Identification and expression profiling of microRNAs involved in the stigma exsertion under high-temperature stress in tomato [PDF]

BMC Genomics, 2017
Background Autogamy in cultivated tomato varieties is a derived trait from wild type tomato plants, which are mostly allogamous. However, environmental stresses can cause morphological defects in tomato flowers and hinder autogamy.

Fine mapping a quantitative trait locus, qSER-7, that controls stigma exsertion rate in rice (Oryza sativa L.) [PDF]

Rice, 2019
Background Stigma exsertion rate (SER) is a key determinant of outcrossing in hybrid rice seed production. A quantitative trait locus (QTL) for stigma exsertion rate in rice, qSER-7, has previously been detected on chromosome 7 by using a F2 population ...

Dissection of closely linked QTLs controlling stigma exsertion rate in rice by substitution mapping. [PDF]

Theor Appl Genet, 2021
Through substitution mapping strategy, two pairs of closely linked QTLs controlling stigma exsertion rate were dissected from chromosomes 2 and 3 and the four QTLs were fine mapped.

Detection of dominant QTLs for stigma exsertion ratio in rice derived from Oryza rufipogon accession 'W0120'. [PDF]

Breed Sci, 2019
Stigma exsertion can enhance the outcrossing fertility in rice. Dominant genes for this trait are expected to be essential for the effective application of a novel outcrossing-based breeding system that uses male sterility in rice, which is normally ...

qSE7 is a major quantitative trait locus (QTL) influencing stigma exsertion rate in rice (Oryza sativa L.). [PDF]

Sci Rep, 2018
Stigma exsertion is a key determinant to increase the efficiency of commercial hybrid rice seed production. The major quantitative trait locus (QTL) qSE7 for stigma exsertion rate was previously detected on the chromosome 7 using 75 Chromosome Segment ...

Genetic Dissection of the Major Quantitative Trait Locus (qSE11), and Its Validation As the Major Influence on the Rate of Stigma Exsertion in Rice (Oryza sativa L.) [PDF]

Frontiers in Plant Science, 2017
The rate of stigma exsertion (SE) is an important trait in rice breeding because the efficiency of hybrid rice seed production can be improved by increasing the percentage of stigmas that exsert.

Four QTLs control stigma exsertion rate by changing stigma size in rice. [PDF]

Mol Breed
The stigma exsertion rate (SER) is a key trait for the outcrossing ability of hybrid rice, which directly affects the yield of hybrid seeds in hybrid seed production. In previous studies, we have located 18 QTLs for SER using single-segment substitution lines in rice. In this study, we found that 4 of 18 QTLs for SER controlled stigma size (SS).

Identification of a major quantitative trait locus and its candidate underlying genetic variation for rice stigma exsertion rate

Crop Journal, 2019
Stigma exsertion in male sterile lines of hybrid rice is important for seed yield. In the present study, ZS616 [Oryza sativa subsp. Xian (indica)], a male sterile line with a stigma exsertion rate (SER) as high as 94.5%, was crossed to DS552, a japonica ...

Fine-Mapping and Candidate Gene Analysis of qSERg-1b from O. glumaepatula to Improve Stigma Exsertion Rate in Rice

Agronomy
The stigma exsertion rate (SER) is one of the important factors affecting the seed production of hybrid rice. In the genus Oryza, wild rice species usually show higher SERs than cultivars.

Genetics of sterility behaviour in Thermo Sensitive Genic Male Sterility system in rice (Oryza sativa L. ) [PDF]

Electronic Journal of Plant Breeding, 2023
A total of 1493 F2 populations of five crosses were evaluated to study the TGMS nature under high temperature regime at Coimbatore. The present study revealed that the observed variation among 1493 F2 populations showed 25 per cent of population ...
