field study from 2008 to 2010 on agronomic evaluation of groundnut cultivars under sub-tropical climate of North East hilly Agro-ecological region was carried out. The experiment consists of fourteen groundnut cultivars (V<sub>1</sub>- ICGS-76, V<sub>2</sub>- GG-2, V<sub>3</sub>- GG-13,V<sub>4</sub>-TG 37 A, V<sub>5</sub>-FeESG-10, V<sub>6</sub>-FeESG-8,V<sub>7</sub>-K-134,V<sub>8</sub>-GG-6,V<sub>9</sub>-SB XI, V<sub>10</sub> GG-11,V<sub>11</sub>-KAUSHAL,V<sub>12</sub>-GG-4,V<sub>13</sub>-GG-2,V<sub>14</sub>-GG-8) as treatment in randomized block design and replicated thrice. Results revealed that highest plant dry weight was produced by cultivar “KAUSHAL” (32.99 g/plant), while lowest was recorded with cultivar “FeESG-10” (16.32 g/plant). However, the highest numbers of pod (25.32) were observed with “ICGS-76”. Cultivar GG-11 had produced highest pod and seed weight (34.80 g/plant and 20.62 g/plant, respectively) as compared to other cultivars, while lowest pod and seed weight (8.96 g/plant and 6.39 g/plant, respectively) with “FeESG-8”. Maximum pod yield (2.06t/ha) was produced by GG-11 cultivars, although highest stover yield (2.37 t/ha) was produced in cultivar KAUSHAL. Cultivar GG-11 had also recorded highest shelling percentage. Therefore, it is suggested that GG-11 a better option for substituting the upland and medium land rice during kharif season for enhancing the farmer’s income.

SUMMARYWild-type Friend murine leukaemia (clone 707) cells and two thymidinekinase-deficient subclones, 707BUE and 707BUF, were compared for sensitivity to killing and mutagenesis by the chemical mutagens, ethyl methane sulphonate (EMS),N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), mitomycin C (MMC), and methyl methane sulphonate (MMS). The two thymidine-kinase-deficient subclones were significantly more sensitive to killing by each of the four chemical mutagens than were wild-type cells. The increased sensitivity to killing by the four mutagens was also reflected in increased mutagenesis (per unit dose of mutagen) to 6-thioguanine resistance. In the light of these results, the significance of thymidine kinase in DNA repair and mutagenesis is discussed.
