Morphological and physiological mechanism of cytoplasmic inheritance stigma exsertion trait expression in tobacco (Nicotiana tabacum)

Plant Science, 2023
Stigma exsertion is an essential outcrossing trait that can improve hybrid seed production efficiencies. In this study, the morphological and physiological mechanisms of cytoplasmic inheritance stigma exsertion trait expression in a tobacco line (MSK326SE) which generated from a stigma exsertion tobacco mutant through continuous backcross were ...

Molecular mapping of quantitative trait loci for stigma exsertion trait in rice (Oryza sativa L.)

Journal of Rice Research, 2021
Stigma exsertion is the most important floral trait of female parent/cytoplasmic male sterile (CMS) line for out crossing which increases hybrid seed production at farmer’s field. The present study was aimed to map the genomic regions controlling the stigma exsertion in F2 mapping population derived from IR68897B, a recipient maintainer line of ...

Inheritance Analysis for Exserted Stigma Rate in Japonica Rice

2015
Rice is the main crop in China. Since the discovery and exploitation of sterile strain line, three lines of Indica hybrid rice were bred successfully; the Indica hybrid rice has made great progress in production. Compared to Indica rice, Japonica hybrid rice is hard to study because it lacks the restorer gene. The key to promoting development of hybrid

Marker-assisted selection and evaluation of the QTL for stigma exsertion under japonica rice genetic background

Theoretical and Applied Genetics, 2006
Stigma exsertion is one of the important traits which contribute to the efficient improvement of commercial seed production in hybrid rice. In order to understand the genetic factors involved in the stigma exsertion of an indica variety--IR24--a QTL analysis was conducted using the F2 population between a japonica variety--Koshihikari--and a breeding ...

Effects of temperature and irradiance on stigma exsertion, ovule viability and embryo development in tomato

Journal of Horticultural Science, 1991
Plants of tomato cvs Marroqui, Moneymaker and Red Top were grown under four experimental conditions: high temperature (33/23°C, day/night) with summer light (467 nmol m_2s_l) (HTNI), high temperatu...

[QTL analysis for percentage of exserted stigma in rice (Oryza sativa L.)].

Yi chuan xue bao = Acta genetica Sinica, 2003
Percentage of exserted stigmas (PES) was investigated in Hainan by using a population of 127 DH population derived from a cross between a high-PES indica variety Zaiyeqing 8 (ZYQ 8) and a low-PES japonica variety Jingxi 17(JX 17) and its molecular linkage map of 234 markers.

Identification and fine mapping of a stigma exsertion mutant gene (Bolsem) in ornamental kale (Brassica oleracea var. acephala)

Molecular Breeding, 2019
Stigma exsertion is a plant trait wherein stigmas emerge from flower buds before anthesis. It is a key determinant of the ornamental kale mating system, greatly increases the efficiency of hybrid seed production, and represents a technique to promote crossing pollination.

Dissection of Additive, Epistatic Effect and Q × E Interaction of Quantitative Trait Loci Influencing Stigma Exsertion Under Water Stress in Rice

Acta Genetica Sinica, 2006
Four flowering related traits, spikelet number per panicle (SNP), percentage of single exserted stigma (PSES), dual exserted stigma (PDES) and total exserted stigma (PES) of a RI population with 185 lines under water stress and non-stress conditions for 2 years, were investigated in a drought tolerance screening facility.
