Sieving method of nematode extraction
WebHarvest: Dry and mature plants can be harvested with a combine harvester at high capacity, and a high air flow through the sieves can remove impurities. If few immature plants are present in the field at harvest, green stems and pods might block the sieves. However, it is not beneficial to await the maturing of these few plants. WebPedigree method: for resistance breeding (disease, insect, nematode, orobanche spp) 2. Modified bulk method: for stress situations (drought, cold, heat, iron deficiency) 3. Back cross method: for interspecific hybridization. Limited backcross (one or two) for desi x kabuli introgression and also for resistance breeding.
