Mutation induction is considered as an effective way to enrich plant genetic variation, particularly for traits with a very low level of genetic variation. This research was conducted to assess genetic variation induced by gamma radiation in M2 and M3 mutant lines of canola (Brassica napus L.) by SSR and morphological characteristics and to identify useful mutants in terms of agronomic traits. ...

background and objectives: quinoa (chenopodium quinoa willd.) is a member of amaranthaceae family that originated in the andean region in bolivia, chile and peru five thousands of years and so it has a tiny and round seeds. quinoa in different combinations of food used as food, as well as how to cook like rice grains and known as the inca rice in the south american countries. the high nutrition...

peach genotypes showing notable fruit and tree traits were selected in ardabil and east azarbaijan provinces of iran. genotypes were grafted on seed rootstocks and cultured with 4×4 m spacing. traits such as tree growth habit, flowering, maturity, morphological and qualitative fruit characteristics were described in 15 peach genotypes using ibpgr peach descriptors during the 2005-2007 seasons. ...

Pigeonpea (Cajanus cajan (L.) Millsp.) is a grain legume crop from the tropics and subtropics cultivated for its highly nutritious seeds. Relatively low yields have been observed among African accession with little information on germplasm performance. Therefore, it needed to identify resilient germplasm, varieties or accessions improve agronomic This study assessed morphological variability se...

A multitrait selection index (I T ) for Zimbabwean Jersey cattle was constructed. The breeding objective was defined in terms of production and functionality traits. The production component of the index included milk yield (M), butterfat yield (F), protein yield (P), butterfat percent (F%), and protein percent (P%), while the functional component included the somatic cell count (SCC). The inde...

the aim of this study was evaluation of some of characters, estimation of their heritability and their relationship in 104 recombinant inbred lines population of durum wheat under pot and field conditions. the inbred lines, their parents and control genotypes were evaluated in completely randomized design in 3 replications at pot study and in augment design at field condition. analysis of varia...

High temperature reduces the pollen viability and silk receptivity of corn resulting in poor seed set and reduced yield. Continuously increasing temperature and less frequency and distribution of rainfall coupled with usual canal–closure particularly in Pakistan have significantly been decreasing the grain yield. This problem could be overcome by developing heat tolerant maize hybrids. For this...

the main objective for plant breeding is to increase genetic diversity. mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. the present research was aimed to compare efficacy of different doses of gamma rays (150, 200, 250, 300 and 350 gy and zero dose control) on the sesame morphological ...
