Evaluation of Lentil Genepool for Yield and Some Yield Related Attributes

摘要

Lentil is an important pulse crop in Pakistan which is used in combination with cereals to balance the diet. Lentil area and production is declining for the last ten year. The current study is devised to evaluate lentil germplasm for the high yield performance at the Ayub Agricultural Research Institute, Faisalabad. Hundred accessions of lentil germplasm (Lens culinaris L.) were estimated for morphological and yield related attributes. Field performance results showed that lentil lines indicated major differences for their morphological studied factors. AARI-L-540, AARI-L-302, AARI-L- 411, AARI-L-562, AARI-L-454, AARI-L-417, AARI-L- 650, AARI-L-701, AARI-L-284, AARI-L-124, AARI-L-234, AARI-L-318, AARI-L-530, AARI-L-550, AARI-L-272, genotype analyzed the maximum plant biomass, highest seed yield, 1000 seed weight, number of pods, plant height at maturity and flowering, length of reproductive phase, days to flowering and maturity, harvest index, Degree of indetermination, primary and secondary branches of plant, No of pods/plant, seed per pod, canopy temp, internode distance, no of nodes and leaves were calculated respectively. Principal component analysis statistically applied on these traits. First eight principal component analyses (PCA) expressed 88.52% of total variation in which PC I, PC II, PC III, PC IV, PC V, PC VI, PC VII & PC VIII accounted for 19.12%, 11.24%, 610.05%, 29.66%, 7.19%, 36.75%, 75.88%, 5.58% of total variation. The data was statistically analyzed to find out the superior genotype for the above mentioned character.
