Abstract Black gram (Vigna mungo (L.) Hepper), popularly known as urdbean or mash or black gram, is a grain legume rich in protein (25-28%), widely cultivated in the Indian subcontinent and to a lesser extent in Thailand, Australia and other Asian and South Pacific countries. Genetic improvement in this crop is hindered due to the narrow genetic base. As genetic variability is a prerequisite for any crop improvement programme, induced mutations provide an important source for generating variability. Radiation (gamma, X-rays and neutron) induced mutants were identified for various morphological and biochemical traits, creating a pool of genetic variability. These mutants were used in a cross-breeding programme to develop high-yielding, disease-resistant varieties in black gram. The effective blend of mutation and recombination breeding at the Bhabha Atomic Research Centre has resulted in the release of five black gram varieties (TAU-1, TAU-2, TPU-4, TU94-2 and TU-40) by incorporating desirable traits like large seed, wider adaptability, resistance to disease and improved quality. These varieties have been developed from mutants directly or by using them in cross-breeding programmes. For example, a black gram variety, N0.55, was irradiated with gamma-rays and electron beams to obtain a large number of mutants. The large-seed mutants, UM-196 and UM-201, were used in cross-breeding with the elite cultivar T-9 for developing the high-yielding varieties TAU-1, TAU-2, TPU-4, TU94-2 and TU-40. TAU-1 has become the most popular variety in Maharashtra state, occupying the maximum area under black gram cultivation. Induced mutations will continue to play an increasing role in generating genetic variability for various traits as a major component of environmentally sustainable agriculture.

<p>ABSTRACT</p><p><br />Information on genetic variability and correlation between quantitative characters with yield are important for support the selection program. The objective of the research was to estimate the genetic variability, heritability, and path analysis on agronomic characters to determine the selection criteria in the chili. This research was conducted at Research Station of Leuwikopo, Darmaga, Bogor from November 2009 until May 2010. This research observed all populations i.e. F5 population: 320 plants, IPB C2 population: 20 plants, and <br />IPB C5 population: 20 plants. The results showed that total fruit weight, thick and fruit diameter, middle fruit diameter, blossom end fruit diameter, fruit weight, and days to flowering have a high broad sense heritability . High coefficient of genetic variability values were obtained ini number of fruits per plant, fruit wei ght, stem diameter, fruit diameter, and fruit weight. Based on the heritability, genetic variability, correlations analysis and path analysis, characters that can be used as selection criteria in this study is the number of fruit per plant, fruit weight, and fruit diameter.</p><p><br />Key words: genetic variability, heritability, path analysis, selection</p>

The 52 germplasm lines of pearl millet (Pennisetum glaucum L.) were evaluated for eight quantitative characters with a view to study the genetic variability, correlation and path analysis. The High values of GCV, PCV and heritability estimates coupled with maximum genetic advance over mean were obtained for the characters like productive tillers per plant, grain yield per plant, seed weight, seed yield per ear head and panicle length traits. The results of correlation and path analysis revealed that grain yield per plant exhibited positive significant correlation with panicle length and panicle girth. The plant height, panicle girth and panicle length traits contributed the highest positive direct effect on grain yield.
