Seed Diversity of Indigenous Field Peas (Pisum sativum L.) Germplasm Collection in Oman

Pea (Pisum sativum L.) is a field crop cultivated in most countries of the Arabian Peninsula for both food and fodder consumption during winter. This paper presents the results of indigenous germplasm collections in Oman and assessment of their seed diversity. 27 seed samples/accessions of field peas were collected during collecting missions of indigenous legume crops from 2008 to 2011. South Batinah-coastal governorate represented by Rustaq (15) had the highest, followed by Dhahira & Buraimi governorates (8), Al-Dakhliya (Interior) governorate (2), Sharqiya (eastern) governorate (1) and North Batinah-coastal governorate (1). Seed accessions were found diverse for three seed traits and seed color. Seed length varied from 0.305 cm to 0.720 cm whereas seed width varied from 0.295 cm to 0.690 cm. 100-seed weight ranged from 4.500 g to 21.9 g. With respect to seed color, six accessions viz. Collection No. 25 (tan-light), No. 78 (dark green, mottled), No. 82 (light green), No. 173 (dark green, dark brown, mottled), No. 178 (brownish green, mottled) and No. 314 (cream, light pink) were homogenous (pure) whereas the remaining 21 seed accessions were heterogeneous (mixture) with various colors such as white cream, cream, light green, tan, light brown, dark brown and black with mottled nature. The collections were grouped into 10 genetically diverse clusters based on the Principal Component Analysis (PCA) using seed traits which revealed significant contribution of seed length (34.378%) and 100-seed weight (34.182%) to the total variation existing in indigenous field pea germplasm collected across all the governorates of Oman.

Field studies were conducted in 1973 and 1974 to evaluate the effects of light intensity on the quality and yield of the green field pea (Pisum sativum L.) ’Triumph’. The treatments included a control with no shading (80 klx) and shading with one (31 klx) or two (9 klx) layers of screen material for a 3-wk period before maturity. Shading resulted in a significant decrease in seed weight and yield and a significant increase in protein content of the seed. The effect of shading on viscosity of the cooked samples was quadratic, implying that viscosity only decreased at very high levels of shading. Shading also tended to reduce loss of green color in the seed cotyledons.

Cowpea (Vigna unguiculata L.) is a legume crop cultivated in whole of Arabian Peninsula countries including Oman as a dual crop for both food and fodder during summer. Both consumers and farmers prefer large size seeds. This paper presents the results of collecting missions of indigenous cowpea germplasm and analysis of seed diversity of collected accessions. The collecting mission led to the accumulation of seed samples of 64 accessions with large number from the governorates of Sharqiya (North Eastern) (19), followed by Dhofar (Southern) (17), Al-Dakhiliyah (Interior) (10), South Batinah (South Coast) (9), North Batinah (North coast) (5) and Dhahira & Buraimi (4). The accessions were diverse in respect to all the seed traits studied, i.e. seed length (cm) and width (cm), 100-seed weight (g) and seed color. The accessions were grouped into 14 genetically diverse clusters based on the Principal Component Analysis, which revealed the contribution of seed length and 100-seed weight to the total variation existing in indigenous germplasm collected from all the governorates of Oman. The results of critical examination of seed color pattern of these samples indicated the presence of as many as 31 groups of which the largest group had 16 accessions followed by a group with 4 accessions, 2 groups with 3 accessions each and 9 groups with 2 accessions. There were 19 accessions numbering 193, 197, 251, 269, 276, 280, 293, 297, 301, 303, 325, 327, 328, 331, 332, 333, 339, 343 and 347 which formed groups of their own due to a unique combination of seed coat colors.

The yellow-seeded field pea (Pisum sativum L. ’Century’) was grown at two levels of soil moisture, two levels of N and P and harvested at four dates in a 3-yr field study to determine the effects of these factors on cooking quality as indicated by the color, weight and viscosity of the puree of cooked samples. Nitrogen lowered cooking quality where yields were not improved but maintained quality when yield was increased. Phosphorus applications improved yield and cooking quality, with highest improvements in yield coinciding with greatest improvements in quality. Harvesting too early or too late resulted in lower cooking quality.

In order to best exploit the available genetic wealth in the crop, the information would have paramount important. Therefore, this study was conceived to examine the variability and determines the relative importance of primary and secondary traits as selection criteria to improve productivity. Field pea (Pisum sativum L. var. arvense) is amongst the most important legume crop of India. The experimental material comprised of 120 field pea germplasm including 40 indigenous and 10 exotic collections of pea and 4 check varieties viz., HUDP-15, HFP-4, HUP-2, Rachna. Five competitive plants from each plot were randomly selected for recording observations for all the quantitative characters except days to 50 per cent flowering and days to maturity, which were recorded on line basis. In present study a strong and positive association of seed yield per plant observed with harvest index, biological yield per plant, plant height, number of seeds per pod, number of primary branches per plant, number of pods per plant and 100-seed weight. Days to maturity and number of seeds per pod showed positive correlation with days to 50 per cent flowering and number of primary branches per plant respectively. Days to maturity and 100-seed weight and number of pods per plant showed weak association with seed yield per plant in positive direction. Thus, these characters emerged as most vital component traits and associated positively with seed yield per plant.

High Yields

The effects of seeding dates on yield, seed weight, percent protein and protein yield of field peas (Pisum sativum L.) were determined by seeding four cultivars at five dates from 1970 to 1973 at two locations in Manitoba. Early seeding resulted in higher yields and heavier seeds. Protein content was lower in early-seeded peas, but the protein yield per unit area was higher than the late-seeded peas. In Manitoba, field peas should be seeded before the 1st of June to obtain high yields of both seed and protein.

100 Seed Weight

A total of 80 diverse germplasm accessions of common bean (Phaseolus vulgaris L.) were collected from 31 different locations known for marginal and risk prone farming systems in remote and hilly areas of North-Western Indian Himalayan state of Jammu and Kashmir. The variability was observed in seed color, shape, size and 100- seed weight. Thirteen colors of bean seeds were represented in these 80 accessions with high predominance of red colored seeds. Cuboid, kidney and oval seed shapes observed were represented respectively in 61.25%, 25% and 13.75% of the accessions. There were significant variations in seed length, width and 100-seed weight being highly significant in the later case. All the three seed size classes (small, medium and large according to CIAT categorization) were represented in the collected accessions. 22.5% accessions have 100-seed weight less than 25g, 53.75% accessions have 100-seed weight between 25-40g while 100-seed weight of more than 40g was recorded in 23.75% of the accessions. Highly positive correlations were found between 100-seed weight and seed length and width and between seed length and seed width. The 80 accessions were grouped in three clusters at a coefficient level of 0.3 with largest cluster of 59 accessions followed by a medium cluster with 20 accessions and the least with a single accession. Grid maps generated through DIVA-GIS software indicated that diverse accessions of common bean in terms of seed size and weight can be sourced from the areas falling in Budgam, Shopian and Kulgam districts of the state. Conservation of this remarkable genetic diversity is recommended for future propagation, breeding and the investigation of the genetic relationships.
