Combining ability analysis for yield and some of its associated characters in late sown condition in bread wheat (Triticum aestivum L. em. Thell)

Abstract

The present investigation entitled “Evaluation of exotic apple cultivars under high density planting systems of North western Himalayan region” was undertaken at experimental fields of Division of Fruit Science, SKUAST-Kashmir, during the year 2017. Eight different exotic apple cultivars introduced from Holland, of uniform age namely Mitch Gala, Elrosa, Wiltons Star, Golden Delicious Reinders, Red Delicious Camspur, Red Braeburn, Jonagold A and Jonagold DC Robijin on M9T337 rootstock, were evaluated under the Kashmir conditions for fruit and yield characteristics. Among the different varieties Red Delicious Camspur recorded the maximum fruits per cluster (3.74), fruit set (65.15), fruit retention (34.31) percentage, yield (2.66 kg/tree) as well as yield efficiency (1.03 kg/cm2). However, in cultivar Wiltons star maximum leaf fruit ratio (27.50) was observed. In terms of maturity cultivar Mitch Gala was the earliest variety to harvest while Golden Delicious Reinders being the late maturing cultivar.
