A study was carried out to evaluate the effect of solid matrix priming of seeds on emergence (%), growth and fruit yield characters of bitter gourd (Momordica charantia L.) cultivar ‘Solan Hara’. The Experiment comprised of two vigour groups of seeds viz., ‘V1’ (High vigour seeds) and ‘V2’ (72 hours accelerated aged seeds/low vigour seeds) and five seed priming treatments viz., ‘P1’ (Solid matrix priming with Cocopeat), ‘P2’ (Solid matrix priming with Perlite), ‘P3’ (Solid matrix priming with Vermiculite), ‘P4’ (Seed soaking in water), ‘P5’ (Control -Without treatment).Investigation proved that low vigour seeds were inferior in respect of high vigour seeds in terms of seed physiological quality, emergence, growth and yield characteristics. Seed priming with Perlite for 72 hours proved its potential over other priming treatments, seed soaking and control (non-primed seeds) in both high vigour and low vigour seeds for agronomic attributes under study. High vigour seeds primed with Perlite ‘V1P2’ was found to be the best treatment for most of the traits understudy recording highest total field emergence (76.60%), fruit yield per plot (16.12 Kg) and per hectare (250.35 q). Similarly, Low vigour seeds primed with Perlite also recorded enhanced and improved total field emergence (73.83%) fruit yield per plot (9.28 Kg) and per hectare (143.26 q) compared to other low vigour treated and non treated seeds. From the present investigation it was inferred that that the extent of improvement w.r.t. attributes studied was more in low vigour seeds (V2) and seed priming with solid matrix carrier ‘Perlite’ can be used as a beneficial pre-sowing treatment to enhance the seedling emergence, growth and yield characteristics in bitter gourd.

Bitter gourd (Momordica charantia L.) is a popular crop grown as field and backyard vegetable in Asian countries. A field experiment was performed using Randomized Complete Block Design (RCBD) to assess the effect of plant growth regulators (PGRs) on the productivity of bitter gourd cv. Faisalabad Long. There were four treatments viz. control (no PGR), GA3 100 mg L-1, IAA 200 mg L-1 and GA3 50 + IAA 100 mg L-1, and each treatment was replicated thrice. Results revealed that untreated (control) plants took maximum days to flower (45.66), while both GA3 100 mg L-1 and GA3 50 + IAA 100 mg L-1 treated plants behaved statistically alike with 41.00 and 42.33 days, respectively. Application of GA3 100 mg L-1 depicted significant superiority for fruit length, average fruit weight, fruit yield per plant and seed yield per plant. However, statistically similar response was recorded for all the PGR treatments for male and female flowers per plant, time to first harvest, number of fruits per plant and fruit diameter; while maximum vine length at final harvest was recorded when GA3 and IAA were applied in combination. Overall results indicated that application of GA3 100 mg L-1 resulted in early crop maturity and significantly higher fruit yield per plant when compared with other treatments.

Abstract Background The preferred choice for molecular marker development is identifying existing variation in populations through DNA sequencing. With the genome resources currently available for bitter gourd (Momordica charantia), it is now possible to detect genome-wide insertion-deletion (InDel) polymorphisms among bitter gourd populations, which guides the efficient development of InDel markers. Results Here, using bioinformatics technology, we detected 389,487 InDels from 61 Chinese bitter gourd accessions with an average density of approximately 1298 InDels/Mb. Then we developed a total of 2502 unique InDel primer pairs with a polymorphism information content (PIC) ≥0.6 distributed across the whole genome. Amplification of InDels in two bitter gourd lines ‘47–2–1-1-3’ and ‘04–17,’ indicated that the InDel markers were reliable and accurate. To highlight their utilization, the InDel markers were employed to construct a genetic map using 113 ‘47–2–1-1-3’ × ‘04–17’ F2 individuals. This InDel genetic map of bitter gourd consisted of 164 new InDel markers distributed on 15 linkage groups with a coverage of approximately half of the genome. Conclusions This is the first report on the development of genome-wide InDel markers for bitter gourd. The validation of the amplification and genetic map construction suggests that these unique InDel markers may enhance the efficiency of genetic studies and marker-assisted selection for bitter gourd.
