Salinity has a significant impact on rice production in coastal, arid and semi-arid areas in many countries, including countries growing temperate rice, such as Kazakhstan. Salinity tolerant temperate japonica rice accessions were identified in this study, these accessions are important resources for breeding programs. SNPs located in the promising QTLs and candidate genes could be used for future gene validation and marker assisted selection.

"In vitro salinity stress mediates grass pea genotypes’ (Lathyrus sativus L.) responses" was carried out to determine the tolerance of grass pea genotypes to salinity stress at callus and seedling stages under in vitro conditions. The calli and seedlings of six selected tolerant genotypes based on the primary screening in the field were separately exposed to salinity treatments (0, 125 mM) in vitro.

The main of two-stage polymorphism was 67.6%, and the Polymorphism Information Content (PIC) ranged between 0 to 0.449 in the bud stage and from 0 to 0.338 from in the seedling stage. Estimation of genetic diversity and selection of prefered mutants would be considerable importance in enhancement breeding programs and to identify of genotypes with higher desirable traits for further multiplication and commercial production.

Rice growth is frequently affected by salinity. When exposed to high salinity, rice seed germination and seedling establishment are significantly inhibited. With the promotion of direct-seeding in Asia, improving rice seed germination under salt stress is crucial for breeding.

Water availability and nutrient-status of soils play crucial roles in seedling establishment and plant survival in coal-spoiled areas worldwide. Restoration of spoils pertains to the application of proper doses of nutrients and water, and selection of particular plant species for efficient revegetation.

An experiment was conducted during (2002 to 2017) to select regular bearing spongy tissue free half sibs from seedling population of mango cv. Alphonso. Elite Alphonso trees having a history of regular bearing were selected at Agriculture Experimental Station, Navsari Agricultural University, Paria, Gujarat and in adjoining areas at fields of progressive farmers.

The observations were recorded on five randomly selected plants and the mean values were subjected to Observations were recorded on 24 quantitative characters and data was subjected to statistical analysis using Mahalanobis D2 (1936) statistic to assess the genetic divergence. The genotypes were grouped on the basis of minimum generalized distance using the Tocher’s method (Rao, 1952).

Two highly effective genes for leaf rust resistance viz., Lr24, Lr28 were selected for pyramiding in the background of a susceptible but high yielding bread wheat variety DWR 162. The screening against most virulent pathotype of leaf rust 77-5 (121R63-1) indicated that both the genes confer a high degree of seedling resistance.

The experiments were conducted at Department of Plant Pathology, S.K.N. College of Agriculture, Jobner (Rajasthan). Five samples of blonde psyllium seeds were collected from Barmer, Nagaur, Pali, Jodhpur and Jalore districts of Rajasthan and tested for seed borne fungi. Both Blotter and Agar Plate methods were used to detect the maximum number of mcontrol and external seed borne fungi. A total of 5 species of fungi were identified using the two selective methods. The pathogencity of A. alternata was studied on psyllium seeds and seedlings.

A potted experiment was carried out in the net house of the Plant Breeding Unit, TRRI, Aduthurai in 2020 to screen and evaluate the performance of diverse rice genotypes for anaerobic germination ability with a view to select the suitable genotypes for multiple stress tolerance (drought and anaerobic germination) that will fit into the existing niche in the DSR. The aim of this experiment is to identify short duration genotypes with early vigour and potential to germinate under anaerobic condition.

This study was conducted to evaluate the effect of salinity on germination and emergence of chilli cultivars and to investigate the ability for genetic salt tolerance during germination and seedling growth. Although some of the chilli genotypes have salinity tolerance to some extent, more attention is required to assess the cultivars for salinity resistance/tolerance so as to screen them and select best types suitable to cultivate under areas prone to soil salinity.

In cocoa, four yielding categories viz., [‘Low’ ( 3.0 kg)] were evaluated for standardization of seedling selection criteria at nursery stage. The results showed that the highest germination percentage, seedling height, girth, number of leaves, leaf area and seedling vigour were registered in high and very high yielding categories compared to other yielding categories.

The chickpea genotype ICCV 5530, which is moderately resistant and ICCV 4991, susceptible to Ascochyta rabiei were selected to identify the changes in biochemical activity in response to infection by the fungus Ascochyta rabiei. Twelve day old seedlings were inoculated with spore suspension of the pathogen at 5 × 104 spore/ml concentration using a Haemocytometer and incubated under Controlled Environmental Facility (CEF). Sampling was done at 2, 4 and 8 days after inoculation.

The experiment was deigned to find out the best alternative way to grow healthy tomato seedling under water stress condition. Three different protected and unprotected conditions (Polyhouse, Low tunnel and open field condition) were selected for sowing of seedling. Open field condition was taken up as a control. Production of healthy and vigorous tomato seedling is most important factor in successful commercial production and yield of quality tomato fruits.

In Kagzi lime the existing variability is less due to the problem of polyembryony which suppresses the zygotic seedlings. However, to some extent variation is seen in the seedling progeny with respect to morphological, physico–chemical parameters and also in productivity. In any crop, the improvement by selection method involves identification of prosperous types from a genetic stock or population. This can be from homogeneous population of heterozygous individuals in vegetatively propagated crops or from a population resulting from hybridization.

The experiment was conducted to examine the effect of seed storage and seed treatments on seedling growth of Garcinia gummi-gutta at College of forestry, Ponnampet in split plot design in that seed storage selected as main plot and seed treatment as sub plot. In the present study seed stored up to 0, 30, 60, 90 days respectively with the eight different seed treatments. In each treatment 30 seeds were used per replication. The study indicated that seed stored up to 6o days has significant effect on growth.

Elite strains of plant growth promoting rhizobacteria were proficiently selected based on the strategic screening approaches. These included in vitro testing for plant growth promotion attributes, seedling bioassay under controlled and under greenhouse conditions. A total of 483 morphologically distinct bacteria [156 rhizosphere fluorescent Pseudomonas spp. (RSF), 206 rhizosphere Bacillus spp. (RSB) and 121 endophytic Bacillus spp. (EB)] were isolated from the roots and rhizosphere soil of coconut palms growing in different states of India.

Surveys were undertaken for characterization and evaluation of genetic diversity of Jamun (Syzygium cumini L.) of seedling origin for different horticultural traits during 2013 and 2014 in the Jamun growing areas of Jammu sub-tropical areas. Investigations were undertaken during the entire reproductive phase to assess the distribution, range and to record the range of genetic variability of different horticultural traits on the selected forty trees. Mature fruits were harvested and analyzed for different fruit characteristics.
