Plasmon Mutations in Cytoplasmic Male-Sterile Pearl Millet, PENNISETUM TYPHOIDES.
Spontaneous mutations from sterile to fertile were demonstrated in four different cytoplasmic male-sterile stocks of pearl millet. One stock, ASM-3, was of African origin, and the other three, LMS-1A, ASM-5, and ASM-7, all had the same cyptoplasm of Indian origin, but differed in nuclear make-up. These reversions were shown to be plasmon mutations, rather than genic in nature. ASM-3 mutated at ...
متن کاملDevelopment of cytoplasmic-nuclear male sterility, its inheritance, and potential use in hybrid pigeonpea breeding.
Pigeonpea [Cajanus cajan (L.) Millsp.] is a unique food legume because of its partial (20-30%) outcrossing nature, which provides an opportunity to breed commercial hybrids. To achieve this, it is essential to have a stable male-sterility system. This paper reports the selection of a cytoplasmic-nuclear male-sterility (CMS) system derived from an interspecific cross between a wild relative of p...
متن کاملCytoplasmic male sterility in Brassicaceae crops
Brassicaceae crops display strong hybrid vigor, and have long been subject to F1 hybrid breeding. Because the most reliable system of F1 seed production is based on cytoplasmic male sterility (CMS), various types of CMS have been developed and adopted in practice to breed Brassicaceae oil seed and vegetable crops. CMS is a maternally inherited trait encoded in the mitochondrial genome, and the ...
متن کاملMorphological characteristics of ICRISAT-bred pearl millet hybrid seed parents1
ICRISAT had developed and disseminated a large number of male-sterile lines (A-lines) and their maintainers (B-lines) over the years, which had been characterized for key agronomic traits and downy mildew resistance in the years they were developed, but not in the common environments. Ninety-nine of these A-lines and their counterpart B-lines developed during 1981–2004 were evaluated for 26 mor...
متن کاملTransfer of Cytoplasmic Male Sterility into Rice
Transfer of Cytoplasmic Male Sterility into Rice Diversifying the existing cytoplasmic male sterility (CMS) sources of rice is indispensable for a sustainable production system of hybrid seed. Ahmadikhah et al. report that maintainer line Yosen B was converted to a CMS line (Yosen A) in three generations by markerassisted backcrossing. The recurrent parent genome content of the final CMS line w...
