Development of Elite BPH-Resistant Wide-Spectrum Restorer Lines for Three and Two Line Hybrid Rice
Hybrid rice has contributed significantly to the world food security. Breeding of elite high-yield, strong-resistant broad-spectrum restorer line is an important strategy for hybrid rice in commercial breeding programs. Here, we developed three elite brown planthopper (BPH)-resistant wide-spectrum restorer lines by pyramiding big-panicle gene Gn8.1, BPH-resistant genes Bph6 and Bph9, fertility ...
متن کاملStudies on a Nondormant Sunflower Mutant
During the course of greenhouse studies, an unexpected sunflower mutant resulting from an interspecific cross of the wild perennial Helianthus divaricatus with cultivated HA 89 was found. In this mutant, dormancy is not induced in the developing embryo. Instead, developing seeds of the mutant sunflower begin to germinate in the head about 40 days after pollination (Fig. 1). Others have reported...
متن کاملGene-Based Marker to Differentiate Among B, A, and R Lines in Hybrid Production of Rapeseed Ogura System
Background: In plant breeding program to produce hybrid varieties, pair of male sterile and restorer fertility lines are required. Differentiation of lines possessing restorer fertility allele from the lines lacking it remove the need for the progeny test, and thus reducing the time and the cost in the hybrid production procedure. Canola breeding program in Iran has concentrate...
متن کاملHost Suitability of Commercial Sunflower Hybrids to Pratylenchus zeae.
Host suitability of commercial sunflower hybrids to Pratylenchus zeae was studied in the field and greenhouse. For comparison, one maize and one grain sorghum inbred line, both susceptible to P. zeae, were included in the greenhouse experiments. Pratylenchus zeae densities extracted from the roots of sunflower hybrids grown in naturally infested soil were low. In the first greenhouse experiment...
متن کاملDevelopment of Isogenic Restorer Line in Extra Long Staple Cotton Variety Suvin
Cotton is the most important commercial crop of India and heterosis in cotton is well documented with 7 to 50 per cent heterosis in interspecific (G. hirsutum x G. barbadense) hybrids, 10 to 138 per cent in intra-hirsutum hybrids and upto 220 per cent in desi (G. herbaceum x G. arboreum) hybrids. Currently hybrid cotton, especially Bt cotton hybrids, occupies more than 80 per cent of cultivated...
