Description For commercial exploitation of heterosis in any crop, it is to develop an economically viable mass pollen transfer mechanism. The natural out-crossing pigeonpea occurs primarily due to insect visitations. wide range of natural is reported to be due to a
number of factors, and number and types of pOllinating vectors being the most important
one. The discovery of stable male sterility systems, availability natural out-crossing and
evidence of heterotic advantage have set a perlect breaking the persisting yield
plateau in pigeon pea through hybrid breeding. In spite of six genic male sterility
based pigeonpea hybrids at the national level this technology was not adopted by seed sector.
The second breakthrough came with the development of cytoplasmic genic male sterile lines
in pigeon pea. To broaden the genetic base of newly established cytoplasmic genic male
sterility systems in pigeonpea, twelve agronomically superior and good combiner lines were
selected. These were Pusa 33, lCPL 87, GT 100, SKNP 289, SKPN 290, BDN 2, SKNP 88-3, SKNP
9523, T 15-15, T 21, UPAS 120 and lCPL 84023. These genotypes were converted into CMS
lines through simple backcross breeding method. To study the stability of fertility restoration,
41 experimental hybrids were evaluated at Kanpur, Akola, SK Nagar and Faizabad. It was
observed that the hybrids developed at SK Nagar and expressed high pollen fertility
at both SK and Faizabad. However, at Kanpur, a variation for pollen fertility was
recorded while at hybrids were almost male with pollen fertility ranging
from 0 to 35%. This data indicated a significant role of environment in the expression of fertility
restorer genes. Therefore, an attempt should be made to breed high yielding hybrid specifically
adapted to region rather than aiming for widely adapted hybrids.
