PublicationArticle Variability, character association and path coefficient analysis of green pod yield and its related traits in pea (Pisum sativum L.)(Agricultural Research Communication Centre, 2017) Keshav K. Gautam; M.M. Syamal; A.K. Singh; Nakul GuptaGenetic variability, character association and path coefficient studies were carried out for yield and yield contributing characters for twenty-four diverse genotype of pea. The results revealed a wide range of phenotypic variation, along with high heritability in pea. Highest pod yield per plant was recorded in VRP-229 followed by VRP-372 and VRP-305. The characters namely, plant height and weight of seeds per pod showed high magnitude, while number of pods per plant, number of branches per plant and pod yield per plant showed moderate magnitude for phenotypic and genotypic coefficient of variation. The heritability and genetic advance were high for days to first pod initiation, plant height and pod yield per plant indicating its additive gene action for their expression. Character association studies revealed that pod yield per plant exhibit positive and highly significant correlation with number of pods per plant, number of branches per plant and days to fifty percent flowering. The path coefficient studies also revealed that maximum positive direct effect was observed through number of pods per plant followed by days to first flowering, single pod weight and pod length towards yield indicated that these characters may be considered as the most reliable selection indices while making selection for high yielding genotypes. © 2017, Agricultural Research Communication Centre.

SrivastavaIn the present experiment 56 diverse pea genotypes were chosen belonging to seven different plant type groups and observations were made on eight traits related to yield and lodging. Normal foliage with reduced stipule plant type (stst genotype) found to be shortest (in terms of days to flowering and days to maturity) while, semi-leafless plant type had the highest 100-seed weight as compared to the normal plant types (LeLe AfAf TlTl StSt). On the other hand, the pleiofila with reduced stipule foliage type (afaf tltl stst) had smallest 100-seed whereas, seed yield per plant was highest in case of semi-leaf plant types in both tall and dwarf groups. Similarly, Pleiofila with normal and reduced stipule plant types in both tall and dwarf groups were found to be more lodging susceptible than the normal.The dwarf/ semi-dwarf genotypes combined with semi-leafless peas appear to be the most ideal plant type that would provide better tolerance to lodging and yields high. © 2015, Indian Society of Genetics and Plant Breeding.

SrivastavaInformation about slow rusting resistance to pea rust (Uromyces fabae) is limited. Five slow rusting components, i.e. area under disease progress curve (AUDPC), latent period (LP), number of pustules per leaf (NPL), pustule size (PS), number of aecial cups (NAC) and sensitivity of leaf to rust (SLR), were evaluated in 38 pea genotypes under field conditions. Estimates of correlation coefficients indicated a high negative association of LP with AUDPC (r = −0.751; P ≤ 0.001), NLP (r = −0.808; P ≤ 0.001), PS (r = −0.458; P ≤ 0.001) and NAC (r = −0.476; P ≤ 0.001). However, significant positive association was found between AUDPC and NPL (r = 0.78; P ≤ 0.001), PS and NAC (r = 0.545; P ≤ 0.001). Factor analysis showed that, three of the slow rusting components, i.e. AUDPC, LP and NPL accounted for 49.77% of the total variance as the first main factor, while the other three traits distributed within the next two factors determined 26.34% and 10.46% of the total variance, respectively. A multiple regression analysis showed that the variation in AUDPC was significantly explained by number of pustules followed by latent period. Selection for slow rusting could be based on one component since they are interdependent but, for accumulating more partial resistance in a line, selection should be based on more than one component studied. © 2015, Journal of Plant Pathology.

Singh; Mandhata Singh; Zulutemjen Jamir; O.P. SrivastavaA field experiment was conducted during winter season of 2006 - 07 and 2007 - 2008 to study the effect of different fertility levels (Fertility level F1: 30-20-2.5, P2O5-S-Zn kg/ha and Fertility level F2: 60-40-5, P2O5-S-Zn kg/ha) and micronutrients on plant growth, nodulation, production potential of pea. Results indicated that fertility level F2 (60-40-5, P2O5-S-Zn kg/ha) was found most effective in enhancing the plant growth, nodulation, yield attributes, yield, nutrient content in nodules and nutrient uptake by crop. Improvement in different form of N viz NH4-N, NO3-N, organic N, available N and total nitrogen were registered with higher fertility level. Amongst the micronutrient, combined application of micronutrients enhanced the plant growth, nodulation, yield attributes, yield, nutrient content in nodule and nutrient uptake. NH4-N, NO3-N, organic N, available N and total nitrogen were also recorded higher with combined application of micronutrients. Grain yield and nutrient (N, P and S) uptake by crop also increased to a great extent by the combined application of micronutrient (B 0.3% + Co 2+ Mo1 kg/ha) under fertility level F2.PublicationArticle Genetic diversity studies in pea (Pisum sativum L.) using simple sequence repeat markers(2013) P. Kumari; N. Basal; A.K. Singh; V.P. Rai; C.P. Srivastava; P.K. SinghThe genetic diversity among 28 pea (Pisum sativum L.) genotypes was analyzed using 32 simple sequence repeat markers. A total of 44 polymorphic bands, with an average of 2.1 bands per primer, were obtained. The polymorphism information content ranged from 0.657 to 0.309 with an average of 0.493. The variation in genetic diversity among these cultivars ranged from 0.11 to 0.73. Cluster analysis based on Jaccard's similarity coefficient using the unweighted pair-group method with arithmetic mean (UPGMA) revealed 2 distinct clusters, I and II, comprising 6 and 22 genotypes, respectively. Cluster II was further differentiated into 2 subclusters, IIA and IIB, with 12 and 10 genotypes, respectively. Principal component (PC) analysis revealed results similar to those of UPGMA. The first, second, and third PCs contributed 21.6, 16.1, and 14.0% of the variation, respectively; cumulative variation of the first 3 PCs was 51.7%. © FUNPEC-RP.PublicationArticle A quantitative analysis of rust (Uromyces fabae) resistance in pea (Pisum sativum) using RILs(2012) A.K. Singh; R. Rai; C.P. Srivastava; B.D. Singh; C. Kushwaha; R. ChandIn a quantitative analysis of pea rust resistance using a RIL population, heritability estimates for disease severity and AUDPC were found to be 0.90 and 0.93, respectively. High heritability indicated that selection for pea rust resistance can be made under polyhouse conditions using either disease severity or AUDPC as disease reaction estimators. Average degree of dominance (ADD) for resistance to U. fabae was 0.11 and 0.14 for disease severity and AUDPC, respectively, indicating that the genes controlling U. fabae resistance exhibited a low degree of incomplete dominance. Estimates of the minimum number of effective genes conferring resistance to pea rust, using three different methods of estimation, varied from two to three.PublicationArticle Production potential and nutrient uptake efficiency of pea (Pisum sativum L) as influenced by different fertility levels and micronutrients(2012) D.K. Singh; A.K. Singh; Mandhata Singh; L.J. Bordoloi; O.P. SrivastavaA pot experiment was conducted during 2005 and 2006 to study the effects of cobalt, boron, molybdenum on yield of and nutrient uptake by pea under graded levels of soils fertility. At higher level of soil fertility [F2: P2S2Zn2 (60:40:5 mg pot-1 of P2O5, sulphur and zinc)], growth and yield performance of the crop along with nutrient uptake was significantly better irrespective of the micronutrients applied. Maximum grain and vine yield (140 and 183 g pot-1, respectively) of the crop was recorded at higher level of soil fertility. At every level of fertility, micronutrients application augmented the growth and yield of the crop along with nutrient uptake. Combined application of the micronutrients proved superior to their sole applications. Sole application of Co was significantly better than those of B and Mo in boosting up the crop performance. Approximately, 67% increase in number and weight of nodules was observed over control owing to sole application of Co. At every level of fertility, maximum uptake of N, P and S was contributed by combined application of Co, B and Mo although sole application of Co also yielded quite comparable results.PublicationArticle Variability and interrelationships of slow rusting components in pea (Pisum sativum L)(2008) C.P. Srivastava; V.K. Singh; A.K. Singh; R. Chand; C. Kushwaha; B.D. SinghRust [Uromyces fabae (Pers. de Bary)] is an important disease of pea (Pisum sativum L). Slow rusting or partial resistance has earlier been reported in pea and other legumes. Forty-six genotypes of pea were screened to study the nature and extent of relationship among slow rusting and its components. Highest GCV was recorded in number of non-bursting pustules per leaf, AUDPC and number of pustules per leaf. High heritability accompanied by high genetic advance was observed in AUDPC, number of pustules per leaf and number of non-bursting pustules per leaf. The association study of different characters indicated that AUDPC was significantly associated with number of pustules per leaf, sensitivity, number of aecial cups and pustule size.
