Estimation of heritability and genetic advance of yield traits in wheat (Triticum aestivum L.) under drought condition
Four varieties/lines of wheat and their crosses namely, Sakha8 , Sids1, line 1 Line3 and Line1x Sakha8, Line3x Sakha8, Line1x Sids1, Line3x Sids1 were evaluated to estimate heritability and genetic advance for yield traits. The experimental material was planted under irrigation as well as drought stress conditions. The mean average for plant height, spike length, number of spikes per plant, number of grains...
Mapping Rf3 locus in rice by SSR and CAPS markers
Cytoplasmic male sterility (CMS) is a common phenomenon that has been extensively used for production of hybrid seeds in various crops. Rf genes are needed for restoring fertility to CMS lines. Searching for and molecular tagging of restorer genes is of high importance where phonotyping is very time consuming and requires the determination of spikelet sterility in testcross progeny. In...
Monogenic lines resistance to blast disease in rice (Oryza sativa l.) in Vietnam
Blast, caused by Pyricularia grisea Cav., is one of the major fungal diseases infected rice (Oryza sativa L.) in Vietnam. This disease occurs in Vietnam which cause the yield loss of up to 20% particularly in a year with long wet season. Local varieties have been considered as genetic sources of disease resistance among crops. The breeding program was aimed at improvement of blast...
