dc.description.abstractThe present investigation entitled “Evaluation of powdery mildew resistant pyramid lines of garden pea (Pisum sativum L.) under mid hill conditions of Himachal Pradesh” was carried out at the Experimental Farm of Department of Vegetable Science and Floriculture, CSK HPKV, Palampur during rabi seasons 2017-18 and 2018-19 to identify high yielding powdery mildew resistant line(s) and to assess genetic variability and association amongst yield and quality traits in garden pea. The experiment was laid out in randomized block design (RBD) with three replications utilizing seven lines viz., Line 1-2, P116-2, P-227, P120-4, P120-1, P116-3 and P138-2 and three checks namely, Azad P-1, Palam Priya and Punjab-89. Data were recorded on yield and related horticultural traits including powdery mildew incidence. The analysis of variance indicated significant differences among lines for all the traits studied. On the basis of pod yield per plant, other component traits and powdery mildew resistance Line 1-2, P-227, P120-4 and P138-2 have been identified as promising lines for cultivation in mid hill conditions of Himachal Pradesh. High magnitude of PCV and GCV coupled with high heritability and high genetic gain was observed for number of primary branches per plant, internodal distance and number of nodes per plant. Correlation analysis indicated that pod yield per plant can be enhanced by enhancing number of pods per plant, number of seeds per pod, number of primary branches per plant, total soluble solids, pod length and number of nodes per plant. Path analysis revealed that for effective improvement in pod yield per plant in garden pea, the selection should be done for more number of pods per plant, number of primary branches per plant, pod length, number of seeds per pod, number of nodes per plant and less internodal distance.en_US
