FERTILITY OF ALFALFA VARIETIES IN SELF-POLLINATION AND CROSS-POLLINATION

Bulletin of the Korkyt Ata Kyzylorda University, 2022
The article presents the results of studying alfalfa in a collection nursery by fertility, self-fertility, number of seeds in one pod, percentage of fertility of seedbuds in the ovary, number of seedbuds in one flower and seed productivity. The goal of the research is to study self-pollination and cross-pollination, fertility of a collection of ...

Cross‐Pollination Technique for Spontaneously Self‐Pollinated Sweetclover

Crop Science, 1991
There is increased interest in using a dwarf, spontaneously self‐pollinated accession (U389) of annual, white‐flowered sweetclover (Melilotus alba Desr.) for studying N2 fixation and for characterizing the photosynthetic apparatus. Genetic analysis of this accession may therefore be required.

HD-Zip proteins modify floral structures for self-pollination in tomato

Science
Cleistogamy is a type of self-pollination that relies on the formation of a stigma-enclosing floral structure. We identify three homeodomain-leucine zipper IV (HD-Zip IV) genes that coordinately promote the formation of interlocking trichomes at the ...

Insect Induced Self-Pollination

Plant Systematics and Evolution, 1984
Significant increase of pod production occurs inLupinus palaestinus Boiss. andL. pilosus Murr. following insect visits. The cause of this increase is investigated through (1) examination of the biology of pollination, (2) examination of pod production under various pollination conditions, (3) examination of cross pollination by genetical markers.

The mechanism and inheritance of intraflower self‐pollination in self‐pollinating variant strains of periwinkle

Plant Breeding, 2001
AbstractThe mechanism and inheritance of intraflower self‐pollination in self‐pollinating variant strains of periwinkle was studied using three self‐pollinating and two non‐self‐pollinating but fully self‐fertile strains. Intraflower self‐pollination in self‐pollinating strains occurred due to the continued growth of the gynoecium beyond the base of ...

Stigma factors regulating self-compatible pollination

Frontiers in Biology, 2010
Pollination is one of the most important steps during fertilization and sexual reproduction in plants, and numerous cell-cell interaction events occur between the pistil and the pollen grain/tube during this process. The pollen-stigma interaction is a highly selective process which leads to compatible or incompatible pollination.

The Makings of Self-Pollination

Science's STKE, 2007
Plants that produce both male and female gametes use various strategies to determine whether they will predominantly self-fertilize or predominantly use pollen from other flowers. Although compatibility of cell surface receptors is part of the story, the geometry of flower parts also affects what pollen lands on the stigma.

Pollination and self-interference in Nothofagus

Flora - Morphology, Distribution, Functional Ecology of Plants, 2013
Abstract Interference between male and female functions within a monoecious plant may hinder crossing and decrease seed set. We assessed the probability of self-pollination and the effect of self-pollination on cross-pollination for two self-incompatible species: Nothofagus obliqua and N. nervosa .

Breeding Self-Pollinated Crops

1987
The challenge of the plant breeder is to develop better varieties. In this chapter we are concerned with the methods by which new varieties of self-pollinated crop plants originate. Before we proceed into a discussion of these methods, let us consider the question, “What is a variety?”

Breeding Self-Pollinated Crops

2019
As a matter of fact, breeding procedures and schemes differ with the breeding behaviour of a particular species. At the beginning of each breeding programme, the breeder should decide on the type of cultivar to breed for release to farmers. The breeding method used depends on the type of cultivar to be produced. There are basic types of cultivars, viz.,
